You should be able to determine when to plant nemesia by looking at the USDA zone info for Gary.

Planting Calendar for Nemesia

Frost tolerance for nemesia:	Not tolerant of frost.
When to plant:	After all chance of frost has passed.

It's probably a bad idea to plant nemesia until after the last frost has passed because they do not do well in cold weather.

The earliest that you can plant nemesia in Gary is April. However, you really should wait until May if you don't want to take any chances.

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