I've grown moonflowers for many years in a very large container. This year I want to grow moonflowers in small pots (about the size of a coffee can... actually exactly the size of a coffee can because that's what I'm planting them in). Is this sufficient space for moonflowers to spread their roots? In my experience, moonflowers have to grow really high up to bloom. I just want to make sure they'll grow enough to bloom.

Thanks in advance,

Anne
