|Another wonderful plant to add to the garden if you want to attract hummingbirds. Soft pink flowers are borne of racemes from summer to fall. Leaves are linear and toothed, mid- to dark-green. This compact clump-forming, perennial requires some shade and moist conditions. Perfect along streams or where conditions are moist to boggy and acidic. Can grow to a height of 3 feet and 1 foot wide.
