Sanicula crassicaulis

Pacific Snakeroot is a fascinating native perennial that is native west of the Cascades from British Columbia south -to the tip of South America.  A summer deciduous perennial whose presence is really from January to July- before slipping into summer/dry dormancy. This unique plant forms handsome palmate leaves that are edged in black when young.  As summer approaches the plant elongates up to 30″ tall and begins to bloom. Tight gold/charteuse inflorescence  that must attract very specific pollinators. I know for a fact that it draws butteries because I vividly remember them visiting this plant in the country. I’ve always found this easy growing plant pleasant and I have to admit that it is present in just about every biome west of the Cascade Crest. At the coast it is nearly evergreen – no need for summer dormancy. The small spiny seeds that perch at the top of plant are carried away by animals. Adapted to a LOT of soil conditions including compacted xeric clay. Forms increasing rosettes to 18″ across. More than likely you will find seedlings. Found in the Willamette Valley with Dodecatheon, Camassia, Rosa, and in shade with Symphoricarpos and Polystichum. Full sun to full shade. Not eaten by deer. Oregon native plant.

Sanicula crassicaulis Pacific Snakeroot is common in Willamette Valley Oak Savanna.
