Heterotheca villosa

Hairy Solidaster is a stand out perennial west of the Cascades,never common it inhabits dry rocky areas and it is almost the only thing still in bloom in September. A somewhat sprawling evergreen perennial to 1′ x 2′ wide for full sun to very light shade in average, unimproved  native soil. Bloom begins in July and it is yet another important late season pollinator plant for the Willamette Valley. Native primarily along the gravel slopes of major rivers. It can also be seen on occasion in abandoned rock quarries. Sunny yellow flowers are vivid and once this plant is established it can survive on rainfall alone. Very appropriate trailing over sunny rock walls.  The leaves are somewhat sticky an adaptation to drought. Cold hardy and summer drought adapted. It may be cut back hard in early spring to refresh. Easy to grow with neglect. Combine with Epilobium (Zauschneria), Oenothera macrocarpa., Helianthemum ‘Henfield Brilliant’. Excellent butterfly attractant.  Oregon native plant.
