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.
