From Mississippi to Nova Scotia, and Minnesota to Maine, Tiarella cordifolia has a very large native range in North America. This makes Tiarella very adaptable, and it's hardy from Zones 3-8. Now that's a wow factor. Right now, our benches are brimming with excellent cultivars of Tiarella cordifolia.
I'd like to highlight "The River Series" bred by our friend, Sinclair Adams. These runner types were named after Eastern Pennsylvania's rivers, 'Susquehanna', 'Lehigh', 'Delaware', 'Octoraro', and the 'Brandywine'. Sinclair says,"In using native names for these fine native plants,we hope these river choices increase public awareness about regional and global water concerns."
Another excellent running type of Tiarella that we offer is 'Running Tapestry'. Some of the clump forming cultivars are 'Oakleaf', 'Dark Star', and wherryi. Each of these cultivars have a unique foliage pattern and interesting dark veins.
One of my favorite places to visit is Longwood Gardens. In Pierre's Woods, Tiarella is concentrated under massive trees.
Foam flower is one of the common names for Tiarella. They like it in the well drained, open air of a forest. There is a six week bloom window to enjoy the sea of white froth under those trees.
So catch the wave of Tiarella. Use less mulch at the tree roots, and plant Tiarella. Brighten up space under shrubs and trees, in between perennials in the garden, and in combination planters.
