I am sorry for this delayed reply to your gardening question. The spring rush has brought a deluge of questions and we are working hard to catch up!
Whiteflies are already in most of the southern U.S. They attack some crops and ornamental plants but not by any means all. Go ahead and grow what you want. When they show up on a crop or plant we or someone else can make a suggestion for the best control options for that particular plant. In many cases it is something as safe as insecticidal soap, vegetable based summer oils, or the natural product neem.
Thanks for the question. Best wishes for a wonderful gardening season. Please stop in again soon!
