description_en: Genus of 26 species of mainly spring-flowering, tuberous perennials found in a range of partially shaded habitats in S. Europe, N. Africa, and W. Asia to the W. Himalayas. They have often attractively marked leaves, which may be spear-, arrow-, or heart-shaped, and which are normally produced in late autumn or winter. Large spathes enclose thin spadices of tiny flowers, either sweetly or unpleasantly scented; these are followed by spikes of red or orange berries. All parts may cause severe discomfort if ingested, and the sap may irritate skin on contact. Some species are good foliage plants for growing with shrubs. The leaves of A. italicum ’Marmoratum’ are often used in flower arrangements. In frost-prone areas, half-hardy species are best grown under glass.

hardiness_en: Fully hardy to half hardy.

cultivation_en:

propagation_en: Sow seed in autumn: remove the outer pulp from the berries (it may be caustic) and sow seed in containers in a cold frame. Divide clumps of tubers after flowering.

pests_en: Trouble free.
