Kiwifruit comes from China, where it grew wild in the Yangtze River valley for thousands of years before the rest of the world ever tasted it. The fruit we buy in supermarkets today traces back to a handful of seeds carried to New Zealand in 1904, where farmers transformed a wild Chinese vine into one of the most recognizable fruits on the planet.
A Wild Fruit From the Yangtze River Valley
The genus Actinidia, which includes all kiwifruit species, is native to south central and southwest China. China is both the origin and distribution center for kiwifruit, with wild species spread across several geographic zones: the Yangtze River Valley, southeastern China, southwestern China, and parts of the north. The fruit has been part of Chinese culture since at least the Tang Dynasty in the 7th century, when it was called “mihoutao,” meaning “monkey peach.”
Wild kiwifruit vines are woody climbers that can scramble high into forest canopies. The fruit people picked in China for centuries was smaller and less uniform than today’s commercial varieties, but the flavor was similar: sweet, slightly tart, and distinctly tropical.
How Seeds Reached New Zealand
In 1904, Isabel Fraser, the headmistress of Wanganui Girls’ College in New Zealand, visited her missionary sister in China and brought seeds home. She gave them to Alexander Allison, a local farmer who liked growing unusual plants. Allison is credited with growing the first kiwifruit vines in New Zealand, though at the time everyone called the fruit “Chinese gooseberry.”
Several New Zealand growers experimented with the vines over the following decades. The most important was Hayward Wright, an Auckland nurseryman who developed a variety that produced large fruit with excellent flavor and good shelf life. His vines were propagated through grafting and eventually became the dominant commercial variety. The green kiwifruit you see in grocery stores is still called the “Hayward” variety in the industry.
Why It’s Called “Kiwifruit”
The name change happened in 1959, driven by Cold War politics and quarantine rules. Turners & Growers, a major New Zealand export company, had been shipping the fruit to the United States under the name “Chinese gooseberry.” An American client, Norman Sondag, warned them that the name was causing problems at customs. Quarantine officials were suspicious of anything labeled “gooseberry” because berries grown close to the ground could come into contact with soil contaminated by anthrax-causing bacteria.
Jack Turner of Turners & Growers coined the name “kiwifruit,” a nod to the kiwi bird and a term American servicemen stationed in the Pacific during World War II would have associated with New Zealand. The rebrand worked. Within a few decades, New Zealand dominated global kiwifruit exports, and the name stuck worldwide.
Green vs. Gold Varieties
The classic green Hayward kiwi has brown, fuzzy skin and bright green flesh with tiny black seeds. It has a balanced sweet-tart flavor, about 92.7 mg of vitamin C per 100 grams (more than an orange), and 3 grams of dietary fiber.
During the 1990s, New Zealand’s Zespri company developed a gold variety through a natural breeding program in partnership with Plant & Food Research. Gold kiwifruit has smoother, less hairy skin, yellow flesh, and a sweeter, more tropical taste. It packs even more vitamin C: 161.3 mg per 100 grams, nearly twice the green variety. It does have less fiber, at 1.4 grams per 100 grams. An improved version of the gold kiwi also proved tolerant to Psa, a bacterial vine disease that devastated earlier gold plantings.
How Kiwifruit Grows
Kiwifruit grows on vigorous, woody vines that need sturdy support structures. Commercial orchards use either T-bar trellises or pergola systems, both built about 6 feet off the ground. The vines climb and spread across these frames, creating a canopy of leaves and hanging fruit.
One unusual feature: kiwifruit plants are dioecious, meaning male and female flowers grow on separate vines. Only female vines produce fruit, but they need pollen from nearby male vines delivered by bees or other insects. Seed set declines with distance from male vines, so orchards have to be carefully laid out. Green Hayward kiwifruit is particularly demanding, requiring roughly eight times the insect visits of gold varieties for successful pollination.
The vines prefer slightly acidic soil with a pH between 5.5 and 6.0, and they struggle in alkaline soils above 7.2. Hayward vines need a long growing season of 225 to 240 frost-free days. Young shoots are extremely sensitive to cold: temperatures at or below 30°F for just 30 minutes can cause severe damage in spring, and growers have observed total crop loss after a freeze following bud break.
Where Kiwifruit Is Grown Today
China is now the world’s largest kiwifruit producer by volume, a return to its roots. New Zealand remains the dominant exporter, with Italy also a major player. Smaller commercial operations exist in Chile, Greece, France, and parts of the United States, particularly California and the Pacific Northwest.
The reason you can find kiwifruit year-round comes down to geography. In the Northern Hemisphere, harvest runs from late September through early November. In Oregon, Hayward fruit typically isn’t ready until the end of October or early November, after the leaves change color or a few frosts have concentrated the sugars. Southern Hemisphere producers like New Zealand and Chile harvest during their autumn months (roughly April through June), then ship fruit north. This staggered schedule from opposite sides of the equator keeps grocery store bins full in every season.
