Thalictrum occidentale

Smaller growing western meadow rue is a resident of deep moist woods as well as the margins of streams. Many divided leaves are delicate and flutter in the slightest breeze. Each indented leaflet is perched in the arrangement of an arrow. In mid to late spring wiry stems extend above the 1′ tall foliage another 10″ and displays flowers that are comprised of raspberry and brown downward pointed flowers. They make an evenly distributed display that is not so much showy as it is incredibly graceful. Loved by pollinators who swing by for the suspended pollen. Best in enriched soil with consistent irrigation in summer. It spreads to form large colonies and is exceptionally pretty crawling up a low bank or hill. Winter deciduous perennial. This species which is more of an upland species requires a little less water than the similar but taller Thalictrum fendleri but it still requires irrigation in summer, even when well established. Benefits greatly from a top dressing of mulch. Companion plants in habitat are Tellima grandiflora, Mitella, Heuchera and Delphinium . Prefers protection from mid day sun and will burn and/ or die in hot dry situations. ‘Forms expanding colonies. Very good woodland pollinator perennial with a wonderful texture. Moderately deer resistant. Oregon native plant.
