Description

Cardamine diphylla is a spring blooming woodland wildflower. It is similar to Cardamine concatenata, and though it is less common, it is often found in the same habitats. Its basal foliage emerges from the root stalk and is comprised of 2 leaves, each divided into 3 roundish, toothed lobes. Whitish flower clusters appear at the end of 8" to 16" tall stems. They are cross-shaped, four-petaled and appear in spring before, or as the tree foliage emerges.

Cultivation

Crinkleroot is native to moist, rich deciduous forests, where it enjoys the filtered light allowed to pass through the leafless trees of early spring. It is intolerant of the deep shade provided by evergreen trees. The blooming period occurs during early to mid spring, from March to May, depending on geographic location. Zones: 3-7

Propagation

Easily propagated by by separating its rhizomes once the plant goes dormant. Can be propagated from seed, but new plants can take up to 4 years to produce flowers. Collected seeds should not be store, as they will quickly lose viability.

Additional Notes

The common name "pepper root" is a reference to the spicy flavor of its fleshy rhizomes. These can be eaten raw, mixed in with salads just as you would radishes. Toothwort is a reference to the tooth-like projections on the rhizomes.
