Cut -leaved toothwort - cardamine concatenata(c) 2011 Patty Hankins

One of the wildflowers that blooms in early spring in the Washington, DC area is Cut-Leaved Toothwort (most sources refer to it as cardamine concatenata – formerly known as  Dentaria laciniata). I’ve seen it blooming as early as mid-March at the National Arboretum in DC. When the cut-leaved toothwort blooms – I know that the other wonderful spring wildflowers will soon be blooming as well.

A member of the Mustard family (Brassicaceae) are edible. In early spring, used it leaves as an herb. The leaves were often cooked in bacon grease or soaked in vinegar. In the fall, the roots were used to add a peppery flavor to food.

It was also used medicinally by Native Americans. It was used for everything from headaches to colds to heart disease. If men put it in their pocket, it could supposedly be used to attract women. Ceremonially, toothwort was used for divination. There are also reports of its use as a hallucinogen – where is supposedly could help mesmerize a person. Under the Doctrine of Signtaures, toothwort was useful for treating tooth problems.

Cut-Leaved Toothwort is easy to identify once you know what it looks like. It grows to between 6 and 12 inches tall. The single stem is topped with a cluster of four petaled white or pink blossoms. The leaves are whorled with three toothed leaves on the upper part of the stem.

I’ve photographed Cut-Leaved Toothwort in several locations in the Washington DC area including the National Arboretum, in the Marsden tract along the C&O canal, at Turkey Run Park, and at McKee Beshers Wildlife Management Area. I’ve also photographed it along the Blue Ridge Parkway in North Carolina and in the Great Smoky Mountains National Park in Tennessee.
