I came upon some stray foxglove flowers while driving on a forest road in the King Range National Conservation Area, Humboldt County, California.
Growing in a ditch across the road, under some ferns. I think it's Digitalis purpurea
Quite showy on this little hill...
Digitalis purpurea (foxglove, common foxglove, purple foxglove or lady's glove), is a species of flowering plant in the genus Digitalis, in the family Scrophulariaceae, native and widespread throughout most of temperate Europe. It is also naturalised in parts of North America and some other temperate regions. The plants are well known as the original source of the heart medicine digoxin, (also called digitalis or digitalin).
