Donna, I haven't personally grown them in pots, indeed I can't recall ever seeing them in pots for sale in pots, but then they are easily grown in the ground here in a set and forgot fashion. Personally, with the depth and spacing requirements quoted here (4 inches deep, 8 apart) I would be putting 4 in a 12 or 14 inch pot, or singlely in an 8.
