The last month that you can plant violets and expect a good harvest is probably July. You probably don't want to wait any later than that or else your violets may not have a chance to really do well. If you are starting your violets indoors then you might be able to get away with starting them a couple of weeks earlier.

Last Frost Date

In Zone 1b the average date of last frost happens on June 15. It might get as low as -55°F during the coldest months of winter.

It's important to remember that our actual date of last frost is an average because it is based on the USDA zone info for Zone 1b and it changes from year to year. Half of the time in Zone 1b we get surprised by a frost after June 15 so just be sure to be ready to cover your violets if we have a surprise late frost.
