Comestibilité

• Fleurs - crues [K].
• The flowers are up to 5cm in diameter[219], they have a mild, slightly sweet flavour and a slightly mucilaginous texture [K].

Culture

• Requires a sunny position or part day shade in a fertile well-drained soil [200].
• Dislikes drought [200].
• This species is only hardy in the mildest areas of Britain, tolerating temperatures down to between -5 to -10°c when given the protection of a south or south-west facing wall [11, 184, 200].
• Plants are often deciduous in cold winters [219].
• A deep mulch in winter and tying in growth to the wall will maximise protection in winter [200].
• If the plant is cut back by cold weather, it will normally resprout from the base in the spring and can flower on the current year's growth [202].
• Plants tend to be short-lived in Britain, dying suddenly without any apparent cause .
• This is probably because they flower so profusely that they die of exhaustion [11].
• They produce an abundance of fertile seed, however, and this normally breeds true to type, though it will hybridise with the closely related A. vitifolium if this species is nearby [11].
• Dead-heading plants to prevent seeding can enhance longevity [200].
• This species is closely related to A. vitifolium [11].
• Tip-prune young plants to promote a bushy habit, older plants can be cut back hard annually in spring if required [200].
• Les plantes de ce genre sont notamment résistantes aux armillaires (champignons) [200].

Propagation

• Graines - semez au printemps sous serre [200].
• Germination should take place within a few weeks .
• Once the seedlings are large enough to handle, prick them out into individual pots .
• Grow them on for at least the first winter in a greenhouse and plant out in late spring or early summer, after the last expected frosts .
• Cuttings of young shoots, June in a frame [200].
• Grow on in the greenhouse for their first winter and plant out in spring after the last expected frosts .
• Boutures de bois mi-mûr, Juillet/Août sous chassis [200].
• Grow on in the greenhouse for their first winter and plant out in spring after the last expected frosts .
