Product information "Raisin Tree 'Korinth'"

A raisin tree – at first one may not believe the miracle promised by the name of the raisin tree, Hovenia dulcis. But fortunately, the yield of the raisin tree starts very quickly for a tree: after only 2-3 years, the first blossoms appear and the elongated pseudo-fruits form out of the flower stalks, which give the sweet Japanese raisin tree its name. This is really a small or bigger miracle! Hovenia dulcis (the botanical name “dulcis” also refers to the sweetness) is hardy during the winter; it loses its foliage during the winter, but is also ornamental during dormancy thanks to its dark violet, shiny bark. If you count the ornamental value of the large, heart-shaped leaves and then think of the sweet pseudo-fruits (the tree raisins), there is probably really no stopping yourself: I also have to have this still fairly unknown fruit tree in my garden!
Short Description of the Raisin Tree ‘Korinth’
Flowers: In May to June, the terminally formed, irregularly arranged inflorescences bloom with several, 6-8 mm large, creamy white to slightly greenish, fragrant flowers.
Fruits: The true fruits produced from the flowers contain three seeds and are inedible; but immediately after flowering, the asymmetrically arranged, picturesque flower stalks begin to swell and the result is the approximately 3 cm long, sweet pseudo-fruit, which also smells and has a sweetish taste.
Maturity/harvest: The pseudo-fruits ripen from September to October; they can be eaten raw, cooked or dried.
Flavour: Dried fruits taste like raisins, which gave the tree its name “raisin tree”. The taste is sweet, similar to pears. The flavour is more reminiscent of Nashi than European pears. This comparison is probably quite appropriate and finds its equivalent in the “fruit chemistry”: the flavonoid dihydromyricetin is found in both Asian pears (Nashis) and in the pseudo-fruits of the raisin tree; this is said to have an effect against hangovers after excessive alcohol consumption (see below).
Use: The pseudo-fruits can be enjoyed fresh and dried; they and the extract obtained from them are also said to have effects against hangovers. In Asian medicine, the wood and bark are put into water and poured into tea. Concentrated extracts are also used as natural sweeteners. The hard wood of Hovenia dulcis is very popular and is also called Japanese mahogany.
Plant spacing: 3-5 metres.
Location/growth: The location should be sunny to partially shaded. The raisin tree loves rather light, humus soil. Hovenia dulcis grows slowly, but can reach up to five or even more metres after 25-30 years. The shrub Hovenia dulcis remains naturally more compact in containers and starts producing fruits or pseudo-fruits after only 2-3 years.
Pollination: Self-fertile; the flowers have female and male organs and can fertilise themselves.
Training/pot cultivation: When planting in a garden, a solitary position is recommended, where the beautiful, black-violet bark, the summer green, large, shiny, heart-shaped leaves are highly visible. If there is not enough room for a tree that can grow 5-10 m in height, Hovenia should be grown as a large, multi-stemmed shrub, which spreads its vigour to several shoots and keeps the shrub more compact. Thanks to the beautiful leaves, the black-violet wood and the early fertility, the raisin tree is also interesting as a container plant (also multi-stemmed).
