What Is Date-plum? Benefits, Uses, and Taste
Date-plum—scientifically known as Diospyros lotus—is a sweet, aromatic fruit belonging to the persimmon family and has enchanted civilizations for millennia. Revered for its complex flavor and lauded for its medicinal properties, date-plum holds a unique place in the annals of both culinary and natural medicine. This article delivers an in-depth exploration of the origins, nutritional values, traditional and modern uses, and the taste experience of this fascinating fruit.
Date-plum Overview
Date-plum is a small, round fruit, typically measuring 1 to 2 centimeters in diameter—about the size of a large cherry. Although often associated with plums or dates due to its flavor, it is a distinct species of persimmon. The fruit can be found in shades ranging from golden yellow to deep purple-brown and is edible both fresh and dried, with the latter variety resembling the traditional appearance and sweetness of dates.
Origin and History
Date-plum is native to a wide swath of the Old World, stretching from Eastern Asia and the Caucasus through the Mediterranean all the way to Spain, with historical significance in Persia and Greece. The name “date-plum” references its dual resemblance in taste to both dates and plums, and the ancient Greeks dubbed it the fruit of the gods. Some sources even suggest that it was the legendary ‘lotus’ of Homer’s Odyssey, renowned for its sweetness and soporific qualities.

The date-plum tree is a robust deciduous species, growing between 15 and 30 meters tall, with distinctive oval, glossy, leathery leaves that may reach up to 15 centimeters in length. The bark of mature trees is grey and peels with age. The tree is dioecious, meaning individual trees are either male or female, and both sexes are needed for pollination. Its inflorescences—small flowers—blossom in June or July.

- Flowers: Small, inconspicuous, with males in clusters and females singly.
- Fruit: Berry-like, 1–2 cm in diameter, ripening to yellow, orange, or brownish-purple. Fruits soften and sweeten as they ripen.
- Seeds: Enclosed in a tough shell, usually present in pollinated fruit.
- Ripening season: Varies by region; January–February in India, April–May in China.
Cultivation and Harvest
- Climate adaptation: Thrives in subtropical and warm temperate zones.
- Soil: Prefers well-drained, fertile soils.
- Propagation: Typically via seeds or grafting.
- Harvest: Fruits are best picked when fully ripe and soft to the touch, sometimes after the first frost, as it reduces astringency.

- Ripening: If picked while firm, allow to ripen at room temperature until soft. First frosts may sweeten the fruit further by reducing astringency.
- Storage: Ripe fruit should be consumed shortly after picking; dried fruits can be stored in a cool, dry place for months.
