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 last month that you can plant myosotis and expect a good harvest is probably September. Any later than that and 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 couple of weeks earlier.
