Cardamine diphylla, commonly known as two-leaved toothwort or crinkleroot, is a native spring wildflower that produces delicate white four-petaled flowers above distinctive toothed leaves. This woodland perennial emerges early in spring, blooms for several weeks, then goes dormant by midsummer as trees leaf out overhead.
In an HOA neighborhood
Broadleaf Toothwort takes more care to keep looking intentional in a front yard. Maintenance level: low. Consider it for backyard or mid-zone beds rather than the street edge.
Works well in: backyard only.
- Goes completely dormant by midsummer leaving bare patches
- Spreads by underground rhizomes which may concern neighbors
- Appearance too wild and ephemeral for formal landscaping
Wildlife value
The early spring flowers provide nectar for native bees and flies when few other food sources are available. Seeds are eaten by birds and small mammals.
Native range data from the USDA PLANTS Database and regional native plant society lists. Pollinator and host plant associations compiled from GBIF, iNaturalist, and published ecological literature.
