MELBOURNE STREET TREES 152 - STAR MAGNOLIA

Magnolia stellata, sometimes called the star magnolia, is a slow-growing shrub or small tree in the Magnoliaceae family, 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.

This tree grows 1.5 to 2.5 m in height, spreading to 4.6m in width at maturity. Young trees display upright oval growth, but the plants spread and mound with age. The tree blooms at a young age, with the slightly fragrant 7-10 cm flowers covering the bare plant in late winter or early spring before the leaves appear. There is natural variation within the flower colour, 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 tepals. The leaves open bronze-green, turning to deep green as they mature, and yellow before dropping in autumn. They are oblong and about 10 cm long by about an 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. Spring frosts can damage the flowers. The shrub prefers deep, acidic soil. It may be propagated by seed, or more easily by rooting cuttings taken after the flower buds have formed.

  1. Look at those fuzzy buds, love the elongated star shaped flowers. Don't know how well slightly frangrant travels but I've got fond memories of the scent of magnolia bushes in the summer wind.
