Pods contain numerous hard, brown seeds. The hard seed coat protects the seed embryo from water and enables dormancy. Germination can be induced by scarifying the seeds to allow water to penetrate the seed coat, and can be done by nicking the seed coat with a metal file or sandpaper.
TOXICITY AND ANIMALS Non-toxic to animals. (Dogs, cats, horses.)
COMMENTS Florida native found at the edges of marshes, ponds, and lakes, even the yards of households. Taller varieties may require a structure, such as a tomato cage for support. Cages are eventually covered with the foliage. Deadhead spent flowers for continuous blooms. Sensitive to cold and will freeze back to the roots during a freeze. Winter dormant. Can be propagated by thinning rhizomes (roots) after a few years by digging them up and replanting elsewhere. Golden Canna is self-fertile, so seeds can be produced by self-pollination, however some cultivars are sterile triploids and are unable to produce seeds. Pollinated by bats, hummingbirds, and other small wildlife.
