Strawflowers can survive in some cold which means that you can plant them just a tiny bit earlier in the year than other plants that might not handle the cold.

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

The last month that you can plant strawflowers and expect a good harvest is probably August. Any later than that and your strawflowers may not have a chance to really do well. You can get started a little bit earlier by starting your strawflowers indoors.
