Croquignolet, alangui, mais avec un GROS avantage: il aime..L'EAU!!!!! (Lo? )
Son petit nom, c'est Allium macranthum. Voilà ce qu'en dit la pépinière où je l'ai acheté (en soldes! ):
"Narrow flattened basal leaves are produced with up to three short flower stems, each carrying between five and twenty conical, pink, purple or violet-purple, pinch-nosed flowers with lemon anthers.
Damp soil is best, not a pond edge, but something rich and humus filled that holds water but drains freely, but that is perfection and the plant is tolerant (and almost evergreen by the way). "
(traduction sur demande! )

Quelqu'un l'a-t-il déjà essayé? Est-il envahissant?????
