Origin guide
Star Anise
The dried fruit of an evergreen tree from the hills on either side of the China–Vietnam border. This guide follows it from the tree to the export market.

In short
Star anise is the dried, star-shaped fruit of Illicium verum, an evergreen tree native to southern China and northern Vietnam. China grows most of the world’s crop; Vietnam is the second-largest producer, and its star anise comes mainly from the border province of Lạng Sơn (Lang Son).

Star anise is grown commercially in two neighbouring regions: Guangxi in southern China and the northern border provinces of Vietnam. Start with where star anise comes from — the growing regions, the two harvests, drying, grading and trade, with every figure dated and sourced. The guides below cover how it differs from other spices and look-alikes.

From tree to trade
Six steps take star anise from the tree to the export market. Each step links to the sources behind it.
- 01Place
Border provinces
Lạng Sơn, Cao Bằng, Quảng Ninh and Bắc Kạn, across the border from Guangxi.2
- 02Plant
An evergreen tree
Illicium verum grows 8–15 m tall and bears commercial fruit from roughly 7–10 years, for decades after.5,2
- 03Harvest
Picked green, twice a year
Fruit is picked green, before it splits, in a main autumn crop and a smaller spring crop.5,7
- 04Process
Dried to brown
Sun-and-cover drying or a sack kiln at 30–40 °C for 12–18 hours; 100 kg of fresh fruit gives 25–30 kg dried.10,3
- 05Grade
Whole stars and broken
ISO 11178 and Vietnam’s TCVN 8852 specify the product; offers distinguish autumn from spring crop and whole from broken.11,12,13
- 06Use & world
Spice and industry
The essential oil is mostly trans-anethole; the fruit is also a natural source of shikimic acid.4,14

Guides
- Where star anise comes from — Guangxi and Lạng Sơn, provinces and former districts, the autumn and spring crops, drying, ISO and TCVN grading, the Lạng Sơn geographical indication, and why production figures disagree.
- Star anise vs anise seed — two unrelated plants that share an aroma compound, compared species to species.
- Japanese vs Chinese star anise — how the toxic look-alike Illicium anisatum differs from the spice, why the dried fruits cannot be told apart by eye, which laboratory methods can, and what to ask a supplier.

Where it grows
In Vietnam, star anise grows in Lạng Sơn, Cao Bằng, Quảng Ninh and former Bắc Kạn, now part of Thái Nguyên.2,15 Lạng Sơn is the centre of the crop: see the Lạng Sơn region page for the province on the map and its sourced facts.
