Named for Martha Washington, not for the State of Washington, Lilium washingtonianum and its variants enjoy a wide range. Found as far north as Mt. Hood, Oregon where locals call it the "Mount Hood Lily", but can be found far south as Yosemite. The pure white, trumpet-shaped flowers carry varying amounts of purple spots. As with Lilium rubescens, these blooms deepen in color with age to lavender. Near impossible to cultivate, it is commonly found growing in nothing more than gravel alongside logging roads. Long lived in the wild, bulbs can be covered by several feet of rubble spilling down rocky hillsides.
