Canna Lily: How to Plant, Grow, and Care for Canna Flowers

Cannas are among the most colorful summer bulbs—as flamboyant as their tropical American ancestry—with ruffled spikes tapering to refined buds.The gorgeous canna boasts immense, often-veined, paddle-shaped leaves and sheathing leafstalks in shades of green or bronze—and flashy blooms that stand tall on their stems.Or, make cannas the focus and hero of large patio pots filled with super bright annuals. .

How to Grow Cannas - Canna Lily

These lush tropical plants produce large — sometimes colorful — leaves, and tall flower stalks with vibrant blossoms.Dwarf varieties look great in large containers combined with petunias, sweet potato vines, and other low-growing annuals.Larger varieties make a strong, elegant statement planted at the back of flower beds or grouped together in showy islands of color.For earlier flowers, cannas can be planted in pots and started indoors or in a greenhouse about one month before mild weather arrives. .

How to Grow Cannas

Cannas, with their big, brightly-hued flowers and banana tree leaves look like they spring straight from the tropics, but there are actually several species native to the United States.Rainbow colored leaves and/or nonstop blooms of cannas add ambience to poolside plantings and brilliant splashes to home gardens.Sometimes called bulbs, cannas actually grow to heights of up to eight feet in one season from rhizomes, or underground stems.They will also grow equally well in large containers that can be dragged inside during the dormant period.If you want some extra privacy for the backyard during the summer, plant cannas as a temporary (non-evergreen) screen.Trimming & Pruning: Deadhead regularly to prevent plants from setting seed, which will prolong bloom.In zones 7-10, add another layer of mulch in the fall to protect rhizomes from the cold as the plants overwinter in place.Cannas: End of Season Care After a hard frost, cut plants back to the ground.Spread a 3 inch layer of mulch or composted leaves on top of rhizomes.To lessen the chance of fungal infection, allow the divided rhizomes to dry and heal for a few days before planting.Halt their damage by regularly spraying plants with Bacillus thuringiensis (an organic soil bacterium that works as a pesticide) during the growing season. .

Spoil your cannas with the richest soil, like Monty Don does

In fact, most problems with growing cannas come from cold temperatures as they are not really hardy and, except in the very warmest spots of Britain, I always recommend lifting them and storing the plants in a frost-free place over winter.Conventional gardening wisdom has it that cannas need lots of water – and certainly they will grow quite happily in a bog or even submerged in the margins of a pond.The soil of our Jewel and Cottage Gardens is a marvellous clay loam to start with and then has had a quarter of a century of me piling on compost and manure.The combination of their vivid, flamboyant flowers and enormous, striking foliage makes cannas one of the most dramatic plants in any garden.‘Australia’ is enormous – my specimens are certainly too big for the pot I first planted them in – but is perfect at the back or centre of a large border to up the ante when it comes to pure extravagant lushness.John Haran, Yorkshire A It sounds as though the plant has suffered while being left unwatered over your holiday in extreme heat.Hydrangea cuttings can take a few years to bloom, however, and a really cold snap will kill the flower buds that have formed the previous autumn, so it may be a combination of these factors.Sue Allen, Essex A Buddleias originate from the sides of hills in the southern Himalayas and have evolved to thrive in very poor, free-draining, stony soil.Canna roots are fleshy and store enough food to take the plant through its dormant winter season but they must not be allowed to dry out.Although by no means the largest of the red-hot pokers, it will grow to more than a metre tall, with its strong stems topped by orange and yellow flowers. .

How to Leave Cannas Out All Winter

For wet areas, select cannas from the aquatic group.These moisture-loving plants work well water features, ponds and bogs. .

Canna Lily: Plant Care & Growing Guide

Botanical Name Canna Common Name Canna, canna lily Plant Type Flowering perennial (annual in colder zones) Mature Size 1 1/2– 8 feet tall, 1 1/2–6 feet wide Sun Exposure Full sun Soil Type Rich, moist, well-draining Soil pH 6.0 to 6.5 (slightly acidic) Bloom Time Summer Flower Color Red, orange, yellow, pink, cream, white; solid color or with contrasting spots ​Hardiness Zones 7 to 10 ( USDA); rhizomes must be dug and stored over winter in colder climates Native Areas South America, Central America, West Indies, Mexico, southeastern United States.In colder climates, after the first frost in fall, cut the canna back to the ground.Carefully dig up the rhizome clumps and store them through the winter in peat moss or vermiculite in a location that doesn't fall below 40 degrees Fahrenheit.Spray the rhizomes with water infrequently to prevent them from drying out, but don't allow them to sit in a consistently damp medium.They are also generally resistant to pest problems, although you might find caterpillars or grasshoppers eating the leaves—remove them by hand.Feed monthly throughout the growing season, starting in the early spring, with a balanced fertilizer.'King Humbert': an older variety with dark bronze-purple foliage and large red to orange-red flowers.produces orange flowers with leaves striped with burgundy, gold, yellow, pink, and green 'Pretoria' ('Bengal Tiger'): bicolored orange flowers and yellow and green striped foliage.Cannas generally do not need pruning, but deadheading the flowers (once they have faded) will produce more blooms.Choose a container that is no smaller than 16 inches in diameter with adequate drainage holes.Make sure the container has good drainage, and fill it with quality potting soil.Because cannas are heavy feeders, mix some slow-release fertilizer into your potting soil before you plant.Slugs, snails, and Japanese beetles delight in chewing holes in canna leaves and flowers.Remove a leaf if you see that it's unable to unfurl, and consider spraying the plant with insecticidal soap if pests are present.But with canna mosaic virus and aster yellows, you often have to dispose of the entire plant. .
