Mahonia piperiana
‘Piper’s Oregon grape’ is found in southern Oregon and northern California. Hummingbirds visit the abundant fragrant yellow blossoms which are best produced in a sunny environment.
Charles Vancouver Piper (1867-1926) was born in Victoria, B.C. but spent his youth in Seattle, then a territory, and graduated from the UW in 1885. He compiled the first guide to the flora of the PNW. Most famous for his work with the USDA in Africa on grasses and in China on soybeans. Besides this plant, an orchid genus is named for him too.
