Datura tend to make it in a tiny bit of cold which means that you can plant them just a tiny bit earlier in the year than more sensitive plants.

The last month that you can plant datura and expect a good harvest is probably August. You probably don't want to wait any later than that or else your datura may not have a chance to grow to maturity.
