Teresa,
@bluegrassmom you've heard right, they are very hungry, thirsty beasties, but will pay you back for all the feeding and water with robust growth and more bloom cycles per season. They love rich soil, mulch and it's a good idea to hose the leaf canopy once in a while if you get a run of hot, dry weather because spider mites love them. They don't seem to invade if you just hose the plants down regularly.
Mine often go right through winter blooming about every month to 6 weeks in cycles. I prune them when needed to keep down to a reasonable size, always after a bloom cycle is just finished. They're in full sun through the winter, but get shaded nicely from the midday sun in the hot months. Full sun in Florida . . . what can I say, it's brutal.
I'd suggest for winter, just take some cuttings, and bring them indoors to grow on your windowsill. They root very readily from cuttings, and will grow fairly slowly if you give them a cool spot near a sunny window. Then you'll have plants ready to rock when it warms up enough in the springtime.
