1) Roughly how much width do these dahlia plants take up?
2) Do they do well in pots, and if so, how wide and deep a pot would you use?
3) Do you think they'd do well planted among perennials like Black Eyed Susans, Catmint, Creopsis (Tickseed), Echinacea, etc.
4) Do you think the tubers could be planted in a bed we're seeding with sunny pollinator perennials?
