One of the best tools that you have as gardeners to help us estimate your gardening schedule is the USDA zone info. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

You should be able to estimate when to plant saxifraga by looking at the USDA zone info for Zone 13a.

Saxifraga can survive in a tiny bit of cold which tells us that you can plant them slightly earlier in the year than other plants that might not handle the cold.
