Origin
Where Does Star Anise Come From?
Almost all of it grows in two neighbouring regions: Guangxi in China and the northern border provinces of Vietnam. Here is where, when it is picked, how it is dried and graded, and why the production figures disagree.
Quick answer
Southern China and northeast Vietnam. Star anise is the dried fruit of Illicium verum, an evergreen tree native to Guangxi and northern Vietnam. China grows about 80% of the world’s crop, over 90% of that in Guangxi (2018); Vietnam is the second-largest producer, and most of its crop comes from Lạng Sơn (Lang Son). The fruit is picked green in a main autumn harvest and a smaller spring one, then dried to brown.
Star anise comes from the dried, star-shaped fruit of Illicium verum, an evergreen tree native to southern China — mainly Guangxi — and northeast Vietnam.1 China grows about 80% of the world’s supply and Vietnam is the second-largest producer,2 with most Vietnamese star anise coming from the border province of Lạng Sơn (Lang Son).3 The sections below go further than that one line: provinces and former districts, the two harvests, drying, grading, the geographical indication, and sourced export figures.
Star anise grows in two neighbouring regions
Most commercial star anise comes from two producing areas that meet at the China–Vietnam border. Every figure below carries its year and source, because the sources do not agree (see why the numbers disagree).
| Country | Main growing areas | Share or output (year, source) | Notes |
|---|---|---|---|
| China | Guangxi, in the south | About 80% of world output; Guangxi grew over 90% of China’s crop in 20182 · 90,000–95,000 t a year, per Vietnamese trade press (2026)4 | The press figure gives no source of its own |
| Vietnam | Lạng Sơn, Cao Bằng, Quảng Ninh and former Bắc Kạn3 | About 22,000 t a year (2026)4; other estimates from about 16,000 t a year (2024)5 | Second-largest producer2 |
Three of Vietnam’s four star anise provinces — Lạng Sơn, Cao Bằng and Quảng Ninh — lie on the border with Guangxi. In practice the two producing regions are one belt of hill country divided by a frontier, which is why the same species is grown on both sides.
Where is star anise native to?
Kew’s Plants of the World Online gives the native range as “China (S. & W. Guangxi) to N. Vietnam”.1 Older accounts draw it more widely: PROSEA (1999) places its origin in south-eastern China (Guangxi, Guangdong, Fujian, Guizhou and Yunnan) and northern Indo-China (Laos, Vietnam), and notes that the tree is known only in cultivation.6 The ICRAF tree database lists China and Vietnam as native and Jamaica, Laos and the Philippines as places it has been introduced.7
Where star anise grows in Vietnam
Where is star anise grown in Vietnam? A 2021 study names four provinces — Lạng Sơn, Cao Bằng, Bắc Kạn and Quảng Ninh — with a combined area of about 50,000 ha.3 Lạng Sơn is by far the largest.
Lạng Sơn. Its star anise area is reported at about 30,000–43,000 ha depending on source and year: 30,647 ha in 2020,3 more than 35,000 ha in 2022,8 33,738 ha9 and more than 43,370 ha10 in two 2023 reports, and 40,000 ha in 2026.4
Within the province, production is concentrated in a few former districts. The breakdown below is from the Lạng Sơn Statistics Office, as published in the 2021 study.3 Văn Quan alone is reported to have about 15,000 ha, roughly half the province’s star anise.11
| Former district | Share of Lạng Sơn star anise production |
|---|---|
| Văn Quan | 32% |
| Bình Gia | 25% |
| Cao Lộc | 11% |
| Tràng Định | 8% |
| Văn Lãng | 8% |
| Other | 16% |
Quảng Ninh and Cao Bằng. Quảng Ninh is reported at about 8,600 ha and Cao Bằng at about 4,500 ha (2026).4
Bắc Kạn. Star anise is grown there,3 but none of the sources we could verify publishes its area, so we give none.
The tree behind the spice
Illicium verum is an evergreen tree of the family Schisandraceae.6,14 It grows 8–15 m tall, occasionally 20 m, with a trunk up to 30 cm across.7 The fruit is a star of 6–8 boat-shaped follicles, rarely up to 12–13, each holding one seed.7

How does star anise grow as a crop? It is a long-lived plantation tree. It starts flowering at 5–6 years, bears seed from 9–10 years and can continue for about 80 years.7 In Lạng Sơn, trees are harvested from 7–10 years after planting, sometimes for as long as 100 years.3
Yields vary with age. ICRAF gives 8–12 kg of fresh fruit per mature tree per season;7 PROSEA gives 5–10 kg for trees aged 13–25 years and 10–20 kg for older trees.6
Commercial star anise cultivation needs acid soil. ICRAF describes feralitic soils of pH 4–6, not limestone, with 1,500–2,400 mm of rain a year, at elevations up to about 2,000 m.7
From the tree onwards, the chain looks like this.

Two harvests a year: the autumn crop and the spring crop
The tree flowers and fruits twice a year,7 so the trade has two crops. Each row below is one source’s statement; they disagree by about a month.

The main (autumn) crop runs roughly August–October; the smaller spring crop roughly January/February–April. The months shift by locality and year, and the sources disagree by about a month.11,18,8 Exporters describe the autumn crop as giving more fruit, with larger, better-coloured stars than the spring crop; that is a seller’s description, not a measurement.18
Output also swings from year to year. Lạng Sơn produced 13,521 t in 2017 but only 8,419 t in 2018, before recovering to 14,390 t in 2019.3
From green fruit to brown star: how star anise is dried

Star anise is picked green, just before it ripens and before the follicles split open.7,21 Drying turns the green fruit brown. A 2014 forestry study describes three traditional methods used in Lạng Sơn and Quảng Ninh:15
- Blanching. The fruit is dipped in boiling water before drying. It gives an attractive red-brown colour but takes a lot of labour, and has almost disappeared.
- Sun-and-cover. The fruit is spread on a yard or tarpaulin in the morning sun; after 5–6 hours it is covered with white plastic sheeting, and 4–5 hours later it has turned yellow-brown. It depends on the weather.
- Sack kiln. Sacks of fruit are stacked on a wooden rack over a charcoal or wood fire and covered with a tarpaulin, at 30–40 °C for 12–18 hours. It needs less labour and handles 1–3 t of fresh fruit per batch, so it is the common method; the drawbacks are uneven colour and a risk of smoke taint.

Some growers have invested in steam dryers. One Lạng Sơn grower quoted in the national press said a steam dryer raised her capacity more than tenfold compared with manual drying — one family’s account, not a measured average.10
Drying removes most of the weight. PROSEA gives 25–30 kg of dried fruit from 100 kg fresh, after about ten days of sun drying;6 ICRAF gives about 1 kg dried from 4–5 kg fresh.7 That ratio of roughly four to one matters when reading production figures.
The dried fruit contains 5–8% essential oil, of which anethole makes up 85–90%; about 10 kg of dried fruit yields 1 kg of oil.7 Other sources report trans-anethole at 70–93%6 and above 80%2 of the oil.
How star anise is graded and traded
Two published standards cover the dried fruit. ISO 11178:1995, Star anise (Illicium verum Hook. f.) — Specification, sets requirements for the dried fruit and was reviewed and confirmed in 2024.16 TCVN 8852:2011, Vietnam’s national standard Hoa đại hồi, applies to whole and broken dried star anise.17 Their numeric limits are in paid texts we have not read, so this page does not quote them.
Export offers use their own vocabulary, not defined by a single standard. Sellers distinguish the autumn crop from the spring crop and whole stars from broken ones.18
One Vietnamese exporter’s listing, for example, states: moisture at most 13.5%, admixture at most 1%, broken stars at most 8%, ash at most 9%, and stars at least 2 cm across.18 That is a single seller’s specification, shown to illustrate what an offer looks like — not a standard and not a recommendation.
Lạng Sơn star anise: a protected geographical indication
Lạng Sơn star anise has been a protected geographical indication in Vietnam since 2007.8 The protected name covers both the fruit and its essential oil: “Quả hồi và tinh dầu hồi Lạng Sơn”.10
Geographical indicationGI
A protected name that ties a product to a delimited place of production. For a buyer, “Lạng Sơn” on a protected product means it comes from the defined Lạng Sơn growing area, not simply from Vietnam.
In 2014 the European Commission published a list of Vietnamese geographical indications for consultation during free-trade negotiations; it includes “Lạng Sơn — Star aniseed”.22 According to Vietnamese government and press sources, Lạng Sơn star anise has been protected in the EU since 2020 under the EU–Vietnam Free Trade Agreement, as one of 39 Vietnamese geographical indications.9,10 We have not found the certificate number and do not print one.
How much star anise does Vietnam produce? Why the numbers disagree
There is no single answer. Each row below is one source’s figure, with the year it refers to.
| Indicator | Value | Year | Source |
|---|---|---|---|
| Vietnam, area | About 50,000 ha (four provinces) | 2021 or earlier | Sáng & Nguyệt3 |
| Vietnam, area | About 40,000 ha | 2024 | Vietnam Pepper Association5 |
| Vietnam, area | About 55,000 ha | 2026 | DTiNews4 |
| Vietnam, output | More than 2,000 t a year | Before 1999 (historical) | PROSEA6 |
| Vietnam, output | More than 16,000 t a year | 2024 | Vietnam Pepper Association5 |
| Vietnam, output | About 22,000 t a year | 2026 | DTiNews4 |
| Lạng Sơn, planted area | 30,647 ha | 2020 | Sáng & Nguyệt3 |
| Lạng Sơn, area | 33,738 ha · more than 43,370 ha | 2023 | MOIT9 · Nhân Dân10 |
| Lạng Sơn, share | About 70% of national area | 2023 | Nhân Dân10 |
| Lạng Sơn, share | About 87.5% of national output | 2026 | DTiNews4 |
| Lạng Sơn, output | 13,521 · 8,419 · 14,390 · 14,503 t (fresh or dried not stated) | 2017–2020 | Sáng & Nguyệt3 |
| Lạng Sơn, dried output | 7,500–16,000 t a year | 2023 | Nhân Dân10 |
| Lạng Sơn, dried output | 12,000–14,000 t a year | 2026 | CMB News20 |
| China, output | 90,000–95,000 t a year | 2026 | DTiNews4 |
Three things probably explain most of the spread. These are our explanations, not findings of the sources.
- Planted area is not harvested area. In 2020 Lạng Sơn had 30,647 ha planted but 24,886 ha harvested;3 young trees take 7–10 years to bear.
- Fresh and dried tonnes get mixed. Fresh fruit dries down roughly four to one.6,7 A figure of 18,000–20,000 t a year quoted for Văn Quan alone11 only makes sense as fresh fruit, since the same article gives yields of 2–2.5 t of fresh fruit per hectare.
- Harvests swing. Lạng Sơn’s output fell from 13,521 t to 8,419 t between 2017 and 2018.3
Treat any single figure as an estimate for a given year.
Who buys Vietnamese star anise
Export figures come from a single trade body, which makes them easier to compare across years than production estimates. The Vietnam Pepper and Spice Association (VPSA), which also reports Vietnam’s cinnamon exports,23 gives these numbers for star anise.
| Period | Volume | Value | Main markets |
|---|---|---|---|
| 2025 (full year) | 14,307 t (+2.2% on 2024) | US$58.7 million (−8%) | India 9,896 t (about 70%); United States 1,030 t (+82.9%)24 |
| January–May 2026 | 5,769 t (−24.9%) | US$22.8 million (−21.1%); average US$3,951/t | Asia 78.1%, including India 3,599 t (−39%); the Americas 816 t (+5.7%); Europe 413 t (+56%)4 |
Dividing the 2025 value by the volume gives an average of about US$4,100 a tonne (our calculation, not a reported price). This page does not track current prices.
A 2021 study of Lạng Sơn star anise names China and Europe as its two largest export markets.3 The two sources measure different things — one province in an earlier period against national exports in 2025 — so they do not cancel each other out.
Not to be confused with
Star anise is not related to anise seed (Pimpinella anisum), a small herb in the carrot family; the two simply share the aroma compound anethole.25,26 See star anise vs anise seed.
Not to be confused with Japanese star anise (Illicium anisatum), a different and toxic species that is not sold as a spice.21 See Japanese star anise vs Chinese star anise.
Star anise outside the kitchen: shikimic acid
Star anise is a major natural source of shikimic acid, an organic compound.21,2 Shikimic acid is the starting material for the industrial synthesis of oseltamivir, the antiviral sold as Tamiflu.21,2 A 2006 report in Environmental Health Perspectives described Roche, the drug’s maker, moving much of its supply from extraction out of star anise to fermentation with E. coli bacteria.19 This is a supply-chain fact, not a health claim.

Frequently asked questions
What country produces the best star anise?
No official ranking exists, and no source we found measures one origin against another. China grows about 80% of the world’s star anise and Vietnam is second. Buyers judge each lot on stated specifications such as moisture, extraneous matter and broken share, and on standards such as ISO 11178 and Vietnam’s TCVN 8852:2011. Lạng Sơn star anise has been a protected geographical indication in Vietnam since 2007, and exporters describe autumn-crop stars as larger than spring-crop ones.
What spices is Vietnam known for?
Black pepper, cinnamon and star anise: the Vietnam Pepper and Spice Association, named for pepper, also reports Vietnam’s cinnamon and star anise exports. Star anise comes from the northern border provinces, led by Lạng Sơn, and Vietnam exported 14,307 tonnes of it in 2025. For the bark spice, see Vietnamese cinnamon.
