Likely more common than suggested by the known county occurrences as likely overlooked since its blooms are nocturnal. It is not clear to this author why anyone would seek out this plant except as a curiosity.  It begins blooming around 11 pm and the flowers are closed by 5 am. Useful as a curiosity in an aquatic garden as flowers open only late at night and closed by morning.

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. Informal wildflower garden in areas where it will not need to be handled.
