Camas

Camas was the primary food source for native people of the Pacific Northwest. It keeps very well, particularly if roasted first, and is high in protein as well as sugars. It is nowhere near as pervasive as it was even 25 years ago, and it's become clear that its abundance in former times came about due to human nurturance, and building malls and parking lots on its camas swales (flat land near rivers) has hindered it quite a bit. It likes to keep its feet wet, doesn't mind flooding or wet summers or wet winters, can withstand freezing temperatures (due to its bulb's depth) and grass fires. Its bulbs do not get large and mature in a single year, so it hasn't been used for modern agriculture, but I hope people will consider doing so.
