The morphological characteristics of the West House Begonia deciduous tree - flowers West House Begonia - fruit (Malus), up to 8 meters high; branchlets cylindrical, erect, reddish-brown when young, pubescent old when dark brown, glabrous. Blade elliptic to oblong, 5-8 cm long, 2-3 cm wide, apex acuminate or obtuse, base broadly cuneate or nearly rounded edges closely serrulate, sometimes entire margin, childhood both surfaces pubescent soon shedding hairless; petiole 1.5-3 cm long, pubescent; stipules membranous, lanceolate, entire. Inflorescence nearly umbrella, with flowers 5-8; fine pedicels, 2-3 cm long, sparsely pubescent; spend 4-5 cm in diameter; calyx tube glabrous outside or dense pubescence; calyx lobes triangular-ovate , 3 - mm long, shorter than the calyx tube or nearly as long, apex acute, margin entire outside hairless or nearly hairless, the inner surface of the white fluff; petals ovate, base with short claws, 2-2.3 cm long white open early pink to red; the stamen 20-25 gold (30), long petals half; style, five, four dilute, slightly longer than the stamens, base with white fluff.

Edit this paragraph growth environment hi light, cold, avoid waterlogging, avoid air is too wet, and more resistant to drought, soil and water do not ask, optimum born in the fertile, loose and well-drained sandy loam. Flowering from April to May, the fruit of September. Edit this paragraph distribution originating in China now, Liaoning, Hebei, Shanxi, Shandong, Shaanxi, Gansu, Yunnan cultivated. Edit this paragraph the breeding methods Begonia usually grafted or ramets breeding, breeding can also use methods such as planting, layering, and root cuttings. With grafting proceeds seedlings, flowering may be early, but also to maintain the original fine features. Seed sowing West House Begonia seedlings grow slower, but often mutate and are thus the rootstock or crossbreeding, still sowing method. Rootstock species common in northern China baccata, West House Begonia, crack "Ringo fruit, etc.; southern Hubei Begonia. Begonia seeds before planting, after 30 days to 100 days of cold stratification. Fully laminated, seed emergence fast, neat, and high germination rate; laminated seeds will not germinate, or rarely germinate. Also be picking fruit in the fall, to the meat a little dry after planting in the sand bed, so the natural ripening seed. Overburden depth of about 1 cm lift to go plastic film, plastic film overlying soil moisture emergence timely applicator layer of loose loam, to strengthen the management of fertilizer seedling stage, when the late autumn can be transplanted.
