'''''Senna artemisioides''''' is a [[flowering plant]] in the [[family (biology)|family]] [[Fabaceae]]. It is commonly known as '''Silver Cassia'''<ref>http://plantnet.rbgsyd.nsw.gov.au/cgi-bin/NSWfl.pl?page=nswfl&lvl=sp&name=Senna~artemisioides</ref> or '''Feathery Cassia'''<ref>http://cals.arizona.edu/pima/gardening/aridplants/Cassia_artemisioides.html</ref> - although "cassia" generally refers to the largest-growing [[Cassiinae]]. Some of its distinct [[subspecies]] also have common names of their own. This is a shrub that grows up to 3 metres in height. It has pinnate leaves with between 1 and 8 pairs of leaflets. It produces an abundance of yellow flowers in winter and spring which are about 1.5 cm in diameter, followed by 2 to 7 cm long flat green pods which age to dark brown. 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.<ref>http://asgap.org.au/s-art.html|title=''Senna artemisoides''</ref> ==Cultivation== ===Propagation=== ===Pests and diseases=== ==Varieties== The species was first described and placed in ''[[Cassia (genus)|Cassia]]'', but nowadays it has been moved to ''[[Senna (genus)|Senna]]''. However, for a long time this plant was erroneously known as ''[[Cassia eremophila]]'' which is a true species of ''Cassia'' called [[Desert Cassia]], described by [[Julius Rudolph Theodor Vogel]]{{wp}}. A large number of formerly independent species are provisionally considered [[subspecies]] of ''S. artemisioides''{{wp}}: * ssp. ''alicia'' <small>Randell</small> * ssp. ''artemisioides'' * ssp.
