My grandmother raised this all the time (she was Cherokee). You can still get the seeds but have to look for the “old timey” ones. Not the newer ones. It will grow like a weed here in Texas.

flowering tobacco does well here but the humidity gets it. :( I love it and usually do some to sell at my greenhouse. Aphids love it. The new varieties don’t have near the smell that the old ones do.
