The earliest that you can plant salpiglossis in Tampa is March. However, you really should wait until April if you don't want to take any chances.

The last month that you can plant salpiglossis and expect a good harvest is probably September. Any later than that and your salpiglossis may not have a chance to fully mature. Starting your salpiglossis indoors is a great way to get them started a little bit earlier.
