Summary
Senna sulfurea, commonly known as Sulphur Senna, is a perennial shrub native to the Indian subcontinent. It can grow up to 2-3 meters tall and equally wide, with a rounded form. Sulphur Senna is recognized for its bright yellow, butterfly-attracting flowers that bloom throughout the year, particularly in warmer climates. The plant’s foliage is also noteworthy, with pinnate leaves that are green to gray-green in color.
Sulphur Senna is valued for its drought tolerance and continuous flowering, making it a popular choice for tropical and subtropical landscapes. It is often used for hedging, ornamental displays, and as a specimen plant. In cultivation, it thrives in full sun and requires well-drained soils. While it is adaptable to a range of soil types, it performs best in soils that are moderately fertile. Regular pruning can help maintain its shape and promote denser foliage. Sulphur Senna is generally pest-resistant but can be susceptible to root rot if overwatered or planted in poorly drained soils. It should be monitored to ensure it does not become a problem.CC BY-SA 4.0
