Euphorbia hyssopifolia, commonly known as Hyssopleaf Sandmat or Hyssopleaf Spurge, is a slender annual herb native to the tropical and subtropical Americas, including the southern United States. It is characterized by its erect to sprawling growth habit, typically reaching 10 to 30 inches in height with arching stems that can be green, pinkish, or reddish. Frequently found in disturbed areas like garden beds, roadsides, and sandy washes, the plant emits a toxic, milky white latex if damaged and produces three-lobed capsules containing small, blackish, wrinkled seeds.
