The fruit is a large berry containing numerous small seeds; in most species, the fruit is edible. In particular, this genus is known for the species "Actinidia deliciosa", the kiwifruit or Chinese gooseberry, and for the hardy ornamental "A. kolomikta". "Actinidia" macrofossils have been recovered from the late Zanclean stage of Pliocene sites in Pocapaglia, Italy. The 40–60 species of "Actinidia" include: Kiwifruit is a cultivar group of "A. deliciosa", and hardy kiwi is the species "Actinidia arguta", which has small
Kiwi often kill or maim kiwi. Habitat destruction is another major threat to kiwi; restricted distribution and small size of some kiwi populations increases their vulnerability to inbreeding.

The Māori traditionally believed that kiwi were under the protection of Tane Mahuta, god of the forest. They were used as food and their feathers were used for kahu kiwi—ceremonial cloaks.
