David's Lily ( Lilium davidii )
The David - lily ( Lilium davidii ) (Chinese川 百合, Pinyin Chuan bǎihé ) is a species in the genus of lilies ( Lilium) in the section Sinomartagon. It is named after the French naturalist Armand David.
Description
The David - lily is a perennial, herbaceous plant that reaches the plant height of 60 to 200 centimeters. The bulbs are strong and round, they reach a diameter of 4.5 cm -6 cm. They are lanceolate with white, covered by Fox ovate scales, which change color red in air. The stalk is papillose and forms on the ground roots, sometimes he has a purple color impact. The lance-shaped leaves are up to 3.5 cm long and up to 1.5 cm wide. They are distributed around the stem, but focus on its center and are shorter than below at the top. The blade attachment is hairy.
It blooms two to three nodding flowers in July and August with a single flower or in a panicle. The stem is up to 1.25 m high, rarely up to 2 m. The hermaphrodite, threefold flowers have six degree recurved, up to 6 cm long, equally shaped bracts ( tepals ) with a glossy texture. The basic color of the flowers is orange to red with dark purple or black dots. The anthers are about 15 mm in size, the pollen is orange and light green filaments. The seeds mature up to 3.5 cm long capsule fruits. The seeds germinate instant- epigeal. The plant forms from numerous Wurzelbulbillen.
Dissemination
Originally the lily in the provinces of Gansu, Guizhou, Henan, Shanxi, Sichuan, Yunnan, widespread in the West of Hubei Province and in southern Shaanxi Province. As it is however cultivated as a food plant in a big way, they can now be found in almost all over the Peoples Republic of China and the Korean Peninsula. To what extent do these plants nor the wild form is debatable. David collected his plants in the district Moupin, Forrest in Tali Valley in Li- Chang Mountains and on the watershed between the Mekong and the Salween. The plant collector Ernest Henry Wilson described the David Lily in the valleys of the Min and Tung.
The David Lily needs a moist soil, often found on steep mountain slopes between grasses and small shrubs or boulders at which humus has accumulated, forest edges or on wet meadows at altitudes 800-3200 m above sea level, according to Fox between 1500-3000 m.
System
There are three varieties:
- Lilium davidii var davidii: Leaves einnervig, hairy white hairs in the leaf axils.
- Lilium davidii var wilmottiae: Central China, leaves three annoying leaf axils glabrous, curved stems, more flowers. The species is named after the patron of Wilson Ellen Willmott.
- Lilium davidii var unicolor: Southern Shanxi, up to 1 m high, flowers pale orange instead of red, less blotchy, purple spots (synonym L. sutchuenense )
Cultivation
With their starchy onion David's Lily is perhaps the most popular edible lily in China and is therefore widely cultivated. The lily is broken down into individual scales and these are usually fried in hot oil. Even dried lily scales are used. The strong color of the flowers and their shine are dominant in crosses, for this reason, the lily has been used repeatedly to breeding. The David lily was crossed for Preston, Northern and Patterson hybrids and the cultivar ' Fiesta' and present in most Asian varieties.
Cultural forms:
- Lilium davidii var macranthum: breeding by Raffil in Kew Gardens, up to 2 m high, orange flowers
- Lilium davidii ' Oriole ' by Preston
As a garden plant the lily David requires acidic soil, but also thrives on slightly calcareous soils, when a lot of humus contained in the soil. The onions can be attacked by Botrytis when the plants are too close.
