Kiwi

The kiwifruit is a small, fuzzy brown ovate fruit with vivid emerald-green flesh and tiny black seeds, valued worldwide for its tangy-sweet tropical flavor and remarkably high vitamin C content.

History & Origins

The species is native to the Yangtze River valley of southern China, where it grew wild and was collected as 'mihoutao' (macaque fruit) for centuries before being brought into cultivation. In 1904, Mary Isabel Fraser brought seeds to New Zealand, where horticulturist Alexander Allison germinated them and growers developed the commercial 'Hayward' cultivar by the 1930s. New Zealand exporters rebranded the fruit as 'kiwifruit' in 1959 to capitalize on national identity during Cold War-era marketing.
