Nursery contributed plant descriptions

O'Brien Bog. A Cistus introduction. Dwarf Oregon myrtle (or dwarf California bay if living south of 42 degrees north). A normally stately tree in the avocado family inhabiting western Oregon and coastal California, these Siskiyou endemic forms reach only 6-8' as dense shrubs with evergreen leaves emerging bronze and aging to deep green. This clone becomes a dense, pyramidal form with leaves held upright displaying bluish undersides. A perfect chance to acquire this wonderful species in a manageable size. Small clusters of brush-like, yellow flowers produce shiny, green, nearly 1" “avocados” in autumn. Aromatic leaves can be used as seasoning (they are related to the Grecian Laurus nobilis). Should be an iconic shrub for the West Coast. Drought tolerant for sun or part shade. Frost hardy to -10 °F, USDA Zone 6, at least.
