'''''Actinidia''''' {{IPAc-en|ˌ|æ|k|t|ᵻ|ˈ|n|ɪ|d|i|ə}}<ref>''Sunset Western Garden Book,'' 1995:606–607</ref> is a genus of [[woody plant|woody]] and, with a few exceptions, [[dioecious]] plants native to temperate eastern [[Asia]], occurring throughout most of [[China]], [[Taiwan]], [[Korea]], and [[Japan]], and extending north to southeast [[Siberia]] and south into [[Indochina]]. The genus includes [[shrub]]s growing to {{convert|6|m|abbr=on}} tall, and vigorous, strong-growing [[vine]]s, growing up to {{convert|30|m|abbr=on}} in tree canopies. They mostly tolerate temperatures down to around −15°C (5°F), and some are much hardier.
 
 
 
The [[leaf|leaves]] are alternate and simple, with a dentated margin and a long [[Petiole (botany)|petiole]]. The [[flower]]s are solitary or in axillary [[Cyme (botany)|cymes]], usually white, with five small [[petal]]s. Most of the species are [[plant sexuality|dioecious]] with separate male and female plants, but some are [[monoecy|monoecious]]. The [[fruit]] is a large [[berry (botany)|berry]] containing numerous small [[seed]]s; 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 ''[[Actinidia kolomikta|A.&nbsp;kolomikta]]''.
 
 
 
==Fossil record==
 
''Actinidia'' macrofossils have been recovered from the late [[Zanclean]] stage of [[Pliocene]] sites in [[Pocapaglia]],  [[Italy]].

== Uses ==
 
Kiwifruit is a [[cultivar group]] of ''A. deliciosa'', and hardy kiwi is the species ''[[Actinidia arguta]]'', which has small fruit weighing {{convert|10|-|15|g|abbr=on}}, with green edible skins and green flesh; it is hardier than ''A.&nbsp;deliciosa''. Some species are grown as [[ornamental plant]]s, notably ''A.&nbsp;kolomikta''. 
 
 
 
In Japan, ''[[Actinidia polygama]]'' ([[silver vine]]) is noted for having an effect on cats much like that of [[catnip]].  It is mentioned in the saying 猫にまたたび、女郎に小判 (''neko ni matatabi, jorō ni koban'', "[[silver vine]] to a cat, a coin to a prostitute"), meaning to put someone in a good mood by providing that which they most desire.
 
 
 
''A. kolomikta'' is the hardiest species (to about -40°), and has distinctive white- and pink-[[variegation|variegated]] foliage even on wild plants, an unusual phenomenon. Its fruit is very small, weighing {{convert|8|g|abbr=on}} or less.
