Tiarella is one of my favorite spring-blooming natives. It’s in bloom right now. It perhaps is 8 inches high on a good day; I wish it were 8 feet. Here’s a photo of a small clump that’s growing in one of my shade gardens:
There are several species of Tiarella native to North America and Eurasia. Tiarella cordifolia is our native eastern species. It likes partial or full shade and medium soil moisture (my soil is very dry and sandy, so although the tiarella comes back every year and blooms nicely, it doesn’t spread as enthusiastically as I would like it to). The leaves are heart-shaped and somewhat variegated. If your site is even somewhat moist, this plant could gradually form a lovely groundcover for you.
