Habitat originel

Woods and thickets. A naturally occurring hybrid, A. quinata x A. trifoliata[200].

Origine géographique

Asie orientale - Japon

Comestibilité

• Fruits - crus [200].
• Sweet but insipid .
• The fruit has a delicate flavour and a soft juicy texture [K].
• The flavour can be enhanced by the addition of a little lemon juice .
• Valued as a novelty, it looks somewhat like a deep-purple coloured sausage .
• The dried young leaves are a tea substitute .

Autres usages

• The peeled stems are very pliable .
• They can be bleached and used in basket making [46, 61].

Culture

• Requires a well-drained moisture retentive soil [200].
• Succeeds in acid or alkaline soils [200].
• Prefers partial shade but succeeds in full sun [200].
• Succeeds on a north facing wall [219].
• Dormant plants are hardy to about -15°c but they can be somewhat tender when young and are best given some protection at this time [200].
• The young growth in spring, even on mature plants, is frost-tender and so it is best to grow the plants in a position sheltered from the early morning sun [K].
• Resentful of root disturbance, either grow plants in containers prior to planting them out or plant them out whilst very young [219].
• A naturally occurring hybrid, A. quinata x A. trifoliata [200].
• Plants are evergreen in mild winters [11, 200].
• They are fast growing and can be invasive [200].
• Plants are not normally pruned, if they are growing too large they can be cut back by trimming them with shears in early spring [202].
• Shy to fruit, it possibly requires some protection in the flowering season - hand pollination is advisable .
• Plants are also possibly self-sterile .
• Les plantes de ce genre sont notamment résistantes aux armillaires (champignons) [200].

Propagation

• Graines - Semez sous chassis dès qu'elles sont mûres .
• Surface sow in a light position [133].
• The seed usually germinates in 1 - 3 months at 15°c [133].
• Stored seed should be given 1 month cold stratification[113, 133] and can be very difficult to germinate .
• When large enough to handle, prick the seedlings out into individual pots and grow them on in light shade in the greenhouse for at least their first winter .
• Plantez les en extérieur à la fin du printemps ou au début de l'été, après les dernières gelées .
• This is a hybrid species and so it will not breed true from seed .
• Boutures de bois mi-mûr, Juillet/Août sous chassis [11, 113].
• The cuttings can be slow to root [200].
• Cuttings can also be taken of soft wood in spring [113].
• Root cuttings, December in a warm greenhouse [113].
• Layering in early spring [1].
• Very easy, the plants usually self-layer and so all you need to do is dig up the new plants and plant them out directly into their permanent positions .
