Canna Tropicanna® stands out from all the rest. The foliage is beautiful and exotic even without flowers, but it also blooms all summer long, until frost. It is great as a centerpiece in a landscape and is a good campanion to many sun loving plants. I plant them with dahlias and they look great. It is perennial for zone 8 and above but needs to be lifted to store indoors for zone 7 and below. I live in MN (zone 4B), and I can store them without much trouble, so you can too by following some easy procedures (many available in YouTube). It will reach 4' in the first year, and can reach 6' in the second year if you leave them in the ground, or you can dig up a big clump of rhizomes for winter storage. It also multiplies easily. Deer tend not to bother them. It loves sun, water and fertile soil.
