Canna Lily (Canna × ehemanii) should be watered thoroughly, allowing the water to soak into the root zone—typically once a week is sufficient. During hot and dry periods, watering frequency may increase to twice a week. You should aim to provide about 1 to 1.5 gallons of water per week, depending on the size of the plant and the weather conditions. Always water at the base of the plant to avoid wetting the foliage, which can promote disease. Reduce watering in the fall as the plant prepares for dormancy.
Canna Lily thrives in full sunlight, needing at least 6 to 8 hours of direct sun daily. The best spot for this plant is an area where it can receive ample morning sunlight and some protection from the intense heat of late afternoon sun. Avoid placing it in full shade as it will not bloom as prolifically.
Canna Lily prefers a warm climate and does best in temperatures ranging from 60 to 90 degrees Fahrenheit. It can survive minimum temperatures of about 55 degrees Fahrenheit but should be protected from frost. The ideal growth temperature is between 70 and 85 degrees Fahrenheit. These plants are not hardy in cooler climates and should be lifted or protected in winter if temperatures fall below 55 degrees Fahrenheit.
Pruning Canna Lily is essential to encourage more blooms and maintain a tidy appearance. Deadhead spent flowers regularly to promote continuous blooming throughout the season. In late fall, after the first frost, cut the foliage back to a few inches above the ground as the plant goes dormant. Pruning is also the time to divide overgrown clumps, which can be done every few years.
Canna Lily prefers a rich, well-draining soil mix with a pH between 6.0 and 6.5. A good mixture could be equal parts of loam, peat, and sharp sand to ensure proper drainage and fertility.
Canna Lily should be repotted every 2 to 3 years or when the rhizomes outgrow the pot, typically in late winter or early spring before new growth begins.
- Humidity & Misting
Canna Lily thrives in high humidity levels, preferably between 60% and 70%, which is closer to its native tropical conditions.
- Suitable locations
Place in bright, indirect light, keep soil moist.
Plant in full sun, enrich soil, water regularly.
- Life cycle
Canna × ehemanii, commonly known as Eheman's canna, begins its life cycle as a rhizome planted just below the soil surface. In the germination stage, the rhizome develops roots and shoots that emerge from the soil as small green sprouts. The growth stage follows, where the plant produces large, paddle-shaped leaves and elongates its stems, taking weeks to a few months to reach maturity, depending on conditions. Following vegetative growth, it enters the flowering stage, usually in summer or early fall, generating striking red or pink blooms which attract pollinators. After pollination, seeds may form, though many varieties of canna are sterile hybrids and instead propagate through rhizome division. The plant may enter a dormancy stage in response to cooler temperatures or dry seasons, where the above-ground foliage dies back and the rhizome rests until favorable conditions return for the next growing season.
Canna Lily, which includes Canna × ehemanii, is typically propagated through the division of rhizomes, its most popular method. The ideal time to divide and propagate Canna Lilies is in the spring, just as new growth begins. To propagate, gardeners should carefully dig up the clump of rhizomes after the last frost has passed and the soil is warm. Using a sharp knife, they will cut the rhizomes into sections, ensuring each section has at least one eye, or growth point. These sections are then planted directly into the garden or pots, about 3 to 4 inches deep (approximately 7.5 to 10 centimeters) and spaced about 1 to 2 feet apart (30 to 60 centimeters). The soil should be kept moist but not waterlogged to encourage growth. After a few weeks, new shoots should emerge from the soil, indicating that the division has been successful.
