Since romanesco are moderately cold tolerant you can plant them just a bit earlier in the year than more sensitive plants.

The last month that you can plant romanesco and expect a good harvest is probably October. Any later than that and your romanesco may not have a chance to fully mature. If you are starting your romanesco indoors then you might be able to get away with starting them a little bit earlier.
