Growing Kiwi Vine from Seed vs. Purchased Plants

A Northern Indiana gardener wants to grow kiwi vine (Actinidia species) on a trellis at a mobile home and asks whether seeds from store-bought fruit can be used.

Seed Propagation Reality

• Uncertain viability: Grocery store kiwi may be treated, hybrid, or from varieties unsuited to the climate
• Gender mystery: Kiwi vines are dioecious (separate male/female plants). Both are needed for fruit, and gender can't be determined from seedlings for several years
• Long juvenile period: Seed-grown vines take 3–7 years to flower

Practical Approach

1. Try seeds experimentally: Clean, dry, and stratify (cold treatment) seeds. Keep in darkness. No harm in attempting.
2. Purchase known varieties: Nursery plants cost under $10 and offer known gender, hardiness, and fruiting timelines
3. Select hardy species: Actinidia arguta (hardy kiwi) or A. kolomikta (Arctic kiwi) survive Zone 4–5 winters, unlike fuzzy A. deliciosa

Recommendation

For reliable results, buy a male and female pair of a hardy kiwi variety from a reputable nursery. Use the seed experiment as a learning project, not the primary planting.
