About this species
Euphorbia stricta is an annual herb with a milky latex, widespread throughout Europe but uncommon in the UK except in a small area around Gloucester. Because of this it is sometimes known as Tintern spurge. It may also be found listed under the name Euphorbia serrulata. The plant is cultivated only occasionally, but spreads rapidly.
