Before planting it is a good idea to find your USDA Zone info to figure out your garden schedule. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

In Austin you can figure out when to plant myosotis by using the USDA zone info.

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 really do well. If you are starting your myosotis indoors then you might be able to get away with starting them a couple of weeks earlier.
