Collinsonia, or Richweed, flowers captivate with intricate details resembling a miniature insect face, featuring a frilly lower lip, extended filaments, and beard-like hairs in the throat. This charming appearance is complemented by a delightful citronella-like fragrance emitted by both the flowers and leaves.
More Information About Collinsonia
Collinsonia is a genus of mint relatives (Lamiaceae) native to eastern North America, containing some members that are popular as herbal remedies for a variety of ailments. However, we are interested in Collinsonia's ornamental characteristics, and it has those, too. Collinsonia species are herbaceous shade plants that produce late summer clusters of small, pastel colored flowers that upon close inspection reveal a wonderful little frilly beard on the lower petal. The plants are not unlike some woodland garden Saliva species in form and function with a loose, coarse habit.
