Grow one of the world's most unusual and rewarding fruit trees from seed. The Japanese Raisin Tree is a hardy deciduous tree prized for its unique swollen fruit stalks, which become sweet and edible when fully ripe. Despite its name, it does not produce raisins but develops crisp, naturally sugary stalks with a flavour reminiscent of pears, raisins and caramel. These seeds are ideal for growers wanting to raise this fascinating and productive tree from seed.

Seed Type: Fresh Japanese Raisin Tree seeds.
Origin: China, Japan and Korea.
Growth Habit: Fast-growing deciduous tree reaching approximately 8–15 metres at maturity. An attractive shade tree with a broad canopy, suitable for home gardens, orchards and lifestyle properties.
Germination: Soak seeds in warm water for 24 hours before sowing 10–15 mm deep in a free-draining seed-raising mix. Keep warm (20–25°C) and consistently moist. Germination typically occurs within 4–10 weeks, although some seeds may benefit from a short period of cold stratification.
Climate: To get a head start, or if you are in colder climates, start growing your seeds indoors so they are well established before summer. In the North Island, Japanese Raisin Tree grows well in a sunny position with fertile, well-drained soil. In the South Island, it is well suited to most regions and tolerates winter cold once established, although young plants should be protected from severe frosts.
Fruit: Produces small seed capsules attached to swollen, fleshy stems. It is these unusual stems—not the fruit itself—that become sweet and edible as they mature.
Taste: The swollen fruit stalks have a crisp, chewy texture with a naturally sweet flavour often compared to raisins, pears, honey and caramel. They are delicious eaten fresh or dried, where the sweetness becomes even more concentrated.
Flowers: Produces clusters of small creamy-white, fragrant flowers during summer that attract bees and other beneficial pollinators.
Fruiting: Typically begins producing edible fruit stalks within 5–8 years from seed under good growing conditions.
Care: Prefers full sun to partial shade, fertile free-draining soil and regular watering while establishing. Once mature, it is hardy, drought tolerant and relatively low maintenance.
