In Urbana you can estimate when to plant lunaria by referring to the USDA zone info.

Lunaria do well in some cold which means that you can plant them just a bit earlier in the year than plants that are more sensitive to the cold.

The last month that you can plant lunaria and expect a good harvest is probably September. You probably don't want to wait any later than that or else your lunaria may not have a chance to really do well. You can get started a couple of weeks earlier by starting your lunaria indoors.
