The genus name refers to Dr. William Tolmie who was a physician for the Hudson's Bay Company at Ft. Vancouver in 1832. The species name refers to Archibald Menzies who was the first European to botanize the Pacific Northwest.
Origin: Neophyte (established after 1500 AD). It is a native of western N. America. It is introduced in 1812 and was recorded from the wild by 1928.
