Everything seems to flower at once in May, either in full sun locations or under the shade cover. Between them all, these two delicately delightful plants, from the finest of North American natives: one flowering in the shady side of the woods and one in my sun exposed rocky containers.
Thalictrum thalictroides (formerly Anemonella thalictroides) – Rue anemone
Aquilegia scopulorum – Utah Columbine
Both are easy to propagate and cultivate. A. scopulorum is a high altitude columbine, with very long (25-40 mmm), strait spurs, characteristic to almost all NA Aquilegia spp. In the wild habitat it grows on rocky slopes (limestone cobbles); perfect for the rockery, trough or crevice garden. (from Wrigthman Alpines)
