This perennial is semi-evergreen so it can lose some of its leaves in winter. In colder regions or more exposed gardens, it may lose them all, but then fresh new growth appears again in spring.

• Position: full sun
• Soil: fertile, moist, well-drained soil (or John Innes no. 3 compost for containers)
• Rate of growth: average
• Flowering period: July to August
• Hardiness: frost hardy (may need protection in winter)
  
  Globes of deep blue-black, trumpet-shaped flowers burst from almost black buds in July and August above semi-evergreen, strap-like leaves. This stunning African lily is perfect for the middle of a sunny, moist but well-drained border or a large patio pot. Although hardier than other varieties, in cold, exposed areas container-grown specimens will benefit from a deep, dry winter mulch.
  
  
• Garden care: Keep well-watered during the growing season, applying a balanced liquid fertiliser each month from spring until the plant flowers. Towards the end of September ease back on the watering and feeding of plants in containers to allow the foliage to toughen up. In cold, exposed areas protect the crown of the plant with a deep, dry winter mulch.
