General Comments:

There are two varieties in Florida which are essentially equivalent for landscape purposes:  Mimosa quadrivalvis var. angustata and M. quadrivalvis var. floridana. 

M. quadrivalvis var. floridana is predominantly found on the eastern side of the state and is almost endemic to the state. 

Between them, these two subspecies can be found almost throught mainland Florida.  As their ranges naturally overlapp, so it is unlikely that planting them where cross-pollination could occur would cause introgression between the two subspecies.
