1 Gardening f Bees - Seasonal Recommended Lists: The following lists are based on several years of evaluation and survey wk done in Nthern and Southern Califnia by our UC research group. s are presented seasonally, and in alphabetical der, based on the same scheme used in Sunset Magazine's Western Garden Book (2007), edited by Brenzel. Some infmation on Califnia native plants is also found in s of the San Francisco Bay Region by Beidleman and Kosloff (University of Califnia Press, 2003) and in Wildflowers of the Santa Monica Mountains by McAuley (Canyon Publications Co. CA, 1996). Below you will find seperate lists f Spring plants and Summer plants, as well as a key to the shthand used f bee groups/species in the tables. If you have trouble printing this page, if your browser is having trouble displaying it properly, there is an unstyled set of lists available. Finally, if you would like to have a ptable copy of the lists, perhaps send them to a friend, we have a nicely fmatted PDF version available f download (Latest revision: December 2007). F me infmation, see the additional text at the bottom of this page. Spring s Scientific Name SSArctostaphylos spp. Common Name Family Origin Annual Perennial Pollen Nectar Manzanita Eric.

5 Vitex agnus-castus Chaste Tree Verben. Exotic Per P/N Xylo, B,, Key To Bee Groups B hid sb X And Mel P Bombus (Bumble Bee) hidium (achilidae) One of the many varieties of small bees. Xylocopa (Carpenter Bee) ia (achilidae) alictid Andrenid achilid (Leaf Cutter and Mason Bees) hophid (Digger Bees) European oney Bee Melissodes (an hophid) atina (Small Carpenter Bee) Peponapsis (Squash Bee) Additional Infmation on the Seasonal Recommended Lists Most infmation used to create these lists (F example; plant fm, flower col, soil and cultivation requirements) can be found in the Sunset Garden Book. Local nurseries can also be helpful with specific infmation. All of the plants listed here will flower within one two years; most during the first year of planting. Other evaluated plants (f example, large shrubs and trees) known to be attractive to bees can be found in our exhaustive Complete List [PDF] (last compiled December, 2003). F best results in bee gardening, we recommend that advanced planning takes place to insure that continual bee flal food will be available f both Spring and Summer seasons. There are distinct groups of bees present in Spring and in Summer; some groups can also be observed year round. In our experimental gardens in the Bay Area we always plant a minimum of diverse bee plants each season. igher bee diversity and abundance occurs when gardens have a rich asstment of bee plants. It also appears that bees remain longer in a garden if plant diversity is high. Finally, we find that patch size of about 1 meter in diameter larger is best f keeping faging bees visiting a given plant species cultivar. Smaller patch sizes, of usually attractive plants, will often be igned. Once your bee garden is established, be sure to take time to closely observe the different bee groups/species that will visit your plants. Each bee species behaves slightly differently than all others, which helps in identification. Bee watching can be as enjoyable as bird watching once your eyes get adjusted to their movements. Note also that certain bee groups/species will be predictably found on certain plant types. 5 of 5 1/19/10 11:14 PM
