Planting & Growing

This plant is native to the tropics and prefers growing in moist environments with evenly warm conditions all year round. In our climate, it is usually grown as an outdoor annual in the garden or in a container. If you want it to survive the winter, it can be brought in to the house and provided with special care, and then returned to the garden the following season. In its preferred tropical habitat, it can grow to be around 5 feet tall at maturity, with a spread of 24 inches. However, when grown as an annual or when overwintered indoors, it can be expected to perform differently, and its exact height and spread will depend on many factors; you may wish to consult with our experts as to how it might perform in your specific application and growing conditions.

This plant should only be grown in full sunlight. It prefers to grow in moist to wet soil, and will even tolerate some standing water. It is not particular as to soil type or pH. It is highly tolerant of urban pollution and will even thrive in inner city environments. Consider applying a thick mulch around the root zone in winter to protect it in exposed locations or colder microclimates. This particular variety is an interspecific hybrid. It can be propagated by division; however, as a cultivated variety, be aware that it may be subject to certain restrictions or prohibitions on propagation.

Tropicanna Black Canna is a fine choice for the garden, but it is also a good selection for planting in outdoor pots and containers. With its upright habit of growth, it is best suited for use as a 'thriller' in the 'spiller-thriller-filler' container combination; plant it near the center of the pot, surrounded by smaller plants and those that spill over the edges. It is even sizeable enough that it can be grown alone in a suitable container. Note that when growing plants in outdoor containers and baskets, they may require more frequent waterings than they would in the yard or garden. Be aware that in our climate, most plants cannot be expected to survive the winter if left in containers outdoors, and this plant is no exception. Contact our experts for more information on how to protect it over the winter months.
