How to Collect Canna Seeds

The popularity of the tropical plants commonly called cannas (sometimes called canna lily) is no surprise to anyone who has ever grown these plants. From gnarled perennial rhizomes (not canna bulbs) emerge large leaves similar to bananas and gingers (sometimes colorful or stripped) and beautiful blooms in a variety of colors. When we gardeners in northern climates plant cannas in our gardens we usually plant the rhizome in the spring and summer and then lift it in the winter and store indoors. Propagating cannas is easy because all you need is a piece of the rhizome, but you can also propagate cannas from seeds if you know how to collect canna seeds.
