Also known as Outback Cassia. Many people have remarked that the coloration of this attractive shrub is similar to the high elevation native manzanita. Outback Senna, an Australian native, has glossy green leaves and red stems. It grows to about 5 feet tall and wide, with a naturally rounded form. In the springtime it is covered with yellow flowers, followed by decorative reddish-bronze seedpods. Outback Senna should be planted in full sun and well-drained soil. It doesn’t appear to be acclimated to cool, moist climates, but loves our hot dry heat. It is cold hardy to the low 20’s F. USDA Zone 9.
