Hello!

I wondered if someone could tell me if Amaranthus will handle being potted? I read that it likes full sun and dry-ish soil but can't find any further info about potting. I though it would look incredible trailing out of hanging baskets or tall classical urns.

If you have potted it with success, what did you plant with it? I was considering something chartreuse like a sweet potato vine and maybe some deep purple pansies. :)
