A small, green to purple skinned, [[fruit]] similar to [[kiwifruit]], '''hardy kiwifruit''' is an edible, berry-sized [[fruit]] of a [[Cultivar Group]] of the [[woody plant|woody]] [[vine]] '''''Actinidia arguta'''''. Often sweeter than the [[kiwifruit]], hardy kiwifruit can be eaten whole and need not be peeled. Thin-walled, its exterior is smooth and leathery, providing a deceiving contrast to the fuzzy, brown exterior of its larger sibling fruits.

* ''Ananasnaja (Anna)'' - Said to be an outstandingly reliable bearer of relatively large fruit (to 1" X 1-1/2"). Fruit is said to be not quite as sweet as that of some other cultivars. Appears to be more resistant to spring frosts than other Actinidias and will supposedly produce blossoms on re-growth if the original growth is killed by frost in spring.

Appears to be more resistant to spring frosts than other Actinidias and will supposedly produce blossoms on re-growth if the original growth is killed by frost in spring. A medium-size fruit, 4cm long and 2½cm in diameter{{pfaf183}}. Juicy and sweet with a distinct pineapple-like aroma and flavour{{pfaf183}}. Possibly a hybrid with A. kolomikta, it is a reliable bearer that often produces fruit in bunches like grapes{{pfaf183}}. A very hardy plant, tolerating temperatures down to -35°c when fully dormant{{pfaf183}}.
*''Ananasnaya''(different than above, with a Y)- Fruit is said to have a pleasant pineapple-like flavor. Appears to be a different cultivar from 'Ananasnaja', above. Can bear over 200 lbs. of fruit.

* ''Dumbarton Oaks'' - Fruit is said to be especially sweet.
* ''Dumbarton Oaks'' - Fruit is said to be especially sweet.
* ''Geneva'' - Bears fruit to about 1" long; ripens here in late September and October. From the Geneva, NY Agricultural Experiment Station. Very vigorous and reliably hardy.
* ''Geneva'' - Bears fruit to about 1" long; ripens here in late September and October. From the Geneva, NY Agricultural Experiment Station. Very vigorous and reliably hardy.
* ''Issai'' (2 distinct self-fruitful cultivars from Japan) - Bears fruit to about 1" long; ripens here in late September and October. Very vigorous and reliably hardy here.
* ''Issai'' (2 distinct self-fruitful cultivars from Japan) - Bears fruit to about 1" long; ripens here in late September and October. Very vigorous and reliably hardy here. A long fruit, up to 4cm in diameter, it is sweet with a good flavour and high quality{{pfaf183}}. The fruit is seedless when it is not pollinated{{pfaf183}}. This cultivar can produce fruits in the absence of a male pollinator, often in the first year after grafting, but yields will be increased if the plant is pollinated{{pfaf183}}.
* ''Ken's Red''
* ''Ken's Red''
* ''Langer'' - Bears medium-size fruit of fine quality{{pfaf183}}. The original plant is from a homestead high in the Cascade Mountains where it had to endure summer droughts, deep snow, severe cold and wind, and other adverse conditions{{pfaf183}}.
* ''Michigan State'' - A female selection from Michigan State University. Well regarded for fruit size and quality.

* ''119-40B'' - A self-pollinating selection from the Arnold Arboretum in Massachusetts. Appears to be a typical A. arguta in other respects (unlike 'Issai'), and will probably be useful for pollinating other A. arguta cultivars.

Cuttings for true offspring. Can be grown from seed, but outcome of fruit quality (and sex) is uncertain. In areas where the regular kiwifruit will grow, scions of the hardy kiwi may be grafted directly onto kiwifruit rootstock. Otherwise, one must either root their own from hardwood or greenwood cuttings or buy established plants.

Seed - sow spring in a greenhouse{{pfaf133}}. It is probably best if the seed is given 3 months stratification{{pfaf113}}, either sow it in a cold frame as soon as it is ripe in November or as soon as it is received. Fresh seed germinates in 2 - 3 months at 10°c, stored seed can take longer{{pfaf133}}. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in light shade in the greenhouse for at least their first winter. When the plants are 30cm or more tall, plant them out into their permanent positions in late spring or early summer, after the last expected frosts{{pfafK}}. Most seedlings are male{{pfaf126}}. The seedlings are subject to damping off, so they must be kept well ventilated{{pfaf113}}. Cuttings of softwood as soon as ready in spring in a frame{{pfafK}}. Cuttings of half-ripe wood, July/August in a frame. Very high percentage{{pfaf113}}. Cuttings of ripe wood, October/November in a frame.
