Senna artemisioides is a flowering plant in the family Fabaceae. It is commonly known as silver senna, silver cassia or feathery cassia - although "cassia" generally refers to the largest-growing Cassiinae. Some of its distinct subspecies also have common names of their own.
Senna species are pollinated by a variety of bees, especially large female bees in genera such as Xylocopa.
Sennas have for millennia played a major role in herbalism and folk medicine.
This plant is endemic to Australia, where it is found in all mainland states and territories, except for Victoria.
The species adapts to a wide range of climatic conditions, although it is susceptible to frost, particularly when young. It prefers dry, well drained sites with full sun.
As an ornamental plant, it is propagated readily from seed, which should first be soaked in boiling water. This plant has gained the Royal Horticultural Society's Award of Garden Merit.
