Tara Vine Plant Information

Tara Vine grows in the following 5 states:

Maine, Massachusetts, New Jersey, New York, Ohio

The fruit are referred to as Hardy kiwifruit, kiwi berry, arctic kiwi, baby kiwi, dessert kiwi, grape kiwi, northern kiwi, or cocktail kiwi and are edible, berry or grape-sized fruit similar to kiwifruit in taste and appearance, but are green, brownish, or purple with smooth skin, sometimes with a red blush. Often sweeter than the kiwifruit, hardy kiwifruit can be eaten whole and need not be peeled. Thin-walled, its exterior is smooth and leathery.Actinidia arguta (hardy kiwi) is a perennial vine native to Japan, Korea, Northern China, and Russian Siberia. It produces a small fruit resembling the kiwifruit.

The fast-growing, climbing vine is very hardy (hence the name hardy kiwi), and is capable of surviving slow temperature drops to -34C (-30F), although young shoots can be vulnerable to frost in the spring. The vines need a frost-free growing season of about 150 days, but are not damaged by late freezes, provided that temperature changes are sufficiently gradual to allow plants to acclimate. Indeed, a period of winter chill is necessary for successful cultivation. However, rapid freezes will kill off buds and split vines. The vines can also be grown in low-chill areas.
While hardy kiwi may be grown directly from seeds (germination time is approximately one month), it is also possible to propagate from cuttings. Hardy kiwi cuttings may be grafted directly onto established kiwifruit rootstock, or rooted themselves.
In domestic cultivation, a trellis may be used to encourage horizontal growth for easy maintenance and harvesting; however, vines grow extremely quickly and require a strong trellis for support. Each vine can grow up to 20 feet in a single season, given ideal growing conditions. For commercial planting, placement is important: plants can tolerate partial shade but yields will be optimized with full sunlight. Hardy kiwi vines consume large volumes of water; therefore, they are usually grown in well-drained acidic soils to prevent root rot.
For vines to bear fruit, both male and female plants must be present to enable pollination. A male pollinator can enable six female producers to fruit. Flowering typically occurs in late spring (May in the Northern Hemisphere) starting in the third year of growth. If flowers become frost-burned, however, no fruit production will occur during the remainder of the year.
An autumn harvest is standard among all varieties; within this, actual harvest times are highly dependent on local climate and the specific cultivar grown. Each individual vine can produce up to 100 pounds of fruit per year, but average annual yield is approximately 50 pounds per vine. Both fruit size and total yield are highly cultivar-dependent. Fruits left to ripen on the vine have an 18 to 25 percent sugar content at time of harvest.
Hardy kiwi vines are vulnerable to several botanical diseases, including phytophthora crown and root rot (the most serious problem), botrytis rot, and sclerotinia blight. Vines are also vulnerable to pest infestations, including root knot nematodes, two-spotted spider mites, leaf rollers, thrips, and Japanese beetles. Cats can also pose a problem, as they are attracted to a catnip-like smell that is produced by the hardy kiwi vines. Cats have been known to destroy vines and dig up roots in search of the source of the scent.
Attempts to commercialize the fruit have been historically unsuccessful due to its short shelf-life and sporadic tendencies to ripen. However, attempts are being made to bring the fruit to greater bear, and commercial production initiatives are underway on a small scale in South America, New Zealand, Europe, Canada, and the United States (in Oregon, Washington, and central Pennsylvania).
Actinidia arguta was first described by Philipp Franz von Siebold and Joseph Gerhard Zuccarini in 1843 as Trochostigmaargutum. It was then moved to the genus Actinidia in 1867 by Friedrich Anton Wilhelm Miquel after the invalidly published suggestion by Jules mile Planchon to move the species.
The species consists of three varieties:
Actinidia arguta var. giraldii was originally described by Ludwig Diels at the species rank (Actinidiagiraldii) in 1905, but was later reduced to a variety of A.arguta in 1972 by Vladimir Nikolaevich Voroschilov.Actinidiaarguta var. hypoleuca was originally described at the species rank (Actinidiahypoleuca) by Takenoshin Nakai in 1904, but reduced to a variety of A.arguta in 1980 by Siro Kitamura.
Actinidia arguta had been placed in section Leiocarpae and series Lamellatae, but this current infrageneric classification is unsupported. A 2002 study of the nuclear DNA internal transcribed spacer sequence and the plastid matK gene sequence for cladistic analysis revealed the current circumscription of the sections to be polyphyletic, with A.arguta forming a clade with A.melanandra near the base of the phylogenetic tree.
The most popular cultivars include Ananasnaya, Geneva, MSU, Weiki, Jumbo Verde and Rogow. A commonly sold self-fertile hybrid is the Japanese cultivar Issai (arguta x rufa).
Actinidia arguta has been cultivated by hobbyists, and more recently commercially, in the northeastern United States since at least the early 1900s with no significant impact on the region's forests noted, until recently. Due to rampant overgrowth and "complete domination of mature trees" at sites western MA and Coffin Woods, Long Island, NY, A. arguta vines of unknown genotype and provenance are now reported by groups including Mass Audubon and Vermont Invasives to be invasive. Whether such localized sites indicate an invasive risk for the region as a whole is controversial, however, given the long history of this widely distributed and cultivated species in the northeastern United States. Since successful invasions of non-native species can occur gradually over time, however, these reported sites warrant further investigation and suggest the need for more widespread monitoring.
Currently, the USDA Forest Service Section 3B Eastern Region lists A.arguta in Category 4 Plants for local concern and monitoring. These plants are non-native species that occur locally in the region. By their assessment, it is not currently known if it can be especially invasive, but the species was recommended for future monitoring. The Massachusetts Invasive Plant Advisory Group lists A.arguta as a species that did not meet the criteria at that time, citing a lack of evidence or deficiency of data on its reproductive ability and potential escape from cultivation.
Macrofossils of Actinidia arguta from the early Pliocene epoch have been found in Western Georgia in the Caucasus region.
