Plant Type
Rhizomatous perennial
Canna × ehemanii is a tropical hybrid perennial known for its large, lush green leaves and graceful, drooping pink flowers. A member of the canna lily family, it adds bold, exotic charm to garden beds, ponds, or containers, flourishing in warm climates with rich soil and consistent moisture.
Mature Height
120–180 cm tall (about 4–6 feet)
Canna × ehemanii typically grows 120–180 cm tall (about 4–6 feet). The sturdy, upright stems and broad, banana-like leaves create a dense, dramatic clump, while arching flower stalks rise above the foliage to display its pendant blooms, making it a standout feature in tropical or subtropical gardens.
Light Requirements
Partial shade – Full sun
This canna thrives best in full sun, receiving at least six hours of direct sunlight daily. It tolerates partial shade but may produce fewer flowers. Bright, open positions promote vigorous foliage, stronger stems, and abundant blooms, making sunlight a key factor in achieving its most vibrant growth.
Water Requirements
Moderate
Canna × ehemanii enjoys consistently moist, rich soil. It tolerates wet conditions and even shallow water but dislikes drying out. Regular watering, especially during warm weather, helps maintain lush foliage. Avoid waterlogging in containers by ensuring good drainage while keeping the soil evenly damp throughout the growing season.
Cold Hardiness
-7°C (20°F)
Canna × ehemanii is hardy to about -7°C (20°F), suitable for USDA Zones 8–11. In regions with colder winters, rhizomes should be lifted after the first frost and stored in a cool, dry place. Frost damages foliage, but protected rhizomes resprout vigorously once temperatures warm in spring.
