The Japanese Raisin Tree is a quick-growing deciduous tree with an upright open growth habit, with spreading to drooping branches. The edible ‘raisins’ are not a fruit but a swollen flower stalk. Once the flower has been pollinated, the seed and stalk develop. The flower stalk swells and becomes fleshy and lumpy, reddish brown in colour. The seed pod is round and small but inedible. In autumn, the ‘fruit’ will drop from the tree when ripe, or they can be hand-picked. The swollen stalks can be eaten fresh or added to dishes where you use dried fruit. Can be stored (up to 2 months), where the flavour will improve. Gather the freshly dropped bunches in a paper bag and store them in the hot-water cupboard.
Known to be free of any significant pests and diseases. No pruning is required; the lower branches will drop as the tree grows.
