Habitat originel

The origin of this plant is uncertain, it is possibly a hybrid, A. ptarmica x A. macrocephala[187].

Origine géographique

Europe - Greece.

Comestibilité

• Feuilles - crues ou cuites .
• The initial flavour is mild and pleasant, though it becomes stronger and aromatic when the leaves are chewed, and leaves a tingly sensation in the mouth [K].
• They make an acceptable addition to mixed salads, the plant is very productive, though the leaves are rather small and fiddly to pick in quantity [K].
• They are also used in soups, stews etc., and as a flavouring in potato salad etc [183].
• The aromatic leaves are used as a tea substitute [183].

Culture

• Succeeds in most soils but prefers a well-drained soil in a sunny position [1, 200].
• It also succeeds in partial shade [187].
• Plants live longer in a poor soil [200].
• Established plants are very drought tolerant, they can show distress in very severe droughts but usually recover [190].
• Plants succeed in maritime gardens [233].
• Robuste jusqu'à environ -20°C [187].
• An excellent plant to grow in a large pot, the long stems will tend to arch down and continue to flower for a long time [244].
• The leaves have a pungent aroma, especially when the plant is grown in a hot sunny position [245].
• The plant is intermediate between A. millefolium and A. ptarmica in its characteristics [233].
• There is at least one named variety, selected for its ornamental value [233].
• S'hybride librement avec les autres membres du genre [200].

Propagation

• Graines - semez au printemps ou au début de l'automne sous chassis [133].
• Les graines germent généralement en 1-3 mois [133].
• Quand elles sont suffisamment développées pour être manipulées, repiquez les jeunes pousses en pots individuels et plantez les en extérieur durant l'été .
• If this species is a hybrid it might not breed true from seed .
• Division au printemps ou à l'automne .
• Très facile, les divisions peuvent être plantées directement à leur place définitive .
• Basal cuttings of new shoots in spring .
• Very easy, collect the shoots when they are about 10cm tall, potting them up individually in pots and keeping them in a warm but lightly shaded position .
• They should root within 3 weeks and will be ready to plant out in the summer .
