Canna lilies are very dramatic in the landscape; their light green stripes on broad, dark green leaves and the bright colors of the flowers, from orange to yellow to white, give them a tropical feel. Perfect for poolside, for accents, and tall enough to serve as summer borders, use canna lilies in your landscaping to make a statement.
Plant canna lilies by digging up the ground to about 12 inches deep; work in potting soil or organic compost, then place the bulbs so they are completely underground and the stem is just at soil surface.
Plant a row of canna lilies against a southern- or eastern-facing wall. The broad green leaves and bright flowers will pop out and their height, up to 6 feet, isn't overwhelmed by big structures.
Repeat the canna lily theme by adding them to a border or around trees. They'll die back in the winter, but they create a lush look and more privacy during the summer months when you spend more time outdoors.
Add another planting around the pool, patio, deck, or other outdoor seating area. Just be sure the spot you pick isn't water-logged, advises the University of Arizona Cooperative Extension Service. A group of these tropical flowers in hot orange or yellow really creates the feeling of an island escape.
Complete the canna lily landscaping by growing a group in a container and place it somewhere near the front door. Use pots or containers that are large enough to provide a counter balance to the height of the canna lilies, which grow from 3 to 6 feet. This will complete a circle in the landscaping, giving you continuity from the front to the back with the repetition of the canna lilies.
Dig up and divide canna lilies every two to three years; give away the extras or extend your landscaping by adding additional containers and plantings in borders, around trees, along fences and near benches or swings.
