Canna durbans--also known as Tropicannas--are types of lilies that grow in USDA zones 7 to 10; however in colder zones, they need to be brought indoors during the winter months. Canna durbans have foliage that are a psychedelic mix of purple, green, gold and pink colors. Their flowers, which bloom from mid summer until fall, are a bright fiery orange color.
Like all lilies, canna durbans have bulbs for roots and should be planted as soon as you receive them, unless it is too cold. If it is too cold, store them in a cool dry place, such as a garage, until spring.
Select a location to plant your canna durbans in full sun or partial shade.
Amend your soil, if necessary. Canna lilies need well draining soil. Till in about two or three inches of compost or peat moss into 6 inches of soil. This will not only make your soil have better drainage, it will provide your lily with nutrients.
Dig a hole that is three times as wide as, but just slightly deeper than, the bulb. Space multiple plants at least 18 inches apart, however, canna durbans can reach a spread of 3 feet. Planting closer means the foliage will probably overlap, but that is fine.
Place the bulb into the hole with the point sticking up. Backfill the soil and tamp it down to fill in any air pockets. Water well.
Cover the planting site with 2-3 inches of mulch to help the canna durbans retain as much water as possible.
