How to grow
Cultivation
Grow in a sheltered site with full sun. Water freely in dry spells and apply a balanced liquid feed monthly. In cold regions, lift the rhizomes in autumn once frost has blackened the foliage and store in barely moist compost in frost-free conditions. In areas that are frost-free or almost so, leave in situ and protect with a deep dry mulch. See canna cultivation for further information
Propagation
Propagate by division of rhizomes in spring
