In Sulphur you can figure out when to plant lunaria by reviewing the USDA zone info.

The last month that you can plant lunaria and expect a good harvest is probably September. If you wait any later than that and your lunaria may not have a chance to grow to maturity. If you are starting your lunaria indoors then you might be able to get away with starting them a couple of weeks earlier.
