Title: Flower with spike of yellow flowers with hairy purple filaments
Answered by: Nan Hampton
This does sound like a beautiful plant. Unfortunately, I couldn't find it in our Native Plant Database. The plants that do come to mind, however, are the Verbascum species. They are about 2 feet tall with spikes of yellow flowers. In particular, Verbascum blattaria (moth mullein) is described as having hairy purple stamen filaments. The flower petals can be yellow or white tinged with pink. It is not, unfortunately, a native plant but an introduced species from Eurasia. Its distribution includes nearly all of North America and it appears on the Colorado State List of Noxious Weeds. There are other species of Verbascum, all introduced, that occur in North America and some even occur in Oregon, but none have the hairy purple filaments like those of V. blattaria.
