Before planting it is a good idea to find your USDA Zone info to figure out your garden schedule. The most important data that the zone info tells us is average last frost and the lowest expected temperature for your area.

In Montrose you can figure out when it's possible to plant aurinia by using the USDA zone info.

When to plant:	Up to 7 weeks before last frost.

Since aurinia do well in cold you can plant them a lot earlier in the year than more sensitive plants.

The earliest that you can plant aurinia in Montrose 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 aurinia and expect a good harvest is probably September. You probably don't want to wait any later than that or else your aurinia may not have a chance to grow to maturity. If you are starting your aurinia indoors then you might be able to get away with starting them a couple of weeks earlier.
