Before planting it is a good idea to find your USDA Zone info to figure out your garden schedule. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

A common way of determining when it's the best time to plant pansies is to use the USDA zone info for Herrin.

Planting Calendar for Pansies

Frost tolerance for pansies:	Very tolerant of frost.
When to plant:	Up to 7 weeks before last frost.

Since pansies do well in cold you can plant them a lot earlier in the year than more sensitive plants.

The earliest that you can plant pansies in Herrin 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 pansies and expect a good harvest is probably September. You probably don't want to wait any later than that or else your pansies may not have a chance to grow to maturity. If you are starting your pansies indoors then you might be able to get away with starting them a little bit earlier.

In Herrin the average date of last frost happens on April 15. It might get as low as -5°F during the coldest months of winter.

Since the USDA zone info for Herrin is not always accurate the actual date of last frost can change quite a bit from year to year. Half of the time in Herrin there is a last frost after April 15 so always be ready to protect your pansies if you have one of those late frosts.
