Choosing and combining
Cannas grow from rhizomes. Choose by foliage, flower colour and height: ‘Cleopatra’ has variegated leaves, while ‘Salmon Pink’ adds a softer shade. Check the current range.
Planting and position
Start rhizomes in warmth and light in spring, or plant outside once frost risk has passed. Provide fertile, well-drained soil and room to grow.
Care and overwintering
Keep soil moist during growth and provide suitable organic feed. Store rhizomes frost-free over winter; a leaf mulch alone does not protect against hard frost. Divide in spring if needed.
