The Nooka lupine grows along roadsides, gravel bars, and forest clearings from the Aleutian Islands, southcentral Alaska, and along the Panhandle to B.C. Rigorous self-seeders, lupine can often be seen along roadsides and in open meadows, their bright blueish purple flowers catching ones eye from quite a distance. Their long tap roots make transplanting difficult, so sowing seed is preferable.

A member of the pea family, lupines form seeds in fuzzy pods that may be attractive to children. The seeds of the lupine can be toxic, though toxins flush through the system quickly and are not cumulative. However, internal use is not advised.
