I'm not sure it acts the same in your Florida conditions as it does here in California. It comes from the subtropical summer rainfall areas of South Africa, but probably mostly occurs at higher elevations in the mountains where the heat and humidity is not as extreme as it is in Florida. Here in California it typically does start blooming in fall with shorter day length, and will continue into spring in southern California, but typically stops blooming with onset of colder weather in late December here in the San Francisco Bay Area. It is very prone to growing long floppy stems, and benefits from being tip pinched to promote bushiness several times after it finishes blooming. Of you could plant lower growing shrubs around it to help support the stems if you prefer to let it get tall. It is also very easy to start from new cuttings, and is a somewhat short lived perennial shrub in my opinion, that is best replaced with new ones after 3 to 4 years of growth.
