Since saxifraga are one of those plants that can tolerate a tiny bit of cold weather you can plant them a bit earlier in the year than other frost tender plants.

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

The last month that you can plant saxifraga and expect a good harvest is probably August. You probably don't want to wait any later than that or else your saxifraga may not have a chance to grow to maturity. Starting your saxifraga indoors is a great way to get them started a couple of weeks earlier.
