One of the best tools that you have as gardeners to help us figure out 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.

One way of figuring out when you can plant myosotis is to use the USDA zone info for Orinda.

Myosotis tend to make it in some cold which means that you can plant them a little bit earlier in the year than other frost tender plants.

The earliest that you can plant myosotis in Orinda is January. However, you really should wait until February if you don't want to take any chances.

The last month that you can plant myosotis and expect a good harvest is probably October. Any later than that and your myosotis may not have a chance to grow to maturity. Starting your myosotis indoors is a great way to get them started a little bit earlier.
