The earliest that you can plant saxifraga in Wood River 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 few weeks earlier.
