Plant Profile: Actinidia melanandra

The Purple or Red Kiwi is a deciduous climbing vine characterized by its smooth stems and green leaves, which display a bluish-green hue on their undersides. This plant is dioecious, meaning it has distinct male and female varieties, both of which are essential for fruit production. A single male plant can effectively pollinate up to eight female plants. To identify the sex of your plants, observe the flowers in spring. Focus on the center of the blooms, where you'll find the anthers—oval structures at the end of a filament. If the anthers are covered in pollen and there are no other structures present, the plant is male. Conversely, if you see white stigmas, which are longer than the anthers, alongside a few yellow anthers, the plant is female.

Although the fruit is edible, it is not commonly found in stores due to its limited shelf life. This vine is sensitive to frost and should be planted in a sunny location with proper support for climbing. Occasionally, it may be mislabeled in nurseries as Actinidia melandra.

For successful fruiting, both male and female plants must be present, and full sun exposure is crucial for optimal yield. Additionally, protect the plants from strong winds.

If you plan to propagate from seeds, it's important to stratify them for three months before planting. Fresh seeds typically germinate within two to three months, while stored seeds may take longer. Once the risk of frost has passed, seedlings can be transferred to their permanent spots, though most seedlings tend to be male. Alternatively, softwood cuttings can also be used for propagation.

In terms of pests and diseases, this plant does not face significant issues, although young leaves can be vulnerable to frost damage.

For comparison, you might look at Actinidia kolomikta or Actinidia chinensis.
