Lilium candidum, the Madonna Lily is a well-known species with large waxy white trumpet-shaped flowers that have a sweet and very penetrating fragrance. It needs a shallow planting in a well-drained alkaline soil and the site should be prepared with the addition of generous quantities of sand, gravel and grit. Limestone chippings which can easily be bought from most garden centres are ideal to be added into the substrate to ensure alkalinity. A raised bed to ensure good drainage is perfect. It is planted earlier than most Lilies and develops its leaves over winter. Once established it is best left undisturbed. Like most lilies it will benefit from a sheltered position away from strong winds.
