Plant the "Madeira" Canna in spring and it will bloom in mid summer through fall. Gardeners in areas that receive frost will want to dig the bulbs up at the end of the season and store them for the winter.
Growing Cannas, large and small. Canna lilies are wonderful in the garden. Growing fast, the full size selections quickly form a handsome large-leaved screen or an island of tropical-looking foliage from about 3 to 4 feet tall.. And then the show begins, and goes on for weeks and weeks. Huge, iris-like flowers begin to open, and before you know it, your canna lily plants have become the undisputed center of attention in your entire yard. They're really this spectacular, and a snap to grow. They're really wetland plants, and can grow in moist ground. Constant wetness isn't necessary, but water them often. Cannas are used as municipal plantings in many places like Miami. They are so good at taking care of themselves, they add great stripes of color in median strips, parks, and other places. So pick out a sunny spot in your garden or yard, and add cannas for the big show this summer.
Our good friend, Jack Scheper, the plant expert who runs Floridata.com, tells us that cannas are native to Central and South America, and many of the current hybrids also have a North American species as a parent. Jack grows cannas, and is a big enthusiast. As he says, the foliage "looks like a small banana tree without the trunk."
The Pfitzer Dwarfs Many gardeners prefer the smaller cannas of the "Pfitzer" group. With smaller, but brilliant, bi-colored flowers, these cannas grow to only about 16". They're great for the front of borders or patio pots, making a thick clump of handsome foliage with a bouquet that goes on all season.
