Common name: Giant lily, Spear lily, Gymea lily
Native to: New South Wales - Australia
An unusual plant which makes a striking addition to a large garden. Each plant grows from a thickened underground stem adnd forms a clump of numerous swod-like fibrous leaves ip to 1 metre in length and up to 10cm wide. Red, trumpet-like flowers, each about 10cm across, are borne in a compact terminal head. Suitable for large rockeries and gardens, D. excelsa makes an interesting foliage plant, but must be sited with care to ensure a well-drained, deep soil, in full sun or partial shade. An ideal position would be below an elevated patio where its tall flower spike can be appreciated. The plant needs to be kept well watered. In spring a small quantity of blood and bone or a slow release fertiliser should be applied.
