African lily

- Soil: fertile, moist, well-drained soil (or John Innes no. 3 compost for containers)
- Rate of growth: average
- Flowering period: July to September
- Hardiness: frost hardy (may need some protection in winter)
Tolerant of drought, this decorative perennial produces large heads of pale, grey-blue flowers from mid-to-late summer. It makes a fine specimen in a pot, where its architectural silhouette can best be appreciated, or dot it through the summer border. - Garden care: Apply a balanced liquid fertiliser monthly from spring until flowering. In cold areas, protect the crown of the plant with a deep, dry mulch to protect them from hard frosts, or grow in a pot so they can be overwintered in an unheated greenhouse. Divide plants in spring. Divide plants that have become too big in spring, but remember you will often get more flowers when the roots are constricted.
