Before planting it is a good idea to find your USDA Zone info to figure out your garden schedule. 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 figuring out when it's possible to plant saxifraga is to consult the USDA zone info for Key Biscayne.

The earliest that you can plant saxifraga in Key Biscayne 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 saxifraga and expect a good harvest is probably November. You probably don't want to wait any later than that or else 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.
