One of the best tools that you have as gardeners to help us determine your gardening schedule is the USDA zone info. The most important data that the zone info tells us is average last frost and the lowest expected temperature for your area.

A way of figuring out when it's a good idea to plant myosotis is to examine the USDA zone info for Anamosa.

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 few weeks earlier.
