One of the best tools that you have as gardeners to help us estimate your gardening schedule is the 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.

By using the USDA zone info for Zone 13a you should be able to figure out when it's a good idea to plant rudbeckia.

Planting Calendar for Rudbeckia

Frost tolerance for rudbeckia:	Tolerant of some frost.
When to plant:	Up to 5 weeks before last frost.

Rudbeckia can survive in mild cold which tells us that you can plant them a little bit earlier in the year than other plants that might not handle the cold.

The earliest that you can plant rudbeckia in Zone 13a 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 rudbeckia and expect a good harvest is probably November. You probably don't want to wait any later than that or else your rudbeckia may not have a chance to really do well. Starting your rudbeckia indoors is a great way to get them started a few weeks earlier.

Last Frost Date

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

It's important to remember that the actual date of last frost may not be accurate from year to year because it is based on the USDA zone info for Zone 13a and it can change quite a bit from year to year. Since it never frosts in Zone 13a you do not have to be ready to cover your rudbeckia if you have one of those late frosts.
