Acacia pravissima

We wouldn't have guessed we could grow Acacia here in our cold pocket garden but we had a random seedling of this appear in our never-water Arctostaphylos/Garrya bed and it has not had a bit of damage from several winters down to 10F. Poofs of yellow flowers among the evergreen leaves. Lean soil, great drainage and dry. Cutting-grown plants from our one mystery origin plant. Large shrub to small tree.
