Upper leaves are roundish, gently tapered toward the stem, and stalked.
All leaves are somewhat crinkled. The greenish yellow flowers are very small, not showy. Fruit are a round, sharply three-angled capsule. Petty spurge prefers moist, shady locations and often occurs among shrubs and flower beds. Broadleaf ID illustration.
