Canna

Coarse perennials that grow from a very large, thick, edible, underground rootstock.
The flowers on some varieties attract hummingbirds.
They prefer full sun on a fertile well drained soil. Heavily fertilization and a weekly heavy watering ( more often if extremely hot ) will definately encourage a lush plant. Removing spent blooms will encourage better foliage production and more bloom.
Hardy zones 7 to 11 unless otherwise noted. Cannas require well drained soil in winter ( even if wet in summer ) or the rootstock will rot if permanently wet while dormant. In zone 7 it should be mulched with pine branches.
In cold climates ( zone 6 and north ) remove rootstocks from the garden after the first autumn frost. Allow the roots to dry out in a warm place for a few days then store in slightly moist peat moss at temperatures above 40 F
The rhizomes transplant and divide easily in late autumn or early spring as long as dormant. They will also spread on their own by branching with a single plant eventually becoming a cluster of many plants.
Plant existing plants at the same depth and plant new tubers 3 to 5 inches deep and around 2 feet or more apart. Plants in patio planters and pots can be brought in and kept in the garage over winter then brought back outside in spring after the threat of frost has passed. Seeds should be soaked in water overnight before sowing.
