Actinidia arguta (eastern Asia)
Habit: Twining, 5-12 m tall; fast-growing, 60-100 a year, very quickly anchored.
Flowers: White, usually dioecious, after leaves open; stamen crimson, slightly fragrant; June.
Fruits: Elongated, up to 2 cm, ovoid, like berries; green, sticky and sweet when fully ripe, best in marmalade.
Leaves: Elliptical to cordate, coarse, with very bent leaf margins, green on both sides; strong yellow in autumn, September to beginning of October.
Roots: Shallow and intense, pavements that are too close are lifted.
Demands: Sun to semi-shade; tolerant of heat, otherwise warm to cool, frost hardy; low to high humidity; resistant to urban pollution; very robust species.
Soil: Dry to moist; slightly acidic to alkaline, sandy-loamy to loamy.
Note: Actinidia arguta deserves to be planted more often. The sweet-sour fruits have 13 times more vitamin C than a lemon. The plant is dioecious, thus both sexes must be planted.
Our tip: In mixed beds, Actinidia arguta should be cut hard as neighbouring trees and shrubs would otherwise be suffocated.
Hardiness: Zone 5b
