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

Saxifraga can survive in very little cold which tells us that you can plant them slightly earlier in the year than plants that are more sensitive to the cold.

The earliest that you can plant saxifraga in Laredo 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 really do well. If you are starting your saxifraga indoors then you might be able to get away with starting them a little bit earlier.
