Durian

Lore & Background

The name durian is derived from the Malay word duri 'thorn', combined with the noun-building suffix -an. The Oxford English Dictionary first cites the word from a 1588 translation of Juan González de Mendoza's Historie of the Great and Mightie Kingdome of China. The name of the type species, Durio zibethinus, is derived from the Italian zibetto 'civet', as the strong pungent odour of the fruit reminded people of the smell of the animal.

Durian trees are large, growing to 25–50 metres in height depending on the species. The leaves are evergreen, elliptic to oblong and 10–18 centimetres long. The flowers are produced in three to thirty clusters together on large branches and directly on the trunk. Durian trees have one or two flowering and fruiting periods per year. A typical durian tree can bear fruit after four or five years. The fruit can grow up to 30 cm long and 15 cm in diameter, and typically weighs 1 to 3 kilograms.

The earliest known European reference to the durian is the record of Niccolò de' Conti, who travelled to Southeast Asia in the 15th century. The Portuguese physician Garcia de Orta described durians in Colóquios dos simples e drogas da India published in 1563. In 1741, Herbarium Amboinense by the German botanist Georg Eberhard Rumphius was published, providing the most detailed and accurate account of durians for over a century.

Reader's Guide

The durian holds a significant place in Southeast Asian culture and commerce. It is the only species of the genus Durio available on the international market, with over 300 named varieties in Thailand and over 200 in Malaysia as of 2021. The fruit's strong odour, which some find pleasantly sweet and others overpowering, has led to bans in some hotels and public transportation services in Southeast Asia, such as in Singapore and Bangkok. The flesh can be consumed at various stages of ripeness and is used to flavour a wide variety of sweet desserts and savoury dishes in Southeast Asian cuisines. The seeds can be eaten when cooked. Since the early 1990s, domestic and international demand for durian in the ASEAN region has increased significantly, and in the early 2020s, a durian craze in China led to a large increase in international trade of the fruit. The durian has been cultivated for centuries at the village level, probably since the late 18th century, and commercially since the mid-20th century.

Did You Know?

• The name durian is derived from the Malay word duri 'thorn', referring to the prickly thorns on the fruit's rind.
• Durio zibethinus is the only species available on the international market.
• The fruit can grow as large as 30 cm long and 15 cm in diameter, and typically weighs 1 to 3 kg.
• Some hotels and public transportation services in Singapore and Bangkok have banned the fruit due to its persistent strong odour.

Physical Form & Sensory Profile

The durian is immediately striking in its physical presence. The fruit can reach 30 cm in length and 15 cm in diameter, typically weighing between one and three kilograms. Its shape is not uniform — it can be oblong or round — while the husk shifts across a spectrum from green to brown, and the flesh inside ranges from pale yellow to red depending on the species. The rind is densely covered in prickly thorns, a feature so defining that it gave the fruit its name from the Malay word duri, meaning thorn. Inside, the flesh offers a creamy, pudding-like texture with a complex flavour that carries savoury undertones alongside sweetness. The most polarising aspect, however, is the odour. Some people find the fragrance pleasantly sweet, while many others describe it as overpowering and unpleasant. The smell is so persistent that it can linger for several days, a quality that has prompted hotels and public transit systems in cities like Singapore and Bangkok to prohibit the fruit entirely. The type species name, zibethinus, itself references the Indian civet, as the pungent aroma reminded early observers of that animal's scent.

Botany, Pollination & Species Diversity

Durian trees are substantial, reaching heights of 25 to 50 metres depending on the species. Their evergreen leaves are elliptic to oblong, measuring 10 to 18 centimetres in length. Flowers appear in clusters of three to thirty directly on large branches or the trunk, each bearing a calyx and typically five petals. These flowers are notably large and feathery, producing copious nectar and releasing a heavy, sour, buttery odour — traits characteristic of flowers adapted to vertebrate pollinators. In fact, several bat species, including the cave nectar bat, the lesser short-nosed fruit bat, and the large flying fox, serve as pollinators. Two other species rely on spiderhunter birds, while one is pollinated by giant honey bees and birds in addition to bats. Scientists have hypothesised that the evolution of larger flowers and monothecate anthers in the Durio clade coincided with a shift from beetle pollination to vertebrate pollination. A typical tree begins bearing fruit after four or five years, with the fruit maturing roughly three months after pollination. The genus encompasses 30 recognised species, at least nine of which yield edible fruit, though only Durio zibethinus is commercially cultivated on a large scale and traded internationally.

Origins, Early Encounters & Taxonomic History

The durian's roots are believed to lie in Borneo and Sumatra, with wild trees across the Malay Peninsula and cultivated orchards stretching from India to New Guinea. Four centuries ago, the fruit was already being traded across what is now Myanmar and actively grown in Thailand and South Vietnam. The earliest known European account comes from Niccolò de' Conti, a 15th-century traveller to Southeast Asia, who described a green fruit the size of a watermelon containing five elongated segments resembling thick butter. The Portuguese physician Garcia de Orta followed with a description in 1563, and the German botanist Georg Eberhard Rumphius published the most detailed and accurate account in his 1741 Herbarium Amboinense, a work that stood as the definitive reference for over a century. The genus Durio, established by Rumphius, has since undergone considerable taxonomic revision, with species added and removed over time. Early confusion arose between the durian and the soursop, both bearing thorny green fruit; the Malay name for soursop, durian Belanda, literally means Dutch durian. In the 18th century, Johann Anton Weinmann even classified the durian with Castaneae, drawing a parallel to the horse chestnut.

Culinary Role & Cultural Presence

In Southeast Asian kitchens, the durian transcends its role as a simple fruit. Its flesh, enjoyable at various stages of ripeness, flavours a wide array of sweet desserts and savoury dishes across the region. The seeds, when cooked, are also edible, adding another dimension to its culinary versatility. In Thailand alone, more than 300 named varieties exist, and Malaysia counts over 200 as of 2021, reflecting the depth of local cultivation and appreciation. The fruit's reputation as the king of fruits in several regions captures its cultural prominence. Yet this status carries practical consequences. The odour, which can persist for days, has led to outright bans in certain public spaces. Hotels and public transportation services in cities such as Singapore and Bangkok have prohibited the durian, recognising that its aromatic intensity can overwhelm enclosed environments. Despite these restrictions, the fruit remains a cornerstone of regional food culture, its complex, savoury-sweet flavour and creamy texture making it indispensable to both everyday cooking and celebratory dishes. The Portuguese introduced Durio zibethinus to Ceylon in the 16th century, and seedlings were later sent to botanical gardens in the Americas, though cultivation there has remained confined to those institutional settings.
