With brilliant flowers and giant leaves reminiscent of banana trees, cannas bring the feel of the tropics to temperate Philadelphia. They are not cold-tolerant enough to overwinter as perennials here in the Mid-Atlantic region, but if you dig up their rhizomes before the first hard frost, you can store them inside until spring, plant them, and expect another season of tropical glory in your garden.

Rhizomes have already been planted in potting soil: they will need to be transplanted, but have a head start because they’re already rooted.
