Exotic Yet Frost-Proof: A Guide to Growing Kiwiberries

Smooth fruits you eat skin-on, and vines that resist brutal frosts. Discover the fascinating world of Actinidia arguta.

When you mention kiwi, most of us picture the brown, fuzzy fruit from the supermarket that requires peeling or eating with a spoon. However, this classic kiwi (Actinidia deliciosa) is very sensitive to frost and difficult to grow in colder climates. Nature, however, offers us a much better, gardener-friendly alternative – the kiwiberry (hardy kiwi), botanically known as Actinidia arguta.

What Makes Kiwiberries So Special?

The kiwiberry is a vigorously growing, woody climbing vine (annual growth can be up to 2 meters) originating in the cold regions of Asia, Siberia, and the Far East. Due to this origin, it has developed extreme frost hardiness – mature plants can easily survive temperatures dropping down to -28 °C.

Kiwiberries are significantly different from the fuzzy ones we know. They are about the size of a large gooseberry or grape. Their surface is perfectly smooth and hairless. Thanks to their thin skin, they do not need to be peeled and are eaten whole, right off the vine. They are true vitamin bombs with huge amounts of vitamin C, antioxidants, and minerals.

Beware of Pollination Rules!

The fundamental rule for successful kiwiberry cultivation is that it is a dioecious plant. This means that to produce fruit, you must plant a female (fruiting) variety and, right next to it, a male plant (pollinator) that does not produce fruit but provides pollen. 

Kiwiberries require a sturdy support (pergola, fence, or trellis). They love fertile, slightly acidic, and well-draining soil. They thrive in sunny to slightly shaded spots protected from strong winds. They do not tolerate drying out, so regular watering is essential. Pruning is similar to grapevines, bearing in mind that the shoots flower and fruit on two-year-old wood.

We present 5 top-tier female varieties that will turn your garden into an exotic paradise.

1. Ananasnaya: A North American Hit with Russian Roots

Although it is one of the most popular varieties in North America, its true origins trace back to Russia. The fruits of 'Ananasnaya' are cylindrical, slightly flattened on the sides, light green with a soft red blush. They reach a weight of 7 to 12 g. They excel in fantastic aromatic flavor, which, as the name suggests, strongly resembles pineapple. It blooms in June and fruits ripen at the end of summer. It is an extremely hardy and prolific vine.

2. Bingo: A Polish Pink-Red Pearl

An exceptional Polish variety created by crossing Actinidia purpurea and Actinidia arguta. 'Bingo' will enchant you not only with its yield but especially with the beautiful appearance of its fruits. They captivate with a unique color ranging from light pink to deep red. Under the skin hides an excellent sweet flesh with fruit weighing 8 - 14 g. From one adult bush, you can harvest dozens of kilograms of this delicacy. It ripens from mid-September to October.

3. Chang Bai Giant: The Giant from China

As the English name suggests, this is a variety originating from China, known for its exceptionally large fruits. The fruit shape is flattened, and the skin color remains deep green. The fruits are larger than other common kiwiberry varieties. The taste of 'Chang Bai Giant' is very sweet and highly aromatic. It blooms in May to June and brings a large harvest in late September and October.

4. Domino: Asian Round-Oval Quality

A reliable Asian variety suitable for home and commercial growing due to its abundant fruiting and berry size. 'Domino' fruits are round-oval, reaching a weight of 12 to 16 g, with smooth greenish-brown skin. Their flavor is excellent, full, and very sweet. The variety grows very vigorously, requires strong support, and ripens in September and October.

5. Geneva: Sweet with a Honey Flavor

The 'Geneva' variety is among the early and highly popular cultivars. It produces cylindrical, side-flattened fruits about 3.5 to 4 cm long with light green skin and an attractive red blush. The fruits can reach up to 20 g. Its absolute advantage is its exceptional taste – it is very aromatic and leaves a delicate honey flavor on the tongue. It is resistant not only to cold but also handles drier periods well.
