Thalictrum kiusianum (Dwarf meadow rue)

This clump-forming variety has unusually long, maple-shaped leaves with a chocolate-colored overlay. It is topped in spring by 16-inch spires of pink buds which yield to wispy, starlike ivory flowers. Plants rebloom lightly, so they can flower from spring to mid-summer. 'Mint Chocolate' grows to about 16 inches tall and a foot wide.

This clump-forming variety has very dramatic, deeply cut foliage with wide black veins that looks like a black snowflake when new. The dark color is more pronounced in cool weather. Plants produce a profusion of starry white flowers on numerous spires up to 12 inches high and grow to about a foot wide. Tiarellas are at home in moist woodland environments. In the garden they make wonderful carpets of intricate leaves. For a long period from spring into summer, the profusion of foamy flowers can be appreciated up close or from a distance. Grow 'Black Snowflake' as a groundcover or edger in a shady border or woodland garden. It is a great foil to early spring bulbs.

This reblooming, clump-forming variety blooms in spring, producing 15-inch spires densely packed with pink blossoms. Its deeply cut foliage is compact, with black markings along the midrib. Plants grow to about 10 inches tall and wide. 

This clump-forming variety has exquisitely textured, bright green maple-like leaves emblazoned with chocolate centers. In spring, its large pink-kissed-white flowers rebloom lightly on 16-inch stalks. Leaf coloration is best in cool weather. Plants grow to about a foot wide.
