Kiwi: The Chinese Gooseberry Renamed for Marketing

The kiwifruit (Actinidia deliciosa) is one of horticulture's most successful 20th-century commercial introductions. Native to southern China and known there for centuries as "yang tao" or "Chinese gooseberry," the fruit was renamed "kiwifruit" by New Zealand growers in 1959 to avoid Cold-War-era tariffs and to associate the export product with their national bird.

Origin and native range

The kiwi is native to the mountainous valleys of southwestern China — modern Sichuan, Yunnan, and Hubei provinces. Wild Actinidia species still grow there. The fruit was a regional Chinese specialty for centuries but never spread internationally until New Zealand cultivation began in the early 1900s.

History and the New Zealand boom

A New Zealand schoolteacher, Isabel Fraser, brought kiwi seeds back from a visit to China in 1904. Wanganui nurseryman Alexander Allison planted them, and in 1910 produced the first New Zealand kiwifruit. Commercial production began in the 1930s; the variety Hayward was selected in 1924 and became the global standard. The renaming from "Chinese gooseberry" to "kiwifruit" in 1959 was a marketing masterstroke — within 30 years New Zealand had built a billion-dollar export industry. Italy is now the world's largest producer, followed by China and New Zealand.

Where kiwis grow today

Italy, China, New Zealand, Iran, Greece, and Chile are the largest producers. Hardy kiwi varieties (Actinidia arguta, Actinidia kolomikta) can grow in much colder climates than the standard Hayward — extending kiwi cultivation north into Canada, the northern U.S., and Russia.

How to grow kiwis

1. Climate: Standard kiwi (Hayward) USDA Zones 7-9. Hardy kiwi (Actinidia arguta) Zones 4-8.
2. Soil: Well-drained loam, pH 5.5-7.0.
3. Sun: Full sun, 6-8 hours.
4. Pollination: Kiwis are dioecious — separate male and female plants. Plant one male for every 6-8 females.
5. Trellis: Strong trellis or pergola — vines are vigorous and heavy.
6. Spacing: 4-5m between vines.
7. Watering: Consistent. Kiwis are thirsty plants.
8. Fertilizing: Annual compost; light nitrogen in spring.
9. Pruning: Heavy annual winter pruning. Kiwis fruit on year-old wood. Major training system: T-bar trellis with horizontal cordons.
10. First fruit: 3-5 years.

Varieties

• Hayward (standard) — the global supermarket standard; brown fuzzy skin, bright green flesh.
• SunGold / Gold3 — newer New Zealand cultivar, yellow flesh, sweeter, less hairy.
• Issai (hardy kiwi) — self-fertile; small grape-sized fruit with smooth edible skin.
• Anna (hardy kiwi) — productive; needs separate male pollinator.
• Kolomikta (Russian arctic kiwi) — extremely hardy, edible variegated leaves.

Nutrition

About 61 calories per 100g. Kiwis contain more vitamin C than oranges by weight (over 90mg per 100g vs orange's 53mg). They are also high in vitamin K, vitamin E, folate, fiber, and contain actinidin, a protein-digesting enzyme similar to bromelain in pineapples.

Bottom line

A 20th-century marketing success built on solid horticulture. If you have a sturdy pergola and a warm-temperate climate, plant a Hayward female and a male pollinator and you have decades of fruit.
