Platycodon do well in a tiny bit of cold which means that you can plant them slightly earlier in the year than more sensitive plants.

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