According to Kew Gardens, it is from Central America and probably Cuba and Florida.   After going through the photos and labels for specimens in the SIEnet database, the only occurrences in Florida that were convincingly in natural systems (as opposed to highly disturbed areas) were on shell mounds, dunes, and similar coastal areas.  Hence, the range map provided highlights the counties along the west coast that have these. Noted as invasive  and weedy on many herbarium specimen labels.  Where not native, we should think of it as invasive.

Understory tree. Can be trimmed to keep sized as a shrub. Accent shrub or can be trained as a hedge.

If grown in a freshwater environment, S. patens will grow much bigger. Use as a shoreling stabilization plant on edges of sand beaches and saltmarsh.

Groundcover for moist to wet sites.

There is a natural dwarf form that is associated with xeric uplands.  I makes a nice, low-growing shrub in casual gardens. Good as a background or hedge plant that also attracts wildlife. Rain gardens or bioswales.
