I started some plants in July last year, but they ended up becoming overwinters/early starts on this season. The later you start, the lower your expectations should be for getting ripe fruits off the plant. If you think you'll have the space indoors to overwinter them, then go for it, otherwise I'd say it's probably getting a bit late for the Canadian growers... even here, I would only think about starting annums at this point.
Just my 2 cents... I'm lazy/cheap, so I'm mainly concerned with getting pods during the growing season, I don't want to bother with any elaborate indoor grows.
