Steens Mountain yarrow
Tucked away in southeastern Oregon is an ancient ridge known as Steens Mountain. From those decaying glacial cirques comes this special little yarrow. Distinctive for its low,dense green foliage and short flower stalks reaching a height of about 6 inches. The flowers are white with umbels about two inches wide. Blooms from spring through autumn. A useful diminutive yarrow for the rock garden or small space. Doesn’t spread as aggressively as its lowland kin but forms nice dense mats. Provide full sun and water occasionally once established. Deer resistant.
