Comestibilité

• Fruits - crus .
• Sweet but insipid [2, 3, 46, 61, 105].
• 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 more as a novelty, the fruit looks somewhat like a deep-purple coloured sausage [183].
• The fruit is 7 - 13cm long [200].
• The dried young leaves are used as a tea substitute [46, 61, 105, 183].

Usages médicinaux

• The stems are analgesic, antibacterial, antifungal, anti-inflammatory, antitumor. blood tonic, cardiotonic, diuretic, emmenagogue and galactogogue [147, 176].
• Taken internally, it controls gram-positive bacterial and fungal infections and is used in the treatment of urinary tract infections, lack of menstruation, to improve lactation etc [176, 238].
• The stems are harvested in the autumn and dried for later use [238].

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 loamy soil [11, 200].
• Succeeds in acid or alkaline soils [200].
• Prefers partial shade but succeeds in full sun [3, 200].
• Grows well on a north facing wall [219].
• Dormant plants are hardy to about -20°c but they can be somewhat tender when young [200].
• Another report says that this species is not as hardy as A. quinata, only tolerating temperatures down to -10°c .
• 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].
• This species grows very well in S.W. England .
• Resentful of root disturbance, either grow plants in containers prior to planting them out or plant them out whilst very young [219].
• Plants are evergreen in mild winters [11].
• Fast growing, it can be invasive .
• It grows well on deciduous trees [28].
• 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].
• Plants are shy to fruit, they possibly require some protection in the flowering season, hand pollination is advisable [3, 11].
• Plants are probably self-sterile[182], if possible at least 2 plants should be grown, each from a different source .
• The flowers are sweetly scented [245].
• The fruits are sold in local markets in Japan [46].
• The ssp .
• A. trifoliata australis .
• (Diels.)Rehd. is used medicinally in China [176].
• 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 .
• 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 .
