We also have some gardeners that grow their native Southeast Asia produce, which do very well in our climate. Some gardeners are very adventuresome and try a couple of new crops each year. Last year one gardener grew sesame seeds, which did extremely well.
Some of the easiest and fastest growing vegetables are radishes. They do extremely well in the Texas heat. Tomatoes are some of the most difficult because of the weather fluctuations, bugs and diseases.
