A genuine trumpet-type lily, even if the trumpet is wide-open and the petals strongly recurved. There are one to five drooping, pea-green
dark-purple within, loosely arranged on the , 4 feet tall, which also bears broad lanceolate . The bulb is flat and round, with broad, overlapping and tightly closed white scales, slightly tinged
with pink. The stem runs up to 5 feet underground, and forms bulb-lets on the internodcs before rising to the surface. A comparative late starter, which does not produce shoots until May, but nevertheless flowers during July.
L. nepalense is not winter-hardy in northern and central Europe, although it overwinters, without surface protection, in Scotland and Oregon. Surface protection from autumn and winter rains is necessary. This very exotic lily is a native of Nepal, Bhutan and Kumaon.
L. nepalense var. concolor originates from Assam, is self-coloured, yellow, and without the purple throat.
In spite of repeated endeavours, breeders have had little success in crossing this lily with other funnel-shaped types. The only reports are from Tuffery of New Zealand, who has produced hybrids with L. forntosanum, and from Palmer about Warburton hybrids arising from L. regale x L. nepalense x L. x anrelianensc. (RI-1S-LYB 1951-52, 1954, 1956, 1962; International Lily Register)
L. nepalense var. robustum. A recently introduced form with pendulous, strongly reflexed, emerald flowers with purplc-violet centres and of pleasing fragrance. It is said that this form is less susceptible to frost, and may even tolerate sub-zero temperatures. The stem runs underground
before rising to the surface, and the first growing shoots do not appear until May. Flowers during July/August, requires deep, very well-drained yet damp soil.
