Also called Feathery senna, Wormwood senna, Burnt-leaved Acacia, Desert Acacia, Grey Acacia, Limestone Acacia, Punty Acacia
Silver senna is a drought-tolerant Australian shrub with feathery grey-green foliage and yellow flowers, mostly in winter. The key to growing it is full sun and very well-drained soil, with protection from frost while young.
Senna artemisioides, commonly known as silver cassia, is a species of flowering plant in the family Fabaceae and is endemic to Australia, where it is found in all mainland states and territories. It is a shrub with pinnate leaves, the leaflets variable, yellow flowers mostly occurring in winter, and linear pods. Six subspecies, four hybrid subspecies and two subspecies named but not yet described are accepted by the Australian Plant Census.
Senna artemisioides adapts to a wide range of climatic conditions, but is susceptible to frost, especially 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 briefly immersed in boiling water.
This species has gained the Royal Horticultural Society's Award of Garden Merit.
Silver cassia is endemic to Australia, occurring in all mainland states and territories, and has been introduced to California, the Canary Islands, Cyprus, India, Iraq, Spain and Zimbabwe.
