(aka: Cardamine diphylla) Dentaria diphylla 'Supermax' is a newly named large-leaf selection of the Eastern US (Maine to Mississippi) native toothwort with the largest foliage we've seen in the species. Each three-parted leaf measures 7" long/wide, compared to a typical 3.5" long x 4.5" wide leaf. We originally acquired our plant from garden writer Pam Harper as Dentaria maxima, which it obviously isn't. We've grown this amazing selection since 1996, in which time, it's made a thick 5' wide, weed-suppressing woodland groundcover. Dentaria 'Supermax' goes summer dormant, re-emerging in late fall/early winter. The patch of tripartite dark green leaves, adorned with muted silver veining is topped with 10" stalks, terminating in clusters of white bells in early-mid April (NC). Light shade and average to moist soils (acidic or alkaline) are preferred.
