I have Cannas beside mine and they look really good, especially the yellow ones. I thought about getting different kinds of gingers as well. I bought some Pink China elephant ears that are hardy to zone 6, maybe 5 with lots of mulch ( supposed to be the hardiest elephant ear there is) but kinda wondering if they might push the bananas around. I have three plants in small pots, and they have already made 3 more baby plants in 1 week. I might wait to put them around the Bananas when the Bananas are much, much taller.
