Another significant discovery by E. H. Wilson, who first collected L. sargentiae in 1903 in the Tung valley in Szechwan, where it grows
between rocks on shale and among grass and scrub. The climate in this region is well known for its hot summers and long, cold winters.
The round bulb, 6 inches in diameter, has broad, red-purple scales. The, too, is purple, and grows 4-5 feet tall; it bears many dark-green, closely spaced, lanceolate – broader than those of L. regale -with bulbils in their axils. The large, funnel-shaped are pure-white within, have a yellow throat, and are shaded in cither purple-pink, brown or green on the outside. The rose tints on the outside of the petals are remarkable in so far as they even spread to the inside, and breeders have succeeded in emphasizing this characteristic in the Pink Trumpets. The plant carries up to 18 elegantly recurved and dcliciously fragrant blooms, which appear two weeks later than those of L. regale. Purple anthers, brown pollen, purple style and stigma. Multiplication by axil bulbils and ; germinate immediately; more delicate than L. regale; requires good , a warm location or a cool , and rich soil.
Crosses with L. regale (L. x imperiale), with L. henryi (L. x aurelian-ense).
