This widespread species is native to the floor of the Willamette Valley and is locally common in the Columbia Gorge where it occupies dry rocky hillsides in full sun but tolerates heavy clay soil. In the best conditions (loam) it is huge spreading perennial that requires pre-planning and some real estate. Gray green stalks and leaves rise up to about 4’tall and bear deliciously fragrant pink orbicular flowers. These are irresistible to butterflies, including Monarchs, and if you want one to visit your garden this plant is good insurance. However, all butterflies find it irresistible. Spreads underground vigorously by stolons and can come up quite a way from the initial clump. Full sun and well drained soil. Completely winter deciduous and emerges relatively late in spring. Be patient. see video below. IMG 6323. Oregon native plant.
