Arum maculatum
The purple spotted leaves appear in the spring (April–May) followed by the flowers borne on a poker shaped inflorescence called a spadix. The purple spadix is partially enclosed in a pale green spathe or leaf-like hood. The flowers are hidden from sight, clustered at the base of the spadix with a ring of female flowers at the bottom and a ring of male flowers above them. Above the male flowers is a ring of hairs forming an insect trap. Insects, especially Psychoda spp., attracted to the spadix by its faecal odour and a temperature up to 15 degrees celsius warmer than the ambient temperature, are trapped beneath the ring of hairs and are dusted with pollen by the male flowers before escaping and carrying the pollen to the spadices of other plants, where they pollinate the female flowers. In autumn the lower ring of (female) flowers forms a cluster of bright red berries which remain after the spathe and other leaves have withered away. These attractive orange berries are extremely poisonous.
Is a common woodland plant species of the Araceae family. It is widespread across temperate northern Europe.
