When to plant:	Up to 5 weeks before last frost.

You can plant erysimum just a bit earlier in the year because they do well in moderate cold.

The last month that you can plant erysimum and expect a good harvest is probably October. You probably don't want to wait any later than that or else your erysimum may not have a chance to really do well. If you are starting your erysimum indoors then you might be able to get away with starting them a little bit earlier.
