Outdoors grow in a sheltered site in fertile soil in full sun or semi-shade, planting in early summer once frosts have passed. Water freely in dry weather and apply a high potassium fertiliser monthly. Lift the rhizomes in autumn when frost blackens the foliage. Store over winter in barely moist peat-free potting mix or leaf mould in frost-free conditions. In mild areas leave in the ground but cover with a dry mulch. See canna cultivation
