When I look up Tampa USDA Zone it says it is zone 9B. I live in zone 10B and they do well in full sun here. My focus then moved to heat and rain. If the brug is a good size (3-4 feet) I would think it would so well in the ground with your watering schedule. The rain should be ok as well if it is in the ground. A pot might promote root rot... that is my 2 cents..
Hopefully we have someone who lives in Fl. to answer more directly.
