Spurge - Euphorbia esula
Family: Euphorbiaceae
Description
This is a knee-high perennial herb that grows back each year from roots. These roots can be up to 20 feet deep and thus make irradiation efforts difficult. It has small leaves along its stalk. On top of the stalk are yellow-green heart-shaped bracts that each enclose a small flower. Upon maturation of the seed capsules are spring-loaded and able to throw seeds up to 15 feet.
Interesting facts
Like other euphorbs, this plant contains a milky sap that can cause blisters or dermatitis if it contacts the skin. Thus, protection should be worn when handling these plants.
Several insects have been used for biocontrol including a stem/root boring beetle, a shoot-tip gall midge, a stem-boring moth, and three root defoliating flea beetles. These insects have however, not proven them selves reliable in the field and more efforts are needed to control this plant.
