Thunberg grape

The Thunberg grape (lat. Vitis thunbergii) is a perennial woody vine belonging to the Vitaceae family. This species is named after the renowned Swedish naturalist Carl Peter Thunberg. The plant is characterized by high growth vigor, capable of rapidly colonizing vertical supports and creating dense foliage coverage.

The native range of this species is primarily in East Asia, including Japan, China, and the Korean Peninsula. In its natural habitat, the plant is found in forests, on mountain slopes, and along riverbanks, where it utilizes trees and shrubs as natural supports to reach sunlight.

Botanically, the plant is distinguished by five-lobed or three-lobed leaves with characteristic pubescence on the underside. The shoots of the Thunberg grape are highly adhesive due to developed tendrils. Small, inconspicuous flowers are gathered in paniculate inflorescences, and the fruits are small dark berries, which, despite being edible, are rarely consumed due to their high astringency.

The crop has moderate requirements for growing conditions: it prefers well-drained, fertile loams with a neutral to slightly acidic pH. The plant is relatively winter-hardy, although it requires protection from severe frosts in its youth. In terms of agrotechnics, annual sanitary pruning is essential to control the excessive spread of the vine and to shape the crown effectively.

The commercial and practical use of Vitis thunbergii is primarily focused on ornamental gardening and landscape design for the vertical greening of walls, gazebos, and fences. Due to its resistance to several fungal diseases, the species also attracts interest from breeders as a donor of resistance genes for developing hybrid forms of domestic grapevines.

• High growth rate of the vine.
• Resistance to major grapevine diseases (downy and powdery mildew).
• Ornamental foliage during the autumn season.
• Tolerance to various light conditions, including partial shade.
