Since myosotis are one of those plants that can tolerate a little bit of cold weather you can plant them just a bit earlier in the year than other plants that might not handle the cold.

The earliest that you can plant myosotis in New Ulm is March. However, you really should wait until April if you don't want to take any chances.

The last month that you can plant myosotis and expect a good harvest is probably August. You probably don't want to wait any later than that or else your myosotis may not have a chance to fully mature. If you are starting your myosotis indoors then you might be able to get away with starting them a few weeks earlier.
