One of the first steps you take when you are estimating your gardening schedule is find your USDA Zone info. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

One way of estimating when you can plant crossandra is to look at the USDA zone info for Zone 11b.

Planting Calendar for Crossandra

Frost tolerance for crossandra:	Not tolerant of frost.
When to plant:	After all chance of frost has passed.

Crossandra do not do well in cold weather which means that you have to 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 crossandra in Zone 11b 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 crossandra and expect a good harvest is probably November. You probably don't want to wait any later than that or else your crossandra may not have a chance to grow to maturity. Starting your crossandra indoors is a great way to get them started a couple of weeks earlier.

Last Frost Date

In Zone 11b it never frosts. In the coldest months of winter you should expect an average low temperature of 45°F.

Since the USDA zone info for Zone 11b may not be accurate from year to year the actual date of last frost will vary from year to year. Since it never frosts in Zone 11b you do not have to be ready to protect your crossandra if you have a late frost.
