2 2 USDA zone: 2 Cornus alba 'Hessei' tartarian dogwood An ornamental, deciduous dogwood that is perfect for the small garden, growing to only 6-8 ft tall x 8-10 ft wide, with multiple, upright branches, the stems bright yellow in winter. Late spring flowers are white in flat clusters, producing white fruit in fall, both lovely against the curly, densely held, dark green leaves. Cut back in early spring for new growth in the best winter color. Makes a useful small hedge or screen. Very adaptable, enjoying sun -- except in the hottest climates -- to part shade and regular summer water. Frost hardy to -50F, USDA zone 2. $16 Cornaceae USDA zone: 3 Adiantum pedatum northern maidenhair fern Native to eastern North American on wooded slopes and dampish shade sites, this sweet maidenhair fern has frilly fronds arranged in a circle on wiry, nearly black stems to 1-2 ft tall in clumps to 1-2 ft wide. Where happy, can spread by rhizomes to form large colonies, a lovely and delicate groundcover for part to full shade where soil is rich and summer water is plentiful. Often grown indoors as well, tolerating low light. Frost hardy to -40F, USDA zone 3. $9 Adiantaceae Carex mertensii merten's sedge Western native sedge, found growing in moist to wet areas from Alaska to California and east to Montana. Bright green leaves form clumps to 15-20" tall, topped in summer with graceful, dangling clusters of overlapping flowers on tall stems. Does well in sun where moisture is plentiful, along waterways and even in boggy ground. Frost hardy to -40F, USDA zone 3. $9 Cyperaceae Hemerocallis 'Secured Borders' daylily A stunning, variegated daylily, the grassy leaves appearing in spring with a narrow, green center on a white field, the result of careful breeding over many years by Sybil and Walter Przypek of Virginia. Plants are small, to 12" tall in clumps growing to 18" wide. Into summer yellow flowers appear above the foliage which has turned to green in the warm weather. A lovely plant and a collector's dream. For full to part sun with regular summer water. Frost hardy in USDA zone 3. $16 Xanthorrhoeaceae Hosta 'Blue Mouse Ears' This super-cute hosta is a mutation of H. Blue Cadet, proving that sometimes a little mutation is good. In this form small silver-blue leaves, slightly rolled at the edges, form rounded clumps, to 8" tall x 1 ft wide, topped in early summer with short, sweet spikes of lavender flowers. Best in light shade to shade where the soil is rich and summer water is regularly supplied. Frost hardy to -40F, USDA zones 3. $16 Liliaceae / Asparagaceae

3 Opuntia fragilis - Michigan tiny form brittle pricklypear This form, from a population in its far northeastern range, indeed Michigan, was found in wind-exposed outcrops or in mats in the mosses and lichens. Each pad is under 1/2" in length and width, often under 1/4", with a slightly blue cap and not many spines. This little prickly pear is best in bright light and quite water tolerant. Has been frost hardy into USDA zone 3. Good container plant for your artic condo. $11 Cactaceae Opuntia polyacantha 'Peter Pan' hedgehog prickly pear Collected by Kelly Grummons in Colorado's Pawnee National Grasslands, this stunning, perpetually juvenile, non-flowering form has pads of 1-3" covered in bright, white spines. Forms a spiny, white carpet to only 3" tall and spreading slowly to up to 2 ft wide. A good selection for rock gardens or troughs in sun and welldrained soil. Drought tolerant. Frost hardy to -40F, USDA zone 3. $12 Cactaceae Opuntia x rutilia These seem to be intermediate population between O. polyacantha and the ubiquitous O. fragiis coming from the western Colorado plateau. This very pretty form has 3" or so robust pads, purple tinted and turning much darker in winter, with rust and white spines emerging firey orange. The flowers are medium pink in mid spring. Easy in container or garden given bright light and half-way decent drainage. Probably frost hardy to -40F, USDA zone 3. $11 Cactaceae Viburnum opulus 'Aureum' golden leaf european cranberry bush This smallish, striking viburnum has leaves that emerge bronze in spring, aging to dark yellow then turning green as summer approaches. Umbrels of white spring flowers are intensely fragrant and showy against the bright foliage. Bright red berries follow in late summer holding on as long as the birds allow. To a compact 4 ft tall x 5 ft wide, this viburnum makes a statement in the woodland garden in part shade to full sun in coastal areas. Expects regular summer water. Frost hardy to -40F, USDA zone 3. $12 Caprifoliaceae / Adoxaceae 3 USDA zone: 4 Arachniodes standishii upside-down fern Much sought-after and hard to find fern from Japan and Korea with handsome evergreen to semi-evergreen fronds that are almost frilly in appearance and from 1-3 ft long. Forms clumps that reach 2-3 ft wide after many years, spreading by underground rhizomes. For light to deep shade with average summer water. Frost hardy to -30F, USDA zone 4. $22 Dryopteridaceae

4 Aster ageratoides var. ageratoides 'Ezo Murasaki' An aster that has it all! Compact and sturdy to 2 ft tall and wide - the clumps gradually spreading to 8-10 ft wide - plants are covered in the fall with bright purple flowers that bloom over a very long period and stand up against frost and fall drizzle. Sun to part shade with summer water. Still difficult to find outside collector s circles these deserve a greater presence in the gardener s autumn palette. Evergreen to 10F, USDA zone 8 and root hardy to -30, zone 4. $12 Asteraceae Cheilanthes argentea silver cloak fern This fragile looking fern, native to rocky outcrops in China and Japan, is far from a wimp. Drought tolerant, easy, and gorgeous with fronds that are glittering green above and a ghostly, silver-white below. Best in walls, rock gardens, or containers, anywhere excellent drainage can be provided. Drought tolerant once established and said to be deer resistant. Frost hardy to -30F, USDA zone 4. $12 Adiantaceae Cornus mas 'Variegata' cornelian cherry A grail plant for many, this strikingly variegated form of the deciduous cornelian cherry, with its green leaves marked in white, reaches ft for us, with a compact umbrella shape, and yellow flowers in mid to late winter, followed by deep red, 1/2" fruit (with a pollinating partner) -- indeed, quite tasty, attracting birds, and making a lovely contrast with the glowing, variegated leaves in mid to late summer. Prefers rich moist soil in part shade but does well in full sun with mulch for cool roots and generous summer water. Frost hardy -30F, USDA zone 4. Does poorly in very hot places with high humidity. $18 Cornaceae Cornus sanguinea 'Compressa' dwarf bloodwood dogwood "Interesting", "unique", "strange", "tough", and "distinct" are all words used to describe this red twig dogwood, a very upright and narrow, dedicuous shrub, possibly reaching 6-8 ft x 3-4 ft wide. The leaves are wrinkled, veiny, curly and densely held on the stems, a textured addition to the garden, while the crowded, upright stems offer bright red, winter interest. Sun to part shade with regular summer water is best. Frost hardy to -30F, USDA zone 4. $12 Cornaceae Cornus sericea 'Hedgerows Gold' red twig dogwood A red-twig dogwood cultivar with the bright red stems that color the winter landscape after the leaves are gone. And what wonderful leaves - bright green with a wide and irregular golden edge! In spring, clusters of tiny white flowers appear followed by white fruit that birds love. This deciduous shrub, to 6-10 ft x 6 ft, can be multistemmed or trained as a small, handsome tree. Best in bright light with protection from afternoon s hottest sun and regular summer water. Tolerates a wide range of soils, including boggy situations. Frost hardy to -30F, USDA zone 4. $12 Cornaceae 4

5 Delosperma congestum 'Gold Nugget' ice plant We found this ice plant growing at 10,000 ft elevation just east of Sani Pass on the border of South Africa and Lesotho, forming a dense growing cushion of only 1" tall by 10" wide, with stunning yellow flowers. These have become popular in the mountain states (think Denver) for their extreme cold hardiness (-20F) when soil is well drained. Tough and pretty in the sun. Frost hardy to -20F, the bottom of USDA zone 5. $7 Aizoaceae Epimedium grandiflorum 'Dark Beauty' Gorgeous little barrenwort, selected by Harold Epstein for the chocolate-purple, spring foliage that forms a perfect backdrop for the large, late spring flowers of purple and white. Foliage turns green through the summer. To 8-12" tall and wide in part sun to dappled shade. Drought tolerant once established but accepts summer water. Frost hardy to -30F, USDA zone 4. Said to be deer resistant! $15 Berberidaceae Euonymus europaeus 'Red Ace' spindle tree The most expensive plant Exuberant Garden s Dorothy Rodal ever purchased, having fallen in love with its scarlet seed pods that open to reveal dusky orange seeds -- just as everyone does who sees it. And now we have enough to share. A large, deciduous shrub to small tree, to 8-10 ft tall x 8 ft wide, with 3" leaves that turn a flaming, crimson red in autumn. The flowers in small, yellow-green clusters are not showy but produce the exquisite and abundant fruit that IS showy. Native to Europe and western Asia. Frost hardy to -30F, USDA zone 4. $14 Celastraceae Ginkgo biloba 'Weeping Wonder' dwarf maidenhair tree Strange and wonderful new ginkgo introduction, a dwarf tree growing only 6-10 inches per years into tiny upright tree, eventually 4-5 ft tall with side branches that are horizontal to weeping. Adding to the interesting texture, the foliage is somewhat twisty and pale to dark green in summer, depending on the light, turning typical ginkgo yellow in the fall. Occasional trimming maintains good shape and form. Enjoys sun to part shade with regular summer water. Frost hardy to -30F, USDA zone 4. $22 Ginkgoaceae Hydrangea arborescens 'Emerald Lace' smooth hydrangea An unusual and unique hydrangea, found in Illinois by Stan Tyson, with dark green foliage, ragged and deeply, irregularly lobed with occasional crest formations. Summer flowers are white lace-caps. A deciduous shrub, reaching to 4-5 ft tall x 3-4 ft wide over time and enjoying bright light to part shade with regular summer water. Blooms on new wood; can be cut back hard in late winter. Frost hardy to -25F, mid USDA zone 4. Sometimes found as H. arborescens 'Green Dragon'. $15 Hydrangeaceae 5

6 6 Iris 'Black Gamecock' [Louisiana hybrid] Stunning, dark, purple-black flowers, very large with just a touch of lime in the throat make this a must-have iris, with its lovely, 2-3 ft tall, narrow leaves, handsome in their own right. Growing naturally on the Louisiana Gulf Coast and inland marshes, they are very easy in the moist border or actually sitting in water at pond edge or bog, forming clumps to 3 ft wide. Full sun and acid soil for best growth. Frost hardy to -30F, USDA zone 4. Said to be deer resistant as well. $12 Iridaceae Juncus effusus bog rush, common rush Clump forming rush, to 2-4 ft tall and wide, with rounded, upright, leafless stems, a nice cheerful green. Flowers in summer, the inconspicuous blooms emerging yellowish brown from the sides of stems. A great accent in the garden and good in containers or submerged tubs. Sun to part shade. Tolerates wetland conditions as well as garden soil with summer water. Spreads by underground rhizomes and can seed itself. Frost hardy to -30F, USDA zone 4. $8 Juncaceae Kerria japonica 'Albescens' white japanese kerria Deciduous shrub, enjoyed especially for its single flowers with oddly shaped petals in creamy, pale yellow. To 6 ft tall and wide, but easily trimmed, these are lovely in early to mid spring when covered with flowers. Fine in part shade to full sun with occasional summer water. Said to be deer resistant. Frost hardy to -30F, USDA zone 4. $15 Rosaceae Kerria japonica 'Picta' japanese kerria Variegated Japanese kerria -- not your grandmother's plant -- with toothed, triangular leaves of grayish green edged in white on a spreading shrub to 2 ft tall and wide over a few years. Flowers in spring, producing abundant, single, yellow flowers, showy against the textured foliage. Best in part shade, out of the hottest afternoon sun, in fertile, well-drained soil with summer water. Blooms on last year's wood so prune after flowering. Frost hardy to -30F, USDA zone 4. Occasionally found as K. japonica 'Variegata'. $11 Rosaceae Leucosceptrum japonicum 'Golden Angel' japanese shrub mint Lovely golden-foliaged shrub for the shade garden, a Japanese perennial that keeps its color throughout the summer. (May fade where summer nights are warm, but plants are easily refreshed by hard pruning.) To 1-3 ft tall and wide, this little charmer creates a bright spot in morning sun or light shade with summer water. Grown primarily as a foliage plant, but also produces pale yellow, fragrant bottlebrush flowers in autumn as an added bonus. Frost hardy to -30F, USDA zone 4. $14 Lamiaceae

7 Lewisia cotyledon [mixed seedlings] bitterroot One of northern California and southern Oregon s most beautiful native wildflowers. These are seedlings and can be expected to produce an eye popping range of flower colors, the exact color unknown for individual plants but all should be charming. The evergreen rosettes are handsome as well, offsetting slowly to add more plants and more color. Give these sun and excellent drainage and enjoy the show. May go deciduous in too much heat or cold, but they are frost hardy to -30F, USDA zone 4. $9 Montiaceae Opuntia 'Cyclops' cyclops prickly pear Though the name has been around a long time, this plant's origins are unclear We do know this is a cute little prickly pear to 1 ft or 18" in height, probably having O. macrorhiza in its ancestry, with rounded pads of 4-6" forming tight clusters with dark bunches of spines appearing as polka dots from a distance. Cheery yellow flowers appear in mid to late spring. Good for container or sunny garden. And, as one would expect, very drought tolerant though west of the Sierra or Cascades would like a drink from the hose once in a while to spur growth. Frost hardy to -30F, USDA zone 4. $12 Cactaceae Opuntia 'Dark Knight' hedgehog prickly pear This striking opuntia, a Claude Barr selection, has long white spines on distinctive pads of purple green, becoming more purple in winter cold. Colorful and even more so in late spring to early summer when the bright, lavender-pink flowers with golden stamens first appear. To 10" tall x 4 ft wide in sun and lean, welldrained soil. Frost hardy to -30F, USDA zone 4. $12 Cactaceae Opuntia 'Golden Globe' prickly pear A Cistus introduction. From one of our favorite cactus habitats not far north of the aptly named Cactus Mountain Oregon, we believe actually named for particularly large specimens of pediocactus growing on its flanks. This selection from an obviously hybrid colony (parents = Opuntia polyacantha x erinacea var. columbiana) has shaggy upright pads to about 5" creating clumps 8-10" high by 3-4 ft wide with densely petalled flowers of undulating gold yellow, the orange stamens combining to create quite a show. Careful drainage is a must with these cliff dwellers and full sun. More summer drought tolerant than other prickly pears. Probably frost hardy to -30F, USDA zone 4. $15 Cactaceae Opuntia 'Peach Chiffon' prickly pear A wonderful new strain of prickly pear with a profusion of silky, peach colored flowers in June on very compact plants, to under 6" tall forming clumps to 30 wide. n extremely prickly creature for full sun to light shade in well-drained soil. Drought tolerant but happily accepts occasional water. Frost hardy to -30F, USDA zone 4. $12 Cactaceae 7

8 Opuntia 'Red Gem' prickly pear A gorgeous little prickly pear given to us by Colorado's Kelly Grummons and we could find no better description than this with hopefully enough credit due: "An apparent hybrid between O. basilaris or O. aurea with O. fragilis! To 4" high x 18" wide, with small, round, 2-3" wide pads that have very short spines and are fragile (pads break off easily). The petite, deep pinkish red flowers in June are abundant. Beautiful in the rock garden or in containers. Fergusen thinks this MAY be Opuntia polyacantha v. schweriniana still a mystery." Frost hardy to -30, USDA Zone 4. $12 Cactaceae Opuntia aff. columbiana IB 06 - H65 Collected by plantsman Ian Barclay near Naches, WA where the forms of small padded opuntias are numerous and varied. This form has small, flattened, 1" pads producing downward pointed golden spines and pleasing yellow flowers on clumps to 3-4" tall and spreading. We thank Ian for finding this clone; we love it! More tolerant of winter moisture than many other opuntias and a good pot specimen. Frost hardy to -30F, USDA zone 4, or below if that is possible. $11 Cactaceae Opuntia aurea 'Coombes Winter Glow' creeping beavertail cactus Old opuntia selection that is very hardy but, for unknown reasons, now much harder to find. We like it for the unassuming green pads that turn dark red-purple to nearly black in cold weather. To 2 ft tall and up to 3 ft wide with cerise flowers appearing in June. Tough and easy in lean, well-drained soil with lots of sun and little summer water. Frost hardy to -30F, USDA zone 4. $11 Cactaceae Opuntia basilaris 'Peachy' beavertail cactus This beavertail cactus, a native from the Mohave desert of California into northern Sonora, was given to us from an old Albuquerque garden and has been one of the best performers. Attractive clumps, from 3-4 ft wide and 18 in height, with 6 pads of powdery blue-tinted-pink, burgundy in winter, and, indeed, peachy pink flowers in spring and early summer. Though a clone more tolerant of garden water, they still prefer welldrained, gritty soil, especially where winters are wet and an occasional thunderstorm, artificial or not, in dry summer climates. Frost hardy to -30F, USDA zone 4. $12 Cactaceae Opuntia basilaris ssp. whitneyana SBH 7775a beavertail cactus Plants from these colonies close to 8700 ft elevation near Mt. Whitney in the eastern Sierra Nevada received some of my first collection numbers during a hike just after high school. This more recent collection from the same area forms a rather dense clump of blue-green pads, to about 4", with neatly spaced, orange glochids and abundant purple-pink flowers in late spring. Has been easy in cultivation though seems to like a well-drained mix whether in the garden or in container, the granite scree in which it grows naturally being a good indicator. Frost hardy to -30F, USDA zone 4, or lower. 8 $12 Cactaceae

9 Opuntia basilaris var. brachyclada 'Mormon Rock' A Cistus introduction from the vicinity of Mormon Rock in southern California. This tightly clumping small form of beavertail has conical blue pads somewhat more flattened than the typical subspecies indicating a possible hybrid. Whatever the botanical case, each pad is only about 3" wide with well-spaced, bright orange glochids giving the whole plant a very cheery appearance. Nice medium-to-cherry-pink flowers appears in mid spring. Not minding extra winter moisture, these are a bit easier to grow than other beavertails, enjoying full sun. Excellent pot or rock garden plant and frost hardy to -10F, USDA zone 5, probably zone 4. $15 Cactaceae Opuntia basilaris var. heilii - Type local beavertail cactus Named for botanist Ken Heil and collected from the northeastern population of the beavertail cactus. This clone, found growing in heavy alkaline soil in south central Utah and collected via a single pad years ago by plantsman Tim Hannis, produces dense clusters of blue-bodied plants, rather short on glochids, a good thing! It has been our favorite so far growing robustly and producing abundant, warm pink flowers in late spring. Easy in in the ground or container provided full sun and good drainage. Frost hardy to at least -30F, USDA zone 4. $12 Cactaceae Opuntia fragilis - Red Butte brittle pricklypear A Tim Hannis collection from a small hill of the same name in Utah. The pads are quite thick, somewhat flattened, to 3" with sturdy golden and white spines. Makes small clumps to about 18" wide. Another very good rock garden, tough or container plant. Frost hardy to at least -30F, USDA zone 4. $11 Cactaceae Opuntia fragilis - Sequim, Washington brittle pricklypear From a collection by Ian Barclay near his wonderful nursery in Sequim Washington, this rainshadow population growing on rocks near the Puget Sound might not be the most beautiful form in the world but it certainly is interesting -- a rather sparsely spined creature, forming open clumps with occasional light yellow flowers. It is always a surprise to come across a prickly pear west of the Cascades Mountains and these have surprised many a beachcomber taking a break on nearby rocks. Sun for sure. Frost hardy to -30F, USDA zone 4. $11 Cactaceae Opuntia fragilis 'Little Gray Mound' brittle pricklypear Very cold hardy little cactus, to only 3" tall in clumps to 12" wide, with brownish red glochids and pads that turn purple in cold weather. Produces bright yellow flowers in early summer. Tolerates part shade but prefers full sun and good drainage; tolerates drought but enjoys occasional summer water. Cold hardy to -35F, USDA 3b. Also fine in containers. $9 Cactaceae 9

10 Opuntia fragilis (debreczyi) var. denuda 'Potato' potato cactus This variety of the fragile prickly pear from the western Colorado plateau tends to be almost entirely nekkid, not even having the tiny glochids we've come to enjoy. A favorite of rock and trough gardeners, these have round pads, to under 2", that clump to at least 3 ft wide but only a few inches in height, turning purplish in winter and producing occasional lemon-yellow flowers in mid spring. This clone shared with us by Western Colorado's Don Campbell. Frost hardy to -30F, USDA Zone 4, possibly lower. $12 Cactaceae Opuntia fragilis SBH 6778 [Ashland, OR] brittle prickly pear Lovely compact form, Sean's collection from the dry hills east of Ashland, Oregon. To only 4 or so. Slow to bloom but when they do, the flower color is deep, chartreuse-yellow. This one is capable of withstanding any amount of winter moisture -- short of submersion. Frost hardy to at least -30F, USDA zone 4. $7 Cactaceae Opuntia fragilis th.073 [Salinas Creek] brittle prickly pear Another find from southern Utah by plantsmantim Hannis, these small, round, padded clumps, to 4-5" tall and 18" wide, are adorned with cream and white spines and gold glochids. Occasional yellow flowers appear in mid spring. Cute little pot, container, or rock garden creature for full sun. Frost hardy to -30F, USDA zone 4, possibly colder. 10 $11 Cactaceae Opuntia fragilis th [Monticello, UT] brittle prickly pear From plantsman Tim Hannis, this cutie with 1", purple-blushed pads becoming even more purple in winter making a nice contrast with the orange and white spines. Stands out from quite a distance in the garden or container. Another easy to grow cactus needing only sun and moderately well-drained soil. Frost hardy to -30F, USDA zone 4. Very good in container or garden. $11 Cactaceae Opuntia fragilis var. denudata 'Bronze Beauty' marble cactus This little beauty has small, rounded pads, to only 5" tall, that are dark green turning reddish bronze in bright light and cool weather and forms handsome and colorful clumps to 15" wide with obvious orange glochids but no spines. In late spring to early summer, large, pale yellow flowers appear turning peachy for their second day. Best in full to to light shade and lean, well-drained soil. Drought tolerant but occasional summer water improves appearance. Frost hardy to -30F, USDA zone 4. Also known as A. fragilis 'Bronze Beauty. $9 Cactaceae Opuntia fragilis x 'Metolius' A Cistus introduction. From a probable stable hybrid population of O. fragilis and O. polyacantha collected east of Mr. Jefferson Oregon, the upwardly held 3-4" pads have well-spaced, pale cream spines, darkening with age, and yellow spring flowers, not in abundance. Creates a nice bold texture for container or a spot in the garden. Care as with other O. fragilis... easy with good light. Frost hardy to at least -30F, USDA zone 4. $12 Cactaceae

11 Opuntia fragilis x polyacantha (?) [Nyssa, Oregon] This population, now almost gone because of nearby farming, covers the parched, alkaline shadscale-covered hills near Nyssa, Oregon. Probably an intermediate between O. polyacantha, or O. erinacea, and O. fragilis, the half-dome clump consisting of 3" long, bluish pads strikingly adorned with long white spines and orange glochids. Yellow mid-spring flowers age towards pink. This, one of our more unusual collections, has been quite easy in cultivation given bright light. Probably frost hardy to -30F, USDA zone 4. $12 Cactaceae Opuntia polyacantha 'Citrus Punch' prickly pear Another beautiful prickly pear from Colorado's Kelly Grummons, this spreading creature of under 1 ft in height but eventually to 3-4 ft wide has orange and yellow spines and warm apricot flowers darkening with age. Superb in rock gardens or containers and frost hardy to -30F, USDA zone 4 or below. Full sun and sharp drainage. $12 Cactaceae Opuntia polyacantha 'Imnaha Blue' A Cistus introduction. A common native of western dry lands, this clone, from northeastern Oregon's Imnaha Canyon, was found weeping several feet off a cliff of red ryolite, the nearly spineless, gray-blue pads appearing almost as if hanging in chains. Assuming not everyone has a cliff, these will form spreading mats to 4-12" tall and up to several feet wide. Early summer flowers are a warm, soft yellow. Ordinary cactus requirements -- sun, lean and well-drained soil, and little or no summer water. Undoubtedly frost hardy into USDA zone 4. $12 Cactaceae Opuntia polyacantha 'Imnaha Sunset' A Cistus introduction. A common native of western dry lands, these found in northeastern Oregon's Imnaha Canyon. They have round to oval pads -- from 1-4" long with dense, orange spines (polycantha means "many thorns) up to 2" long -- and form spreading mats to 4-12" tall and up to several feet wide. Early summer flowers are, in this selection, yellow with orange stamens and particularly abundant. Frost hardy at least into USDA zone 4. $12 Cactaceae Opuntia polyacantha SBH 7505b A Cistus introduction and a vigourous plant, growing to 15-18" tall x about 3 ft wide, with shaggy white to straw colored spines completely obscuring the pads. n mid to late spring saturated yellow flowers appears each aging tangerine in time, giving a bi-colored effect. Seems to flower best when allowed to grow as it pleases so be lenient. Needs full sun, good drainage. Good in rock gardens, troughs, or containers. Frost hardy to -30F, USDA zone 4. $14 Cactaceae Opuntia polyacantha x - San Rafael Swell A Tim Hannis collection from southern Utah, this possible hybrid has small, 2-3", rather flattened pads with white to straw-colored spines all forming dense clumps to about 18" wide or so and only 4" tall. The flowers appear in some abundance of rose-pink aged white. Easy both in container and in the ground given normal prickly pear conditions in sun with moderately good drainage. Frost hardy to -30F, USDA zone 4, or lower. $11 Cactaceae 11

12 Opuntia polyacantha x SBH 7503c A Cistus introduction. A diminuitive little thing, this O. polyacantha, seemingly introgressed with O. fragilis or possibly someone else, forms a rather dense clump of flattened pads, to only 2-3", with pale spines and, in mid to late spring, flowers of a rather intense gold with contrasting red stamens. Another easy to grow prickly pear for container, rock garden, or jewelry in good light for best spine and flower formation. Frost hardy to at least -30F, USDA zone 4. $12 Cactaceae Opuntia potsii var. montana A wonderful little cactus from Santa Fe, New Mexico, to only 4" tall x 30" wide, with green pads and very short spines. Summer flowers are lemon yellow, single and simple. Best in lean soil, good drainage, and bright light, though these are more shade tolerant than most opuntias. Needs little to no summer water. Frost hardy to -30F, USDA Zone 4. $12 Cactaceae Opuntia whipplei 'Tiny Tim' A Cistus introduction, but we must thank Tim Hannis for finding this northernmost Utah population of O. whipplei and particularly for this striking clone. These spiny, miniature chollas, reaching only about 6-8" in height but spreading to 6 ft or more, are variable in color with 1-2" long "pads" covered with golden spines. Even these small plants manage to produce a number of yellow-green flowers each spring followed by yellow fruit. A most attractive garden "shrub" or container specimen for sun and decently drained soil. Frost hardy to -30F, USDA zone 4. $12 Cactaceae Opuntia wrightii - white spine Small cholla from northern Arizona and adjacent places --perhaps more familiar by its old name and synonym, Opuntia wrightii - white spine, this collection does have white spines rather than the silvery spines of the genus. Tightly held branches form a miniature tree to about 3 ft tall. Greeny yellow flowers are abundant in mid spring. Easy to grow in bright light and gritty soil with occasional summer water. Frost hardy to -30F, USDA zone 4. A very good container specimen. $15 Cactaceae Opuntia x rutila - red/black spines This so far unnamed hybrid was an early Colorado Plateau collection by plantsman Claude Barr. Stout orangered and black spines mark pads roughly 3" long, the elongation suggesting parentage by O. polycantha and O. fragilis. Mid spring, yellow flowers fade to apricot. Wonderful for small rock gardens with the usual cactus conditions -- sun, lean and well-drained soil, and little or no summer water. Frost hardy to -30F, USDA zone 4. $12 Cactaceae 12

13 Philadelphus 'Manteau d'hermine' dwarf mock orange A superb and compact mock orange for a small garden or tucking in anywhere that sweetly scented, spring flowers in profusion would be welcome. This 100 year old cultivar is only 2/5-3 ft tall x 5 ft wide with small but dense, light green leaves creating a fine-textured presence and backdrop for the sweet, sweet double flowers that open from a reddish bud in late spring. Deciduous and very presentable without its leaves. Sun to part shade in rich soil with regular summer water. Frost hardy to -30, USDA zone 4. $12 Hydrangeaceae Sambucus nigra 'Eva' black elderberry Also sold under the name 'Black Lace,' this is an elderberry that knows how to behave itself... or so we are told. Leaves are shining black-purple, deeply cut, and layered on a deciduous, somewhat dwarf shrub to 8 ft tall if left unpruned. Add the contrast of spring flowers in soft pink flowers followed by dark red berries... berries that are delicious in pies, jams, and pancake syrup! Fun for all seasons. Sun is best and supplemental summer water. Frost hardy into -30F, USDA zone 4. $14 Adoxaceae Ulmus parvifolia '11th Avenue' This lovely selection of the semi-evergreen Chinese elm, propagated from a specimen on Portland's 11th Avenue, has small glossy leaves, mostly evergreen in warmer parts of its range, though a cold winter can strip the leaves. Deciduous in the colder zones, with fall color from yellow to red-purple. The bark is corky and mottled, exfoliating with age to combinations of gray, green, orange, and brown. Resistant to Dutch elm disease and city air, this is an excellent street tree, somewhat vase-shaped and reaching a luxurious ft tall and wide in sun and well-drained soil with regular until well-estalblished summer water. Frost hardy to -30F, USDA zone 4. $15 Ulmaceae Vaccinium macrocarpon 'Pilgrim' american cranberry Grow your own cranberries with good, rich, acid soil, well-drained but able to hold moisture. No bog required. These small, evergreen groundcovers, to only 6" tall, have small, shiny leaves, and in summer, little pink bells that produce abundant, large purple-red berries in autumn.

15 Agave utahensis ssp. kaibabensis SBHMPS 6747 utah agave From the Tuweep area on cliffs and mountaintops on the northern edge of the Grand Canyon abyss amid junipers and beautiful red rocks... and far away from restaurants that serve alcohol, our collection of a particularly wide and long leaf form of the highly variable Utah agaves, producing nearly 18 rosettes of a cheery blue-green with dark, evenly set spines. I believe this colony to be under the form kaibabensis. These plants offset rather sparsely to make attractive clumps rather than colonies. After 10 years or so, flowers spikes rise to nearly 10 ft.

As denizens of the southern Great Plains, they love a thunderstorm or two in the summer and don't mind being dry in the winter, though they are tolerant of moisture.
