Suitable for the rock garden or alpine house. Slow- growing evergreen conifer making a small shrub of spreading, bushy growth. Foliage gold- yellow. Bark is white with cinnamon tones. Original tree was selected in 1985 from progeny of B. platyphylla var. szechuanica x B. pendula 'Purpurea,' made in 1978. Bark is slightly exfoliating when mature. The dark green quality foliage is retained until late autumn. Fargo has been shown to be well adapted in Fargo, ND.

Tree with very irregularly horizontal crown, stem also frequently divided with many leaders. Found frequently in the wild since 1836; also observed in cultivation. Conical type that matures slowly into a beautifully compact, broadly pyramidal plant, the perfect dwarf Christmas tree.
