Actinidia deliciosa Cultivation spread from China in the early 20th century when seeds were introduced to New Zealand by Isabel Fraser, the principal of Wanganui Girls' College, who had been visiting mission schools in China. The seeds were planted in 1906 by a Wanganui nurseryman, Alexander Allison, with the vines first fruiting in 1910. People who tasted the fruit thought it had a gooseberry flavour, so began to call it the Chinese gooseberry, but being from the genus "Actinidia", it is not related to the gooseberry family, Grossulariaceae. The familiar cultivar "Actinidia deliciosa" 'Hayward' was developed by Hayward Wright in Avondale, New
Gooseberry development stage. Other potential threats are V-moth ("Macaria wauaria") and gooseberry sawfly ("Nematus ribesii"). "Nematus ribesii" grubs will bury themselves in the ground to pupate; on hatching into adult form, they lay their eggs, which soon hatch into larvae, on the underside of gooseberry leaves. Insecticides used in the 19th-century against these included tar water, weak solutions of carbolic acid, and powdered hellebore, which worked against magpie moths and V-moths as well as gooseberry sawflies. (Foxglove and tobacco infusions were also sometimes used.) A 2008 study concluded that a solution of magnesium sulfate applied to a bush's leaves has a
