General Info – Japanese Raisin, Hovenia, Oriental Raisin Tree

Native to the cool subtropics and warm, humid temperate climates of Subtropical East Asia, the Japanese Raisin tree is a distinctive species that bears sweet, edible fruit stalks.
True to its name, these fruit stalks boast a striking resemblance in taste to Raisins, characterized by a rich sweetness with hints reminiscent of Dates. The plump, fleshy stalks of the infloresences, technically known as peduncles, reach their pinnacle of flavour when dried, allowing their sugars and nuanced taste to intensify, evoking notes of Pear, Clove, and Cinnamon. Beyond being a delectable sweet treat, Japanese Raisins can also be added to wines, preserves or candies. While fresh stalks have a limited shelf life, once dried, they will last for several months. Fruit ripen across June to September
Japanese Raisin trees exhibit a graceful, shapely form and are prized for their ornamental value, rapidly ascending to heights of up to 10 metres, and under optimal conditions, reaching towering heights of 25 metres. Displaying a single trunk and a gracefully rounded canopy, these trees possess a handsome form and can be effectively pruned to size. Belonging to the Buckthorn Family (together with Jujube), Japanese Raisins boast attractive ovate leaves with a glossy sheen, accompanied by stunning cream-coloured inflorescences, rendering them an impressive addition to any landscape as a specimen tree.
Due to their rapid growth and adaptability to diverse climates, Japanese Raisins are favoured for their versatility, yet they also pose a potential risk of invasiveness. As deciduous trees, they thrive best when exposed to full sunlight, while their soil preferences are for free-draining conditions, though they are forgiving of variations in pH and fertility. During their dormant phase, Japanese Raisin trees exhibit remarkable cold hardiness, enduring temperatures plummeting to -15 degrees Celsius, though precautions are warranted during late frosts to safeguard tender spring growth. Young plants are especially vulnerable in their early stages and will significantly benefit from protection, especially in marginal climates.
For those with the space, the Japanese Raisin tree offers a distinctive fruiting experience alongside the allure of a rapidly growing, ornamental shade tree.
