Survives zone 7 through 9

Harvest calendar

Best planted in early spring after your last frost, or in fall before the ground freezes, depending on your climate.

Not a single well-defined hybrid — 'green' (A. deliciosa) and 'gold' (A. chinensis) kiwi lines are genetically very close (over 81% shared alleles) with documented natural introgression between them, and current taxonomy treats deliciosa as a variety within chinensis rather than a separate species. Breeders do deliberately cross the two lines, but none of the well-known commercial cultivars ('Hayward', 'Hort16A', 'Gold3', SunGold) is actually a documented direct cross of both — each sits within one parent line or the other. Treat 'hybrid kiwi' as shorthand for that close breeding relationship, not a specific plant.

Vine

Edible part

Fruit

Ripens

Late Aug–Oct

Mature size

Vine 8–10 m; strong trellis. Container short-term only

Light

Full sun

Soil pH

5.0–6.5 (slightly acid)

Environment

Garden origin

Native range

No wild range — a deliberate interspecific cross of A. deliciosa and A. chinensis, made in cultivation to combine the hairy vine's hardiness with the yellow-fleshed species' flavour and earliness.

Status

Cultivated

Years to fruit

3–5 yrs

Growth speed

Very fast — several metres of new growth a season on an established vine

Spacing

400 cm (157 in) apart — about 16 m² (172 sq ft) per plant

Leaf shape

Large, alternate, broadly ovate to almost round, 10–20 cm across, on long petioles — hairy beneath, and intermediate between the two parents in texture.

Root system

Thick, fleshy and shallow, densest in the top 30–60 cm and spreading sideways rather than down. This is the plant's weak point: fleshy roots plus a very high transpiration rate make it exceptionally intolerant of waterlogging, and saturated soil is exactly what Phytophthora crown and root rot needs. Plant on a slope or a raised bed, never in a hollow.

Fruit description

Oval berry 5–8 cm long, intermediate between its parents: less densely bristled than a fuzzy kiwi and often yellow-fleshed like A. chinensis, sweeter and lower in acid than the supermarket green fruit. Ripens mid-autumn and stores for weeks.

Propagation

Semi-ripe or softwood cuttings under mist, or grafting for named cultivars. Seed germinates readily but is close to useless for a crop: sex is not visible until the vine first flowers, several years on, so a seedling batch is a lottery of males and females.

Pollination

DIOECIOUS — needs male and female plants
