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.

You can estimate when it's possible to plant lobelia in Zone 12a by looking at the USDA zone info.

Planting Calendar for Lobelia

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

Since lobelia do well in cold you can plant them earlier in the year than more sensitive plants.

The earliest that you can plant lobelia 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 lobelia and expect a good harvest is probably November. Any later than that and your lobelia may not have a chance to grow to maturity. Starting your lobelia indoors is a great way to get them started a few weeks earlier.

Last Frost Date

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

Keep in mind that the actual date of last frost is just an average because it is based on the USDA zone info for Zone 12a and it changes from year to year. Since it never frosts in Zone 12a you do not have to be ready to protect your lobelia if you have a surprise late frost.
