My spotted bee balm came up again this year, so I'm thinking that it's a perennial in zone 5, at least. It's about 10" tall, but it's not in full sun, either. I have it growing on the east side of the garage.

Great ahughes :)
Has it re-seeded for you at all?

Thanks

its very short lived plant.

and it grows pretty well in sunny and sandy soil zone 4. produces dense stands. as to the smell? i dont think its as powerful as fistulosa.

Here is a link that might be useful: horsemint

I'm not sure if what I have are re-seeds. I don't think they are, but I cannot be sure. April

Thanks...ahughes and Froggy,

As far as the smell goes...my fistulosa IS strong but what I'm saying leaves are not as pungently smelling while it is ready to bloom...right now the horsemint is smelling much stronger is all.
