Plant in full sun and well-drained soils. Irrigate only occasionally to infrequently as overwatering makes plants leggy. Hardy to around 20° F and useful in USDA Zone 9 and above. It is drought tolerant and handles wind, high heat and reflected heat exposures. It is a great showy and adaptable plant for a hot dry location that is attractive in or out of flower and the flowers are attractive to bees and butterflies.

Senna phyllodinea is native to dry inland plains on rocky soils, often in large colonies, in Queensland, New South Wales South Australia and New Territories. This species was long been included with the genus Cassia that Linnaeus authored in 1753 but was more closely allied with the plants in the genus Senna, a genus described by Phillip Miller only a year later; most recent treatment has moved it to Senna but Cassia and Senna are a monophyletic group (a clade) and further work on them may just as well combine them again in the future. The name for the genus comes from Arabic 'san' or 'sany' that was used for a thorn-bush and a herbal used by the Arabian physicians. The specific epithet means leaves without pinnae in reference to the leaves being reduced to a flattened enlarged petiole, called a phyllode. It is also commonly called Silver Cassia or Silvery Cassia. It is somewhat similar and confused in the nursery trade with the more common Senna artemisioides.
