The USDA zone info for Eureka should be reviewed to estimate when it's a good idea to plant saxifraga.

When to plant:	Up to 3 weeks before last frost.

You can plant saxifraga a bit earlier in the year because they are barely cold tolerant.

The earliest that you can plant saxifraga in Eureka 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 grow to maturity. If you are starting your saxifraga indoors then you might be able to get away with starting them a little bit earlier.
