Tropicanna Black

The foliage of Canna Tropicanna® Black is a magnificent combination of purple shades blended with black. This is topped by the flowers - from Spring through to Fall - with blooms in rich scarlet-orange. When planted alongside with the original Canna Tropicanna® and Canna Tropicanna® Gold, the effect is astonishing.

Commercial landscapes in USDA zones 7 through 11 (no lifting required). It is ideal for planting in garden beds and borders and container plantings. Great for water gardens, ponds and bogs.

Growth Habit

Rhizomes bud and produce tall stalks that unfurl new leaf growth. A mass of flower buds develop a top mature stalks, blooming in succession

Plant Size

In garden beds: grows to 4-feet tall in the first year, grows up to 6-feet tall in subsequent years in zones 7 and above if not lifted after growing season. In containers: will grow up to 4-feet tall, can be cut back any time to force new growth. Plant in a large pot.


Cannas are tropical plants and are sensitive to extended exposure to frost. Mild winters (USDA zones 7 through 11): As soon as the leaves begin to die back, cut off foliage to soil level, and leave in-ground or in large containers over the winter. In spring, growth will start up as warmer temperatures arrive. Severe winters (USDA zones 3 through 6): As soon as the leaves begin to die back, cut off foliage to about 4 inches, dig up the rhizomes, let them dry for a few days in a protected area. Store the rhizomes in a cool dry place for the winter. Divide the rhizome shoots and replant in spring. Start indoors to get an early jump on the season, but do not put outside until all danger of frost is past.

Flowering Period

Bright scarlet/orange flowers (PMS 186C to PMS 164C) are produced from summer and then typically 2-3 months. Many flowers are produced during the season


Not fragrant.


Not necessary. Spent flower blooms drop naturally. Dig and divide to maintain size and shape.


Canna Tropicanna® Black is a tropical plant and should be protected from frost. Plants will over winter in the ground and withstand light frosts; however, potted plants will need to be protected or over wintered in a greenhouse. Canna Tropicanna® Black will start to grow when soil temperatures exceed 50ºF in Spring, but leaves won't attain full color until temperatures regularly exceed 60ºF.

Light Needs

Outdoors: Performs best in full sun (six hours of sun daily), but will tolerate partial shade (minimum four hours of sun daily). Indoors: best performance is achieved in a well-lit site with a minimum of 4 hours sun daily, with a summer vacation out of doors in a sunny or partial-shade position.

Soil Needs

Canna Tropicanna® Black tolerates a range of soils but will perform best in a deep fertile soil. It will tolerate poorly drained areas.

Water Needs

With masses of broad fleshy leaves, Canna Tropicanna® Black requires frequent watering to perform at its best.


In Spring, use a handful per plant of slow-release fertilizer

Disease Tolerance

Cannas are not prone to disease in the landscape

Pest Issues

No major pests.  Caterpillars can damage leaves.

Special Care

Avoid windy locations as the large soft leaves can be damaged. Outdoors: Easy care plant. Better performance will be attained if plants are watered and fed regularly, but once established, Canna Tropicanna® Black flowers readily with minimal care.
