How to grow

Cultivation

As a patio plant grow in pots of loamless compost in a sheltered site in full sun. Plants can also be planted into a sunny border. Water freely and apply a high potassium feed every 2-3 weeks in the growing season. Lift the rhizomes in autumn when frost blackens the foliage. Store over winter in barely moist compost in frost-free conditions. See canna cultivation for further information

Propagation

Propagate by division of rhizomes in spring
