Suggested Uses

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

Growth Habit

Dense clump-forming plant with horizontal subterranean rhizomes. Upright growth habit. Full mature height achieved in one season.

Growth Pattern

Annual rhizome development.

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 large pot, 15- to 18-inches in diameter or larger.

Spacing

Plant 18-inches apart in garden beds. Can be planted closer together in containers. Containers should be a minimum of 18-24inches diameter to promote optimal plant growth/size.

Hardiness

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 surrounded by wood chips if possible 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. May also be treated as an annual.

Flowering Period

Flowers all season long. Duration is typically 2 to 4 months. Many flowers are produced during the season.

Fragrance

Not fragrant.

Foliage

Grown primarily for its foliage color, each exotic leaf of Canna Tropicanna® Gold provides an enticing combination of green and gold stripes. A temperature greater than 60ºF is required for best leaf color. Leaves are a dark green to light yellow-green with alternating interveinal yellow-green stripes, which fade to creamy yellow as the plant matures. Interveinal stripes begin at the midrib of the blade and extend upwardly and outwardly towards the outer edges or tips of the leaves, with the shape and color of the stripes being irregular. Makes brilliant cut foliage.

Pruning/Pinching

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

Temperature

Canna Tropicanna® Gold 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® Gold will start to grow when 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 and a minimum night temperature of 58ºF with a summer vacation out of doors in a sunny or partially sunny spot

Soil and Water Needs

Canna Tropicanna® Gold will tolerate a range of soils but will perform best in a deep fertile soil. It will tolerate wet poorly drained areas. Frequent watering during hot dry spells is beneficial.

Fertilizer

In spring, use a handful per plant of slow-release flowering plant formula

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® Gold flowers readily with minimal care. In Containers: If a potted plant should dry out excessively, leaves may fade. If this should happen, cut back lackluster leaves or even the entire stem to the soil line. Water regularly. Plant will respond by sending up new shoots.
