Senna phyllodinea, commonly known as Silver Cassia, is a perennial shrub native to the arid inland regions of Australia, including western New South Wales, Queensland, South Australia, and the Northern Territory. It is adapted to dry, open woodlands and scrublands where it can reach up to 5 feet in height. This bushy shrub is characterized by its silvery-green, pinnate leaves and bright yellow flowers, which are arranged in racemes and bloom throughout the year, providing a long-lasting display of color.

Silver Cassia is valued for its drought tolerance and ability to thrive in a variety of soils, making it a suitable choice for xeriscaping and low-water gardens. It is often used in cultivation for habitat restoration projects and as an ornamental plant in arid landscape designs. In cultivation, it requires minimal water once established, prefers well-drained soils, and can tolerate full sun to partial shade. While it is generally low-maintenance, it may be susceptible to root rot in poorly drained soils.CC BY-SA 4.0
