One of the first steps you take when you are getting a good idea your gardening schedule is find your USDA Zone info. The most important data that the zone info tells us is average last frost and the lowest expected temperature for your area.

One way of estimating when it's the best time to plant cleome is to use the USDA zone info for Zone 13a.

It's a bad idea to plant cleome until after the last frost when the weather gets warmer because they require warm weather.

The last month that you can plant cleome and expect a good harvest is probably November. If you wait any later than that and your cleome may not have a chance to grow to maturity. Starting your cleome indoors is a great way to get them started a few weeks earlier.

Last Frost Date

In Zone 13a it never frosts. You should expect an average low temperature of 60°F in the coldest months of winter.
