Bee balm typically blooms from midsummer to fall. Most varieties begin blooming around July and continue through late summer. Some types, like horsemint (a native bee balm), can start blooming as early as May and continue until October. The bloom duration can be extended by deadheading spent flowers regularly. Depending on the variety, bee balm's flowering period generally begins in June or July and lasts until October. In certain regions, it may even bloom from late May through August or into early fall. In summary:
- Typical bloom start: July
- Extended bloom period: May to October (depending on variety)
- Bloom lasts through late summer into early fall
- Deadheading helps maintain longer blooming.
