About
Lilium regale, called the regal lily, royal lily, king's lily,or, in New Zealand, the Christmas lily, is a species of flowering plant in the lily family Liliaceae, with trumpet-shaped flowers. It is native to the western part of Sichuan Province in southwestern China, and cultivated elsewhere as an ornamental. It was introduced to England in 1903 by Ernest Henry Wilson.
How to grow it
The Royal Horticultural Society has given Lilium regale its Award of Garden Merit. It is among the easiest lilies to grow in most temperate climate gardens. It tolerates most soils, except ones prone to waterlogging. It may naturalise in suitable conditions. It can also be grown in large containers. The bulbs themselves are very hardy, but the shoots appear early in the season and may be damaged by frost. Plants can be raised from seed, and often flower in their second year. A serious pest is the Scarlet Lily Beetle, the larvae of which may cause complete defoliation. Stems may require staking to support the large blooms.
There is a pure white form 'Album' which is also widely cultivated.
