In Florence you can estimate when to plant saxifraga by using the USDA zone info.

Planting Calendar for Saxifraga

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

Since saxifraga are barely cold tolerant you can plant them just a tiny bit earlier in the year than more sensitive plants.

The earliest that you can plant saxifraga in Florence is February. However, you really should wait until March if you don't want to take any chances.

The last month that you can plant saxifraga and expect a good harvest is probably September. You probably don't want to wait any later than that or else your saxifraga may not have a chance to fully mature. You can get started a couple of weeks earlier by starting your saxifraga indoors.
