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.

One way of estimating when you can plant alyssum is to consult the USDA zone info for Zone 13a.

Planting Calendar for Alyssum

Frost tolerance for alyssum:	Very tolerant of frost.
When to plant:	Up to 7 weeks before last frost.

Alyssum tend to make it in a bit of cold which tells us that you can plant them earlier in the year than other plants that might not handle the cold.

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

Last Frost Date

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

Since the USDA zone info for Zone 13a is not always accurate the actual date of last frost will vary from year to year. Since it never frosts in Zone 13a you do not have to be ready to cover your alyssum in the event of a surprise late frost.

USDA Zone Info for Zone 13a

Here is the info for USDA Zone 13a.

Average Date of Last Frost (spring)	Never
Average Date of First Frost (fall)	Never
Lowest Expected Low	60°F
Highest Expected Low	65°F

This means that on a really cold year, the coldest it will get is 60°F. On most years you should be prepared to experience lows near 65°F.
