Lupinus Rivularis, Streambank Lupine

Day 244: There are many species of Lupine to be found in western Washington, from the tiny Lupinus lepidus which grows in the poor soils of alpine areas to the enormous Lupinus latifolius which may reach up to four feet in height. Although many species contain poisonous alkaloids, some were prepared for use as food by the indigenous peoples of the area.

A vigorous grower, Lupines are members of the family of Legumes, related to the Vetches and Clovers. If you look closely at each individual blossom, you will see that they are shaped like pea flowers. With a few exceptions, wild Lupines are bluish or purplish in hue. They have been cultivated and hybridized to produce the other shades which gardeners love.
