|}}Erigeron cascadensis is a North American species of flowering plants in the daisy family known by the common name Cascade fleabane. It has been found only in the state of Oregon in the northwestern United States, primarily in subalpine meadows in the Cascades mountain range.[2]Erigeron cascadensis is a perennial herb up to 15 cm (6 inches) tall, producing a taproot. One plant can produce several flower heads, sometimes one per branch, sometimes in groups of 2 or 3. Each head has 30–50 white or purple ray florets plus numerous yellow disc florets.[3] References1. ^The Plant List, Erigeron cascadensis A.Heller {{Taxonbar|from=Q15593069}}{{Astereae-stub}}2. ^Biota of North America Program 2014 county distribution map 3. ^Flora of North America, Erigeron cascadensis A.Heller, Cascade fleabane 3 : Erigeron|Flora of Oregon|Plants described in 1900 |
