Actinidia five small petals. Most of the species are dioecious with separate male and female plants, but some are monoecious. 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
Kiwifruit learn to prefer other species of flowers actively, as the kiwi flowers don't have nectar. To deal with this, some producers blow collected pollen over the female flowers. Most common, though, is saturation pollination, where the bee populations are made so large (by placing hives in the orchards at a concentration of about 8 hives per hectare) that bees are forced to use this flower because of intense competition for all flowers within flight distance. This is also increased by using varieties specifically developed for pollination. Kiwifruit is picked by hand and commercially grown on sturdy support structures, as it
