Magnolia sprengeri, or Sprenger's magnolia, is a species of Magnolia native to China, occurring in Gansu, Henan, Hubei, Hunan, Shaanxi, and Sichuan in forests or thickets at 1300–2400 m altitude. Named for Carl Ludwig Sprenger, a botanist of note.
It is a small deciduous tree, to 20 m in height with pale grayish brown to blackish brown, exfoliating bark. Young twigs are pale yellowish brown. The dark green leaves are obovate, 10–18 cm long and 4.5–10 cm broad, with a 1–3 cm petiole. Fragrant flowers appear before leaves, erect, cup-shaped, 15 cm wide, with 12-14 tepals that are white to rosy-red. The fruit is a cylindric aggregate of follicles 6–18 cm long.
Fossils of Magnolia sprengeri have been described from the fossil flora of Kızılcahamam district in Turkey, which is of early Pliocene age.[1]
It is grown as an ornamental tree for its flowers. Several cultivars have been named, including 'Diva', 'Lanhydrock', and 'Wakehurst'. The cultivars 'Burncoose',[2] 'Copeland Court',[3] and 'Eric Savill'[4] have all won the Royal Horticultural Society's Award of Garden Merit.
The species and its cultivars are hardy to roughly USDA hardiness zone 6. A number of hybrids with other Magnolias have also been developed.
