Actaea simplex, commonly known as baneberry or bugbane, is a clump-forming rhizomatous herbaceous perennial native to moist woodland edges, forest clearings, and shaded riverbanks in Eastern Asia. It typically grows to 1.2 meters (3.9 ft) tall by 0.6 meters (2.0 ft) wide, featuring trifoliate and pinnate basal leaves. From late summer to early fall, it produces erect or arching stems with short terminal racemes of fragrant white flowers that are particularly showy and attract pollinators. The foliage can add texture to garden settings, and the plant is valued for its late-season blooms.

Actaea simplex thrives in part shade to full shade, preferring medium-moisture, well-drained soils rich in organic matter. It is suitable for hardiness zones 4 to 8 in the US. The plant is often used in woodland gardens, shaded borders, and naturalized areas. It requires consistent moisture and should not be allowed to dry out, especially in hot, sunny conditions. While it is generally low maintenance, it can be susceptible to leaf spot and snail or slug damage. Gardeners should handle this plant with care, as all parts are highly toxic if ingested.CC BY-SA 4.0
