Euphorbia amygdaloides robbiae is a softly hairy, evergreen perennial with a bushy habit. Its reddish green stems bear spoon shaped to obovate, shiny, leathery leaves which are up to 6cm long. In early spring and early summer it bears terminal cymes of greenish yellow cyathia and involucres. This plant spreads by means of underground root runners.

Euphorbia amygdaloides  robbiae, commonly known as Wood Spurge and the variety robbiae is also known as Mrs Robb’s Bonnet. The species Euphorbia amygdaloides is found throughout Europe in moist woodland habitats.

Euphorbia is named after Euphorbus, physician to Juba, a king of Mauritania. Amygdaloides is derived from the Greek amugdalos ‘an almond tree’ and oeidhs ‘egg shaped’. Robbiae is named for the plant hunter who discovered it, Mary-Anne Robb, with its common name coming from how she had to smuggle it through customs, in her hat.
