The USDA Zone info is a great tool for gardeners to help us determine your gardening schedule. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

One way of determining when you can plant myosotis is to use the USDA zone info for Zone 2b.

Planting Calendar for Myosotis

Frost tolerance for myosotis:	Tolerant of some frost.
When to plant:	Up to 5 weeks before last frost.

Myosotis do well in moderate cold which tells us that you can start planting them earlier than other frost tender plants.

The earliest that you can plant myosotis in Zone 2b is April. However, you really should wait until May 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 really do well. If you are starting your myosotis indoors then you might be able to get away with starting them a little bit earlier.

Last Frost Date

In Zone 2b the average date of last frost happens on May 15. In the coldest months of winter you should expect an average low temperature of -45°F.

Always keep in mind that USDA zone info for Zone 2b is not always accurate and the actual date of last frost is different every year. Since half of the time in Zone 2b you get a frost after May 15 be ready to cover your myosotis if you have one of those late frosts.
