One of the best tools that you have as gardeners to help us estimate your gardening schedule is the USDA zone info. The most important data that the zone info tells us is average last frost and the lowest expected temperature for your area.

One way of figuring out when it's the best time to plant coleus is to refer to the USDA zone info for Parsons.

Planting Calendar for Coleus

It's a bad idea to plant coleus until after all chance of frost has passed because they do not do well in cold weather.

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