Grow under glass from corms in autumn. Plant into John Innes No 2 compost and grow on in full light. Apply a weak, balanced liquid fertiliser every 3 weeks before flowering. Dry off as the leaves die down in summer. Corms can also be bought in spring for planting outside for a one off summer blooming, but after this, would need to be grown under glass and allowed to winter grow. Plant corms 15cm (6in) deep
