Durian

Durio zibethinus

Also calledDurian (Malay/Indonesian) · Thurian (Thai) · Sầu riêng (Vietnamese) · Liúlián (Chinese) · Du-yin (Burmese) · King of Fruits (English epithet)

A towering Southeast Asian rainforest tree famous for spiky fruit with a smell banned on many trains and hotels, yet a custardy flesh revered as the 'king of fruits'. Its flowers open at dusk and are pollinated mainly by fruit bats.

Durio zibethinus is the most common tree species in the genus Durio, commonly known as durian, and has edible fruits by the same name. Wikipedia

§1

What it can do

  1. iPollinated chiefly by nectar bats such as the cave nectar bat (Eonycteris spelaea)
  2. iiOdour comes from dozens of volatile sulphur compounds and esters
  3. iiiTrees grow 25–50 m tall in the wild
  4. ivRipe fruit falls from the tree on its own — it is gathered from the ground

Eatenaril (flesh) · seeds (boiled or roasted) · unripe fruit (cooked)

Flesh and cooked seeds are eaten; raw seeds are not. Traditional belief, with some lab support, warns against combining durian with alcohol, as it may inhibit alcohol breakdown.

In the medicine cabinet

TraditionUse
Malay traditional medicineLeaf and root decoctions given for fever and jaundice
Southeast Asian folk beliefConsidered a 'heating' food, balanced by eating 'cooling' mangosteen

Weight of evidence

Traditional. Long historical use; little or no modern clinical evidence.

Active compounds

ethanethiol and related sulphur volatiles, ethyl 2-methylbutanoate, tryptophan

CautionAvoid with alcohol. High in sugar and calories.

Capsule (loculicidal)

Ripens: Varies; main seasons June–August in Malaysia and Thailand

Oval to round fruit 15–30 cm and 1–3 kg, covered in hard pyramidal thorns, green to brown; splits into five sections with creamy yellow, custard-like arils that smell strongly of onion, cheese and fruit.

Seed

2–4 cm

Glossy, chestnut-brown, oval to kidney-shaped seeds 2–4 cm long, enclosed in the soft aril; 1–7 per section

Dispersal
Orangutans, elephants, tigers, bears and other large mammals

Tropical only (USDA 11–12; damaged below about 10 °C). Survives winters down to about 4 °C.

Light
Full sun when mature; shade for young plants
Water
High, with a short dry spell to trigger flowering
Soil
Deep, well-drained, rich loam, pH 5–6.5
Propagation
Grafting (cleft, approach) of named cultivars such as 'Musang King' or 'Monthong' onto seedling rootstock
To harvest
4–6 years from graft; 8–15 years from seed
Climates
Humid equatorial tropical
  1. 1Buy a grafted tree of a named clone; plant 8–10 m apart in deep soil with excellent drainage, as durian is prone to Phytophthora root rot.
  2. 2Shade young trees for the first 1–2 years and keep the soil mulched and moist.
  3. 3Feed regularly with compost and balanced fertiliser; plant other durian clones nearby for better cross-pollination.
  4. 4Prune to a single leader with well-spaced lateral branches for fruit to hang on.
  5. 5Collect fruit as it falls (or tie fruit to branches with nets), and eat within 2–3 days.

Marginalia

Naturalist Alfred Russel Wallace wrote in 1856 that eating durian was 'a new sensation worth a voyage to the East'. Singapore's Esplanade concert hall is nicknamed 'the Durian' for its spiky roof.

Curiosity

Durian is banned on Singapore's metro trains, where signs show it alongside smoking and flammable goods.
