Summary
Senna corymbosa, commonly known as Argentine Senna, is an evergreen shrub native to Argentina, Brazil, and Uruguay, where it thrives in open woodlands and scrub areas. It typically grows to a height and width of 3-5 feet (0.9-1.5 meters), forming a dense, rounded shape. The plant is adorned with bright yellow flowers from late summer to fall, which are highly attractive to pollinators such as bees and butterflies. The foliage is pinnate with small leaflets, and the plant may produce seed pods after flowering.
Argentine Senna is valued for its showy flowers and ability to attract wildlife. It is used in gardens for border planting, as a specimen shrub, or in pollinator gardens. It is relatively easy to maintain, requiring full sun and well-drained soils with a preference for loamy and peaty substrates. While it is frost-hardy to some extent, it benefits from protection in colder climates. Propagation is commonly done through cuttings in warm, protected conditions. Gardeners should be aware that Senna corymbosa can become invasive outside its native range, so it is important to check local regulations before planting.CC BY-SA 4.0
