Before planting it is a good idea to find your USDA Zone info to figure out your garden schedule. The most important data that the zone info tells us is average last frost and the lowest expected temperature for your area.

In Tallahassee you can estimate when it's possible to plant datura by referring to the USDA zone info.

Planting Calendar for Datura

Frost tolerance for datura:	Tolerant of a very small amount of frost.
When to plant:	Up to 3 weeks before last frost.

Since datura are barely cold tolerant you can plant them a bit earlier in the year than plants that are more sensitive to the cold.

The earliest that you can plant datura in Tallahassee 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 datura and expect a good harvest is probably August. Any later than that and your datura may not have a chance to grow to maturity. If you are starting your datura indoors then you might be able to get away with starting them a little bit earlier.

Last Frost Date

Since the USDA zone info for Tallahassee may not be accurate from year to year the actual date of last frost changes from year to year. Half of the time in Tallahassee there is a last frost after March 15 so always be ready to cover your datura in the event of one of those late frosts.
