Wild Arum is a
native
perennial plant of the UK, typically found growing in woodland, hedgerows and shady ground, to a mature height of up to 50cm.
The flowering structures of the Wild Arum act as an elaborate 'fly trap' to ensure effective pollination. Wild Arum attracts Owl Midges and other flies for pollination by mimicking the smell and heat generated by rotting plants and dung. The centre of the plant can rise to 15 degrees Celsius above the surrounding temperature. Once attracted, landing flies slip into the base of the flower where they are trapped from escape by downward pointing hairs, and they both pass on and take up pollen. These hairs eventually shrivel, releasing the flies to visit another plant to exchange pollen for pollination.
Botanic classification and naming: Wild Arum is a member of the Arum (Araceae) family. The genus name
'Arum' identifies the plant as a Arum, a plant with tiny flowers borne on a trucheon-like 'spadix', sheathed within a 'spathe' and its species name 'maculatum' means 'spotted (leaves)'.
