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.

You should be able to figure out when it's possible to plant myosotis by using the USDA zone info for Berne.

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 means that you can plant them a little bit earlier than other frost tender plants.

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

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 really do well. Starting your myosotis indoors is a great way to get them started a couple of weeks earlier.
