sun spurge

Sun spurge, scientifically known as Euphorbia helioscopia, is a type of spurge plant whose flowers turn towards the sun. The term "sunweed" is also used synonymously with sun spurge.12

Spurges belong to the large and diverse genus Euphorbia, which includes at least 2,100 species. These plants exhibit a wide range of forms, from low-growing herbs to shrubs and trees. While some euphorbias resemble cacti, they are distinguished by their milky, often toxic sap. The genus is known for its unique floral structures, featuring a single female flower surrounded by male flowers, all enclosed within a cup-shaped structure called a cyathium. Many spurge species are cultivated as ornamentals, while others are considered agricultural weeds.3
