      Plant Information

      Hailing from valleys adjacent to the Cascades as well as the coastal strip the finely divided foliage of this clumping perennial is attractive but enhanced when the clusters of very pretty flowers open the palest pink aging to lavender over several days. Full sun to part shade in rich moisture retentive soil. To 28″ tall and somewhat spreading. Blooms for an extended period from April to June. Summer drought will bring dormancy but a little bit of water keeps it green. Great tolerance to dry clay soils and it persists in conditions that would end lesser perennials. Mixes well at the margins of woodlands or the front of perennial borders. Even in its habitat it tends to flop, or rather lean on its neighbors. Expect this and use it to an advantage. The softly colored flowers will wind into other plants playfully and you can achieve really cool and wild appearing vignettes. Very good in concert with native Geranium oreganum as they bloom simultaneously. A really pretty native perennial. Adaptable to heavy clay soils. Soars in rich, amended soils and can be quite a bit larger than I’ve listed. Fairly good cut flower. Oregon native plant.

      USDA Hardiness zone: Zn6a -5º to -10ºF
