Michelia champaca Seeds | Champak

Champak (Michelia champaca) with intensely fragrant golden-orange flowers among glossy green leaves — Champak (*Michelia champaca*): Magnoliaceae, the golden-flowered temple tree whose perfume perfumers chase.

LATIN NAME: Michelia champaca

COMMON NAME: Champak

Plant Profile

Champak is the fragrant tree of South and Southeast Asia, an evergreen magnolia relative that grows twenty to thirty metres in its home forests and carries narrow, glossy leaves beneath a crown that flowers on and off for most of the year. The blooms sit close against the twigs like small golden goblets, orange to yellow, and their scent is extraordinary: heavy, sweet and carrying, noticeable from a good distance on a still evening.

It is a temple tree in the oldest sense. The flowers are strung into garlands for offerings across India and further east, and the tree is woven through religious verse from the Ramayana onward. A mature champak standing in flower is one of the great sensory experiences of tropical horticulture.

Science & Biotechnology

The perfume is chemistry in action: champaca flowers yield an absolute prized in fine fragrance, built around linalool and a suite of esters and sesquiterpenes, and it has been a component of celebrated perfumes for over a century. The species is also the mother of Michelia x alba, the white champaca of Southeast Asian gardens, one of the most planted fragrant trees in the tropical world, which arose from a cross with the mountain michelia and is propagated only by grafting for the same reason double crabapples are.

Botanically the seeds are the demanding part. Like many tropical magnolias, champak seed is recalcitrant: it cannot be dried and stored, and viability begins falling within weeks of harvest, a trait that shapes every commercial propagation plan for the species.

Uses & Benefits

In the landscape it serves as a shade tree, avenue tree and fragrant garden anchor in frost-free climates, and no other flowering tree of the region fills an evening garden so quickly with scent. The flowers are sold by weight in Indian markets for garlands and temple offering, a small but real economy around the tree’s natural generosity.

Folk tradition uses the bark as a febrifuge and the aromatic leaves and flowers in washes and infusions, part of the vast unsystematic pharmacopoeia of the region. Growers outside the tropics value it as a conservatory subject, where a potted champak in flower can scent an entire glasshouse.

Growing from Seed

Seed must be sown fresh, and nothing about the process is forgiving of delay. Gather the follicles as they split, clean the aril off the seeds by hand in water, and sow the same week, half a centimetre deep in a loose, humus-rich compost kept at twenty-five degrees or a little above. Germination comes within two to five weeks if the seed is genuinely fresh, and fails almost completely if it is not.

Seedlings grow fast once moving and want warm, humid, bright conditions with no cold nights. This is strictly a frost-free tree; a hint of chill will check it and a frost will end it. Pot on steadily and give it the sunniest, most sheltered position available.

Our Take

Champak does one thing perfectly and needs two things absolutely: fresh seed and warmth. Get both right and the growth is startling; lose either and the project stalls. For growers in the true tropics it remains the finest fragrant tree available from seed.
