One of the first steps you take when you are figuring out your gardening schedule is find your 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.

One way of estimating when you can plant saxifraga is to look at the USDA zone info for Los Fresnos.

The last month that you can plant saxifraga and expect a good harvest is probably September. Any later than that and your saxifraga may not have a chance to fully mature. If you are starting your saxifraga indoors then you might be able to get away with starting them a little bit earlier.
