This plant is classified as an annual, biennial and perennial according to the USDA Plant Database. In my own yard, it does reseed and I have new plants coming up around the parent plant which so far has been perennial for the last 3 years.
This native plant prefers medium to dry, well drained soils in a sunny location. It is related to the Wild Bergamot (Monarda fistulosa) but quite unlike the Bergamot in appearance. It does extremely well on our sunny gravel slope. The flowers are quite unique, flowering from the bottom upwards on the flower stem in whorled layers.
The whorled leaves below the flowers are white to pink in color and the flowers are an interesting light yellow speckled with rusty red. The plant for me resembles a pineapple with its upward pointing leaves at the growth tip.
A large clump of this native stands out amongst prairie forbs and grasses with its light colored leaves. In the evening and under moonlight it glows. Spotted Bee Balm flowers from mid July through September.
Spotted Bee Balm is native to south and eastern North America. Link to USDA map.
