Before planting it is a good idea to find your USDA Zone info to figure out 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.

A way of getting a good idea when it's possible to plant violas is to use the USDA zone info for Grants.

Violas do ok in quite a bit of cold which means that you can plant them much earlier in the year than other frost tender plants.

The last month that you can plant violas and expect a good harvest is probably September. Any later than that and your violas may not have a chance to really do well. Starting your violas indoors is a great way to get them started a few weeks earlier.
