''Magnolia stellata'', sometimes called the star magnolia, is a slow-growing shrub or small tree native to Japan. It bears large, showy white or pink flowers in early spring, before its leaves open. This species is closely related to the Kobushi magnolia (''Magnolia kobus''), and is treated by many botanists as a variety or even a cultivar of that. However, ''Magnolia stellata'' was accepted as a distinct species in the 1998 monograph by Hunt.〔Hunt, D. (ed). 1998. ''Magnolias and their allies''. International Dendrology Society & Magnolia Society. ISBN 0-9517234-8-0〕 == Description == This tree grows 1.5 to 2.5 m(〔rhs 2013〕 in height, spreading to 4.6m in width at maturity. Young trees display upright oval growth, but the plants spread and mound with age.〔(Magnolia stellata )〕 The tree blooms at a young age, with the slightly fragrant 7–10 cm (3–4 in) flowers covering the bare plant in late winter or early spring before the leaves appear. There is natural variation within the flower color, which varies from white to rich pink; the hue of pink magnolias also changes from year to year, depending on day and night air temperatures prior to and during flowering. The flowers are star-shaped, with at least 12 thin, delicate petal-like tepals—some cultivars have more than 30. The leaves open bronze-green, turning to deep green as they mature, and yellow before dropping in autumn. They are oblong and about 4 in (10 cm) long by about an 1.5 in (4 cm) wide. These magnolias produce a reddish-green, knobby aggregate fruit about 2 in long that matures and opens in early autumn. Mature fruit opens by slits to reveal orange-red seeds, but the fruits often drop before developing fully. Young twigs have smooth, shiny chestnut brown bark, while the main trunks have smooth, silvery gray bark. Like the saucer magnolia (''Magnolia'' × ''soulangeana),'' it is deciduous, revealing a twiggy, naked frame in winter. Plants have thick, fleshy roots which are found fairly close to the surface and do not tolerate much disturbance. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Magnolia stellata」の詳細全文を読む スポンサード リンク
