Magnolia campbellii in Trengwainton Garden, Cornwall

Magnolia campbellii is a medium-sized to large deciduous tree growing to 30 m, rarely to 45 m, tall, with smooth grey bark. The leaves are 10-23 cm (rarely to 33 cm) long and 4.5-10 cm (rarely to 14 cm) broad, fuzzy underneath and with an acute apex. The flowers are very large, 15-25 cm (rarely 35 cm) diameter, with 12-16 tepals, which vary from white to dark pink. They appear very early, before the leaves, opening from late winter to early spring. After opening, the innermost tepals remain erect while the others spread widely. This arrangement may shelter the stamens and stigmas from rain, snow, and other harsh environmental conditions common during their very early flowering time period.

Varieties

There are two varieties:

  • Magnolia campbellii var. campbellii. Western part of the species' range, in the Himalaya. Shoots and flower stalks thinly hairy.
  • Magnolia campbellii var. mollicomata. Eastern part of the species' range, in Yunnan and surrounding areas. Shoots more densely hairy, flower stalks thickly felted.

Cultivation

Magnolia campbellii is grown as an ornamental tree for its breathtaking flowers, though successful flowering is limited to mild areas with no late spring frosts. Magnolia campbellii var. mollicomata flowers slightly later and is less likely to have its flowers frost-damaged.
