It has a minty fragrance and the leaves are used for making tea and are added to salads and jellies. The blooms have a colorful, shaggy appearance and can be planted in both the herb garden and perennial border.

Cut back plants periodically to keep them compact. Divide plants every 3 or 4 years; this will help control the rapid spread. For fall blooms, prune them back by to just a few inches above the ground after the first flowering.
- Mulching: Mulch bee balm in winter to protect roots from cold and snow.
Container growing monarda–bee balm

- When to harvest: Harvest leaves as needed. For the best flavor, harvest leaves before flower buds open.
- How to harvest: For drying in quantity, cut stems about one inch above the ground before bloom in early summer and again in late summer. Cut flowers for drying when blooms are almost fully open. Cut plants down to 1 inch of the ground after flowering; this will promote new growth and a second flowering.
