Ginkgo Seed Viability and Sex Determination: Low Odds, Long Wait

Ginkgo biloba Seed Propagation Realities

Seed viability is short: a few months at room temp, up to 8 months with special storage.
5-year-old seeds are almost certainly dead.
Sex cannot be determined until trees flower (20+ years).

For a meaningful heirloom, buy a grafted male cultivar (fruitless).
