Hi folks, once I plant a germinated canna seed in a proper sized pot, and assuming it gets plenty of water and sunshine, typically how long does it take before I'll see the first bloom?

I want to plant cannas in pots for the purpose of reselling them. No, I don't plan to get rich, we'll be selling these at a neighborhood function. Actually my daughter will be doing so. I'm just trying to determine when the best time to plant will be based on the amount of time it takes before one begins to bloom. I want to sell them once they begin to bloom (or shortly thereafter).

I know that with seeds you never know what you'll get, so I would assume the time to bloom is not the same with all cannas, but if I could get some ideas from folks who have grown from seed that would be awesome.

Thanks!

Chris
