Arrow-leaved Groundsel

Senecio triangularis


Perennial herb with a fibrous-rooted stem-base or rhizome; stems clustered,30- 150cm tall, yellow flowers, heads few to numerous in a short, flat-topped base. Leaves are basal, thin and broadly to triangular-heart-ahped, squared off at the base. The large, triangular, saw-toothed leaves make ID of arrow-leaved groundsel almost foolproof. Thanks for the help with the ID Jean!


Moist to wet, meadows, streambanks, thickets, open forest, typically a subalpine to alpine species, but also in seepage areas in middle elevation forest; common and often abundant.


The Pacific Fritillary seemed to love this plant! Here is the fritillary spotting where it is on another plant which I haven't identified yet.
