Try looking for it using the botanical name: Calycanthus floridus. The cultivar 'Michael Lindsey' is especially fragrant.

Other common names for it include "sweetshrub" and "Carolina allspice".

It is native to the more northern parts of Florida.

I don't know how it will do that far south, but it's also easy to grow from seed. You might want to hit the exchange forum. Several people should have it. I just sent out the last of my seeds this morning.

It suckers as well, and can easily be propagated by removing one of the suckers.

I picked on up last spring at our local farmer's market for $3 in a gallon pot. Not sure if you have one where you live, I have had very good luck finding interesting plants at the market here (Gaston County)

Its also called sweet betsey bush. If you post on here someone might have it. Thats how i got mine. It did take me a while to find it. Its an old fashioned plant. Its also called carolina allspice and its a protected plant here in NC. hope that helps.

I planted one of these three years ago. It's about 4 feet tall now, but it still hasn't bloomed for me!
