Before planting it is a good idea to find your USDA Zone info to determine 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.

A common way of figuring out when it's possible to plant erysimum is to refer to the USDA zone info for Rutland.

Planting Calendar for Erysimum

Frost tolerance for erysimum:	Tolerant of some frost.
When to plant:	Up to 5 weeks before last frost.

Since erysimum are moderately cold tolerant you can plant them a bit earlier in the year than other frost tender plants.

The earliest that you can plant erysimum in Rutland 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 erysimum and expect a good harvest is probably September. If you wait any later than that and your erysimum may not have a chance to really do well. Starting your erysimum indoors is a great way to get them started a little bit earlier.
