One way of figuring out when you can plant bellis is to use the USDA zone info for Detroit.

The last month that you can plant bellis and expect a good harvest is probably September. If you wait any later than that and your bellis may not have a chance to really do well. You can get started a few weeks earlier by starting your bellis indoors.
