Kiwis are a type of fruit native to the mountains and hillsides of Southwest China. They are classified as berries. The most popular type of kiwi is the Hayward kiwi, named after Hayward Wright, who popularized kiwis in New Zealand in the 1920s. Hayward kiwis are oval shaped. They have fuzzy brown skin, green flesh, and tiny black seeds. Kiwis are exceptionally high in vitamin C. A 3.5-ounce (100-gram) kiwi provides more than 80% of the average daily vitamin C requirement.
