Spartium
''Spartium junceum'', commonly known as Spanish broom or weaver's broom, is a species of flowering plant in the family Fabaceae, native to the Mediterranean in southern Europe, southwest Asia and northwest Africa,〔(GRIN Species Profile )〕 where it is found in sunny sites, usually on dry, sandy soils. It is the sole species in the genus ''Spartium'', but is closely related to the other brooms in the genera ''Cytisus'' and ''Genista''. There are many binomials in ''Spartium'' that are of dubious validity (see below).
The Latin specific epithet ''junceum'' means "rush-like", referring to the shoots, which show a passing resemblance to those of the rush genus ''Juncus''.
==Description==
''S. junceum'' is a vigorous, deciduous shrub growing to tall, rarely , with main stems up to thick, rarely . It has thick, somewhat succulent grey-green rush-like shoots with very sparse small deciduous leaves 1 to 3 cm long and up to 4 mm broad. The leaves are of little importance to the plant, with much of the photosynthesis occurring in the green shoots (a water-conserving strategy in its dry climate). The leaves fall away early.〔(Jepson Manual Treatment )〕 In late spring and summer shoots are covered in profuse fragrant yellow pea-like flowers 1 to 2 cm across. In late summer, the legumes (seed pods) mature black and reach long. They burst open, often with an audible crack, spreading seed from the parent plant.
