Before planting it is a good idea to find your USDA Zone info to determine 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.

It's possible to estimate when it's the best time to plant pentas by using the USDA zone info for Zone 12a.

Planting Calendar for Pentas

Pentas do not do well in cold weather which means that you really should wait until it warms up after the last frost when the weather gets warmer before you can plant them.

The earliest that you can plant pentas in Zone 12a is January. However, you really should wait until February if you don't want to take any chances.

The last month that you can plant pentas and expect a good harvest is probably November. If you wait any later than that and your pentas may not have a chance to really do well. Starting your pentas indoors is a great way to get them started a couple of weeks earlier.

Last Frost Date

In Zone 12a it never frosts. In the coldest months of winter you can expect an average low temperature of 50°F.

Just be sure to remember that the actual date of last frost is not always accurate because it is based on the USDA zone info for Zone 12a and it is different every year. Since it never frosts in Zone 12a you do not have to be ready to cover your pentas if you have a surprise late frost.
