The Japanese Raisin Tree (Hovenia dulcis) is a fascinating and elegant tree native to East Asia. Known for its unique edible fruit stalks that become sweet and raisin-like when dried, it offers both culinary and ornamental value.
In summer, it blooms with delicate, honey-scented white flowers that attract bees, followed by twisted peduncles (fruit stalks) that turn brown and sugary as they mature. The fruit and flower display, combined with its graceful shape, make this species a favorite among collectors and edible landscape enthusiasts.
This hardy deciduous tree can thrive in a variety of soil types and climates, making it an excellent choice for USDA Zones 5–9.
