The climate in South Florida can be a challenge for many vegetables. Many imported tropical varieties prefer higher altitude. On the other hand, many vegetables that tolerate dry heat cannot tolerate the humidity in South Florida.
This books should be helpful. I bought the older, first edition, from Amazon:
The Art of South Florida Gardening: A Unique Guide to Planning, Planting, and Making Your Subtropical Garden Grow Paperback by Harold Songdahl (Author), Coralee Leon (Author), George Curtis (Illustrator)
