The Magnolia champaca (L.) Baill. ex Pierre (1880) is an evergreen, or semi-deciduous in the cooler climates, tree, 9-30 m tall, with dense foliage and cylindrical erect trunk, of 50-80 cm of diameter, with grey-brown smooth bark; the young branches and the buds are covered by yellowish tomentum. The leaves, on a 2-4 cm long petiole, are simple, alternate, ovate-elliptic with long pointed apex and entire margin, 10-25 cm long and 4-10 cm broad, of intense glossy green colour above, slightly pubescent below, coriaceous. Deciduous stipules (leafy appendages at the base of the leaf having the main aim to protect it during the initial growth phase) covered by a thick rust coloured tomentum.The flowers, on a 0,4 cm long pedicel, are hermaphroditic, solitary, axillar, of about 6 cm of diameter, with 10-18 petaloid oblanceolate tepals, 2-4 cm long and 0,3-1,2 cm broad, of pale yellow to orange colour, numerous stamina, about 0,6 cm long, and gynoecium formed by several free carpels spirally arranged on a conical receptacle; the flower emit an intense scent perceptible at a distance.
Conical 5-15 cm long infructescence with obovoid fruits (follicles), 1-1,5 cm long, of brown colour, warty, containing 1-4 angular seeds, covered by fleshy pink aril, oily, having a short lasting germinability.
It reproduces by seed, previously cleaned from the aril, that contains a powerful inhibitor, scarified and immersed in warm water for one day, in organic draining soil for acidophiles maintained humid at the temperature of 26-28 °C, with germination times varying from 2 weeks to 3 months, and first blooming starting at the age of 6-7 years. The varieties are propagated by grafting.
Species of great ornamental value and of potential economic importance that since remote times has had an important role in the life and in the civil and religious ceremonies of the local populations. The tree is widely present in the parks and in the gardens, especially in India, and is not absent close to the temples; its flowers, produced almost continuously, are used as ornament and for perfuming the ambients, but especially have an important place in the Hindu and Buddhist traditions.
Cultivable in the tropical and humid subtropical regions and marginally in the temperate warm ones, where temperatures less than 5 °C are exceptional events and of very short duration; requires an exposition in full sun or a partial shade and draining soils, preferably sandy, fertile, deep, humid, but without stagnations, acidic or neutral.
The essential oils extracted from the flowers are utilized in the cosmetics and perfume industry and stand among the most expensive perfumes ingredients, of which the most known is the “Joy”; from them they extraxt also a dye.
The wood, of good quality, is utilized in carpentry, for furnitures, panels, fixtures and in the plywood industry.
All parts of the plant are variously utilized in the traditional medicine for numerous pathologies.
