Description

American Dittany is a fragrant native herbaceous perennial of the mint family. The genus name cunila is Latin for marjoram. The species names origanoides is from origanum which means "like oregano." Its common name, Dittany, comes from diktamnon which is the Greek name for a similar mint plant Origanum dictamnus, Dittany of Crete. American Dittany is found in the central and eastern parts of the United States. The flowers appear in small purplish lavender clusters that bloom from August to September.

The easiest way to propagate this plant is by stem cuttings in the spring and summer. Typically roots will form on the stem cuttings in about 7-10 days. The plant may also be easily divided in the summer. The plant attracts bees, butterflies, and skippers for nectar and for pollination. There are no known disease or pest issues. This plant is deer and drought tolerant.

American Dittany prefers dry and shallow rocky soil and full sun to part shade. They perform best as an interesting border plant and are a good option for native gardens, naturalized areas, herb gardens, or rock gardens. American Dittany's showy lavender flowers and fragrant green leaves in the early fall are a welcome contrast in color from the typical autumnal colors. During frosts in the fall, American Dittany may also form "frost-like" flowers which result from the bursting and freezing of exposed sap pushed out from its stems.
