One of the best tools that you have as gardeners to help us determine 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.

You can determine when it's possible to plant flower-of-an-hour in Zone 13a by reviewing the USDA zone info.

Planting Calendar for Flower-of-an-Hour

Frost tolerance for flower-of-an-hour:	Tolerant of a very small amount of frost.
When to plant:	Up to 3 weeks before last frost.

Flower-of-an-Hour do ok in moderate cold which means that you can get them planted just a bit earlier than plants that are more sensitive to the cold.

The earliest that you can plant flower-of-an-hour 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 flower-of-an-hour and expect a good harvest is probably November. You probably don't want to wait any later than that or else your flower-of-an-hour may not have a chance to grow to maturity. You can get started a couple of weeks earlier by starting your flower-of-an-hour indoors.
