Pink Cedar or Mundani is a fast-growing flowering and timber tree native to parts of the Indian subcontinent and Southeast Asia, its natural range extending from the foothills of the Himalayas, east to forested highland areas in Myanmar (Burma), Thailand and Indonesia.
It may reach heights of up to 50 m (164 ft) under favourable forest conditions with a 2 m (6.6 ft) diameter trunk, usually buttressed at the base, unbranched for half its height and supporting a compact columnar or pyramidal crown. The bark is grey to grey-brown and dotted with raised, wart-like pores known as lenticels.
The leaves are very large and twice-feathered, composed of as many as forty ovate leaflets, each up to 10 cm (4 in) long and arranged in pairs along the branches of the leaf. They are shed in the dry season to conserve water, leaving the tree mostly bare and leafless until the rainy season. The new leaflets, when they emerge, are bright red, giving a colourful display before gradually ageing to green.
Equally showy are the orange to red flowers that come into bloom when the tree is leafless, reaching full bloom by the end of the dry season. They are followed by long, flat and winged seedpods that turn brown when mature, about six weeks after the flowering period has ended.
It produces a medium-weight wood, averaging out at around 630 kilograms per cubic meter (39 lbs per cubic ft), which classes it as a hardwood. However, its low natural resistance to decay and termites limits its use outdoors.
The heartwood is an attractive dark red and well-formed logs are sawn into planks for making light articles such as crates, pallets and boxes, including boxes for beehives. In the past, it was used extensively to make large tea chests, in which tea from India was shipped around the world.
The roundwood is easily split and has long been used to make roof shingles. It is also cut for fence posts and is widely used for firewood and for making charcoal.
Its fast growth rate makes it a suitable tree for crop shading, especially for tropical highland crops such as coffee (Coffea arabica) and tea. It is sometimes cultivated in large gardens and parks in its native range where its feathery foliage and showy flowering display can best be appreciated.
The flowers produce abundant nectar that attracts and nourish nectar-feeding birds and possibly honeybees, but there does not appear to be any reliable information on its value to bee forage or honey production.
Grows naturally and has its best development in humid subtropical and tropical lowland to mid-elevation climates, generally in frost-free areas with annual lows of 13 to 22 °C, annual highs of 23 to 34 °C, annual rainfall of 1300 to 5000 mm and a dry season of 4 months or less.
Trees in low rainfall areas or areas with a pronounced dry season tend to develop short trunks, narrow crowns and have a low survival rate.
New plants are usually started from seed, which can be pre-treated to improve germination by immersing them in hot water that is then left to cool. Once established, it performs best on free-draining clay, loam and sand soils of a slightly acid to slightly alkaline nature, generally with a pH of 6.0 to 7.5 and on sites with full to partial sun exposure.
The winged seedpods are designed for dispersal by wind, which can carry them afar and because the seed germinate readily, may cause it to be potentially invasive. It is listed as a weed in at least one reference publication, but there does not appear to be any records of it being a serious weed anywhere, despite being long introduced into areas outside of its native range.
