By using the USDA zone info for Woodland you should be able to figure out when it's possible to plant canna.

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