Large Toothwort

Cardamine maxima

Large Toothwort (Cardamine maxima) is a landscape plant valued for its form and structure as much as its bloom. Large Toothwort is sized and grown for a real yard, not a show bench. Match it to full sun to part shade and water it in for the first season while roots establish. One caveat: like any plant, its published range is a guideline, not a guarantee, for the specific microclimate of your yard. Given a spot that matches its light and water needs, it is a dependable, low-drama addition to the yard.
