Magnolia champaca Seeds | White Champaca
LATIN NAME: Magnolia champaca
COMMON NAME: White Champaca
Plant Profile
Magnoliaceae flowers do not separate sepals from petals. Champaca carries ten to fifteen tepals in three overlapping whorls, cream at first and warming to a deep gold-orange, on a flower five to eight centimetres across that opens alone in a leaf axil rather than in the middle of the shoot. Each bloom is short-lived, scenting strongest in the warm, damp morning air, and then the tepals drop whole and litter the ground under the tree.
Inside the tepals, stamens are arranged in a spiral on an elongated receptacle, packed closely with short filaments and long anther tips, and the female organs sit above them on the same axis. After flowering, that axis lengthens into a cluster of follicles, each splitting open to release a seed wrapped in a bright red fleshy aril. Birds take the seeds as soon as the coat is ripe, and the seed loses viability quickly once the aril dries, which is why fresh material is the only reliable sowing stock.
The tree grows fifteen to thirty metres in the tropics and carries glossy, leathery, narrowly oval leaves ten to twenty centimetres long. Nothing about it is deciduous: it leafs, flowers and fruits across the warm season while keeping a full canopy, and it will not tolerate frost. Give it a warm, sheltered position and it makes a dense, dark evergreen crown; push it into a temperate climate and the leaves scorch in the first cold night.
Traditional practice fed the scent into fat, laying flowers on trays of purified fat so the aroma transferred to the medium, and modern houses run the flowers through a solvent to produce a concrete that is then washed with alcohol to give the absolute. Yields are low from a bulky flower, so champaca absolute is an expensive material and is dosed sparingly. In South Asia the cheaper route, steeping flowers in sesame or coconut oil, has been used for hair oil for centuries.
Science & Biotechnology
Analyses of champaca flower scent consistently report phenylethyl alcohol and linalool as leading components, with methyl anthranilate and sesquiterpenes such as caryophyllene carrying the heavier, tea-like undertone. The tepals release more of the mixture as the temperature rises, so a single tree can scent a courtyard in the morning and fade by evening; the compound is held in oil cells within the flower tissue and escapes as the cells are disturbed by warmth and air movement.
Uses & Benefits
The fresh flowers are packed into sesame or coconut oil and left in the sun, then strained, giving a fragrant hair oil still sold in the region. In Java the flowers are floated in drinking water to perfume it, and the same idea turns up in flavoured waters and syrups elsewhere in Southeast Asia.
As a street and garden tree, champaca gives dense shade, tolerates clipping and holds its leaves year-round, so it is planted along avenues and in parks wherever frost is unknown. The pale timber is light and workable and goes into boards and light joinery in its native countries, and the bark has a long local history in decoctions for fevers.
Growing from Seed
Named trees are worth keeping true, and air layering has always been the grower’s answer. Laboratories multiply champaca and its relatives through nodal and axillary bud culture, rooting the shoots in sterile medium and hardening the plantlets in shaded frames, which is how selected flowering lines can be distributed without waiting for seed.
The flower is the reason most people know the tree. It is offered at shrines every morning across its native range, stitched into garlands and floated in bowls of water, and the tree is planted in temple courtyards and beside houses for that purpose alone. Its habit of flowering through the warm months rather than in a single flush keeps a supply coming.
Watch the follicle cluster as it begins to split and take the seed immediately, because the red aril is the clock. Rub the coat off in water, sow at once in a warm, moist mix of loam, leaf mould and coarse grit, press the seed in about twice its own depth, and keep the pan shaded and humid. A deep pot suits the young plant better than a shallow one, since the root runs down before the top grows.
Grow champaca in rich, moist, free-draining soil that is neutral to slightly acid, in full sun with shelter from cold wind. Water steadily through the warm season and ease off in the cooler months. It can be held in a large container for years if the roots are given room and fed lightly, but the first frost will decide the argument, so the pot should be moved indoors well before the cold arrives. Scale insects and mealybugs are the usual glasshouse problems; prune after flowering to shape without cutting the flowering wood.
Our Take
Champaca is worth growing even in a pot, because a single flower will scent a whole room and no temperate magnolia comes close for that. Keep it warm and humid, and remember that the plant sold under the name champaca seed in older lists is the same tree under its former genus. Growers chasing scent should also look at the ylang-ylang, whose flowers supply a major perfumery oil, and at the hardy evergreen Delavay magnolia for a cooler garden.
