You can estimate when to plant erysimum in Chanhassen by using the USDA zone info.

The last month that you can plant erysimum and expect a good harvest is probably August. Any later than that and your erysimum may not have a chance to grow to maturity. You can get started a couple of weeks earlier by starting your erysimum indoors.
