Bright orange flower adds wow factor to any sunny location. Well worth overwintering in northern climates. Here's how:
When these plants die back, these underground structures can be dug and stored in a cool, dark place through the winter. The best time to dig the bulbs and tubers is after a light frost has killed the tops back. Trim the stems down to 4-6 inches and dig the plant up. Allow the tubers to dry slightly for a day or so before storing. Place the tubers in a crate or box with ventilation holes and bury the tubers in peat moss or wood shavings. You can bring a trash bag to your local hardware store where they cut the wood and ask them to empty their bin of saw dust.
Place the box in a cool (45-50 degree), dark area. Inspect the tubers regularly through the winter checking for rotting or excessive shrinkage. If tubers are drying out, add just a small amount of moisture to the peat. About 4-6 weeks before the last frost in the spring, pot the dormant tubers and place them in a warm, sunny area. This will give you a head start on having some tropical transplants for your garden.

This canna grows really well here without much care in 77580. The leaves are absolutely beautiful, and even if it never bloomed I would still grow it.

As we all know, C. 'Tropicanna' is a registered commercial name.

Its origins are in Africa and it was originally known as C. 'Phasion'.
Other names it is known by are: C. Andaloucia, C. Durban (Europe), C. Franciscus, C. Gold Ader, C. Inferno, C. Tiger Stripe, and C. Tropicana.

Serious canna collectors refer to this canna by its original name of 'Phasion.' They are not different cannas, but the same. They do not produce any viable seeds, being infertile, and the ONLY way to grow this canna is by rhizome divisions.

Tropicanna canna has such beautiful foliage, which really shows when the sun hits it.

In May 2018 a neighbor gave me a rhizome with an unfurling leaf. I planted it in a 12" pot on my patio so I could monitor its growth and spray it regularly with sevin to ward off caterpillars, which are real pests to cannas here in south Louisiana. It's late July and that starter plant is now 3 feet tall and has 4 different stems of leaf clusters that seem to be setting flower buds. Because it's been in morning sun only, it still has its deep vibrant coloring that would have faded in a full sun position. Best of all, the caterpillars never invaded it, so it's a picture perfect specimen. I will take pictures to post later.
