This genus contains several fine flowering trees or shrubs, mostly deciduous, but evergreen in such as glauca and grandiflora, the latter being well known for its large shining-green Laurel-like leaves and huge white flowers in summer. The deciduous kinds most largely grown for sale include acuminata, the North American "Cucumber Tree", 30-80 ft. high, with oblong pointed leaves, 6-12 in. long, and yellowish-green flowers; Campbelli, North India, with oval lance-shaped leaves and pale-rose and crimson flowers; conspicua (Yulan), one of the best-known Chinese kinds with obovate leaves and large erect fragrant white flowers produced on bare branches from February to April and later. There are several varieties, such as Soulangeana (fig. 429), white and purple; Lennei, rich purple; Alexandrina; and others. M. Fraseri (auriculata), large leaves, 1 ft. long, lobed at base, and white flowers; hypoleuca, large creamy-white flowers; macro-phylla, leaves 1-3 ft. long, flowers white with purple blotch at base of petals; obo-vata, 5-6 ft., flowers white within, purple outside; parvi-flora, flowers globular, white tinted rose; salicifolia, 15-20 ft., with Willow-like leaves and white six-petalled flowers; stellata (Halleana), 5 ft., with white starry flowers in February and March; Umbrella (tripetala), white; and Wat-soni, creamy white. Magnolias are usually increased by layering, but also from seeds, cuttings, and by grafting on stocks of acuminata or Umbrella. Some kinds are rather tender.
