About
Spartium junceum, known as Spanish broom, rush broom, or weaver's broom, it is a species of flowering plant in the family Fabaceae and the sole species in the genus Spartium. It is closely related to the other brooms (in the genera Cytisus and Genista).
Safety
Few cases have been described of intoxication by the S. junceum, including accidental ingestion of different parts of the plant by children. The alkaloids found in all parts of the plant have toxic effects. They initially provoke a transitory stimulation of nicotinic cholinergic receptors followed by a persistent inhibition caused by desensitization. The sparteine has an effect on the heart, reducing its sensitivity and conductivity.
Symptoms present depending on dose, method of exposure, and time elapsed since exposure; these include irritation of the oral and pharyngeal mucosa, hypersalivation, vomiting, stomach pain and diarrhea. In severe cases, neurological symptoms (such as midriasis, headaches, delirium and convulsions) may be present, as well as hypotension, bradycardia, and coma.
Where it grows
This species is native to the Mediterranean in southern Europe, southwest Asia and northwest Africa, where it is found in sunny sites, usually on dry, sandy soils.
Uses
The plant is used as an ornamental plant in gardens and in landscape plantings. It has gained the Royal Horticultural Society's Award of Garden Merit.
