In Somerville you can determine when it's a good idea to plant myosotis by reviewing the USDA zone info.

Planting Calendar for Myosotis

When to plant:	Up to 5 weeks before last frost.

Since myosotis are moderately cold tolerant you can plant them a little bit earlier in the year than other frost tender plants.
