Summary

Senna roemeriana, commonly known as Twoleaf Senna, is a deciduous perennial herb native to Texas and northern Mexico, where it thrives in open grasslands, prairies, and desert scrub environments. It typically grows to a height of 1-2 feet (0.3-0.6 meters) and a width of 2-5 feet (0.6-1.5 meters), often forming a rounded shape. The plant features compound leaves with two leaflets and bears bright yellow, pea-like flowers from late spring to early fall, which are moderately showy and attract pollinators.

Twoleaf Senna is valued for its drought tolerance and ability to adapt to poor soils, making it a suitable choice for xeriscaping and naturalized areas. It is often used in rock gardens, as a ground cover, or in borders for its low maintenance and attractive foliage. This plant prefers full sun to part shade and requires well-drained soils. While generally pest-free, it can occasionally suffer from root rot if overwatered. Twoleaf Senna is also recognized for its potential medicinal properties, although it should be used with caution as some parts can be toxic if ingested.CC BY-SA 4.0
