The earliest that you can plant pennisetum in Zone 8b 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 pennisetum and expect a good harvest is probably August. Any later than that and your pennisetum may not have a chance to really do well. Starting your pennisetum indoors is a great way to get them started a little bit earlier.

Last Frost Date

The average date of last frost is March 15 in Zone 8b. It might get as low as 15°F during the coldest months of winter.

Always keep in mind that our actual date of last frost may not be accurate from year to year because it is based on the USDA zone info for Zone 8b and it is different every year. Half of the time in Zone 8b there is a last frost after March 15 so be sure to be ready to cover your pennisetum if we have a late frost.
