Nursery Stock 0 views
Yulan magnolia, also known as white Yulan magnolia, is a deciduous tree of the Magnolia genus, with an oval or flattened-spherical crown and grayish-brown bark. Its single leaves are alternate, obovate-rounded, with a abruptly pointed tip. The flowers are terminal, with flower buds formed in the previous autumn, blooming before the leaves. The flowers are white, fragrant, 10-16 cm in diameter, upright bell-shaped, with 9 tepals, obovate, white, arranged in whorls of three, and numerous stamens and pistils. Its main variety is the purple-flowered Yulan magnolia (var. FurFurascens), whose tepals are purplish-red outside and clear white inside. Both magnolias are highly favored by people. Yu

Yulan magnolia, also known as white Yulan magnolia, is a deciduous tree of the Magnolia genus, with an oval or flattened-spherical crown and grayish-brown bark. Its single leaves are alternate, obovate-rounded, with a abruptly pointed tip. The flowers are terminal, with flower buds formed in the previous autumn, blooming before the leaves. The flowers are white, fragrant, 10-16 cm in diameter, upright bell-shaped, with 9 tepals, obovate, white, arranged in whorls of three, and numerous stamens and pistils. Its main variety is the purple-flowered Yulan magnolia (var. FurFurascens), whose tepals are purplish-red outside and clear white inside. Both magnolias are highly favored by people.

The Yulan magnolia flower is white as jade, and its fragrance resembles that of an orchid, hence its name. The Ming dynasty poet Zhang Maowu wrote a fine line praising the Yulan magnolia: "If but one branch can compare to jade, why need nine plots to seek the orchid." He ingeniously embedded the two characters "yu" (jade) and "lan" (orchid) into the poem. In ancient times, people liked to plant Yulan magnolia, crabapple, and peony together in the same garden, implying the meaning of "jade hall wealth and honor."

The Yulan magnolia is native to the mountainous areas of central China. It prefers sunny, warm, humid, and well-drained sites, and requires fertile soil rich in organic matter. Its roots are fleshy and afraid of waterlogging. It has strong cold resistance, can overwinter safely at -20°C, and can also grow in semi-shady environments.

In the past, it was mostly propagated by grafting onto Magnolia as rootstock, or by air layering. In recent years, after the promotion of the application of growth hormones, treating cuttings with hormones has been successful. In June to July, select young shoots of the current year, dip the cuttings in 500 mg/L α-naphthaleneacetic acid, and then insert them under plastic film cover; the survival rate can reach about 70%. In addition, seed propagation is also widely used. For sowing, note that the seeds should be treated immediately after collection: first rub off the red aril with wood ash slurry, store them in sand promptly, and sow in spring the following year, or sow immediately in autumn after treatment. After the seedlings emerge, appropriate shading should be provided during the midsummer of the first and second years, and they must not be exposed to strong sunlight; in cold winter regions, appropriate protection for overwintering should also be provided.
