Erigeron Acris


Day 322: Yeah, I know...it's another DPD (Damn Purple Daisy), but in defence of Erigeron acris, I will say that its scarcity and size make it special. The flowers are thumbnail-sized, pale lavender, borne singly on branching stems. The mature seed head is a ball of fluff destined for distribution by autumn winds, although the seeds must not travel very far from this site. When I first discovered the plant several years ago, there were only a few in evidence. Now there is a thriving population which covers at least 500 square feet, wiry stems rising above thin, dry soil in a rocky draw. That said, it is not a rare plant in the Pacific Northwest by any means, just unusual for this particular location. Although it may not be as showy as other larger composites, Erigeron acris is one of my favourite native "asters."
