In Jackson you can determine when to plant romanesco by reviewing the USDA zone info.

Planting Calendar for Romanesco

Since romanesco do well in moderate cold you can plant them just a bit earlier in the year than plants that are more sensitive to the cold.

The earliest that you can plant romanesco in Jackson is January. However, you really should wait until February if you don't want to take any chances.

The last month that you can plant romanesco and expect a good harvest is probably October. You probably don't want to wait any later than that or else your romanesco may not have a chance to really do well. Starting your romanesco indoors is a great way to get them started a few weeks earlier.
