Nursery contributed plant descriptions

Our collection, probably of the variety frutescens, from near Weaverville in the Siskiyou Mountains of southern Oregon. This evergreen, rounded tree to about 25', produces crinkled, somewhat spiny, deep green leaves, silvery bark, and most attractive missile shaped acorns in late summer through autumn. A tough species for the droughty west and one of the most easily moved at larger sizes. Nice planted where one might want contrast to an olive as they reach about the same size. From this elevation we expect frost hardiness to be below 0 °F, into USDA zone 6. Full sun, well-drained soil, preferably on a steep cliff, but not necessarily so. [SBH 7198]
