Before planting it is a good idea to find your USDA Zone info to determine your garden schedule. 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 determine when you can plant violets by looking at the USDA zone info for Zone 1a.

Planting Calendar for Violets

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

Violets can survive in mild cold which tells us that you can plant them a little bit earlier in the year than other plants that might not handle the cold.

The earliest that you can plant violets in Zone 1a is May. However, you really should wait until June if you don't want to take any chances.

The last month that you can plant violets and expect a good harvest is probably July. Any later than that and your violets may not have a chance to fully mature. Starting your violets indoors is a great way to get them started a couple of weeks earlier.

Last Frost Date

On average the last frost has passed is on June 15 in Zone 1a. It might get as low as -60°F during the coldest months of winter.

It's important to remember that USDA zone info for Zone 1a may not be accurate from year to year and the actual date of last frost can change quite a bit from year to year. Half of the time in Zone 1a you get surprised by a frost after June 15 so always be ready to cover your violets if you have a late frost.
