Arum maculatum is a plant of many common names, among them lords and ladies, cuckoo pint, snakeshead, adder’s root, devils and angels, cows and bulls, adam and eve, naked boy, wake robin, friar’s cowl, jack in the pulpit and wild arum. Many of these names refer to the spadix that looks a little like, ahem, male genitalia.
It is common in woodland areas. The spathe hood varies in colour from pale green to purple, and the leaves range from purple-spotted to plain green.
The flowers are clustered around the base of the spadix, and in autumn form red berries. All parts of the plant are poisonous.
