Arum maculatum is a woodland flowering plant species in the family Araceae. It is widespread across most of Europe, as well as Turkey and the Caucasus. It is known by an abundance of common names including snakeshead, adder’s root, arum, wild arum, arum lily, lords-and-ladies, devils and angels, cows and bulls, cuckoo-pint, soldiers diddies, priest’s pintle, Adam and Eve, bobbins, naked girls, naked boys, starch-root, wake robin, friar’s cowl, sonsie-give-us-your-hand, jack in the pulpit and cheese and toast. The name “lords-and-ladies” and other gender-related names refer to the plant’s likeness to male and female genitalia symbolising copulation
The leaves of A. maculatum appear in the spring (April–May) followed by the flowers borne on a poker-shaped inflorescence called a spadix, which 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. The leaves may be either purple-spotted (var. maculatum) or unspotted (var. immaculatum).
