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.

The first opportunity to plant evolvulus in Zone 12a should be determined by using the USDA zone info.

The last month that you can plant evolvulus and expect a good harvest is probably November.

Starting your evolvulus indoors is a great way to get them started a couple of weeks earlier.
