Gorse Ulex spp
Three species of Gorse that exist in the UK are Ulex europaeus, Ulex gallii and Ulex minor:
Ulex europaeus is also known as Western gorse, Furse, and Whin (originally thought to be a Scandinavian word). Other names for this type of Gorse are Fingers-and-thumbs, French-fuzz and Honey-bottle.
Ulex galii, commonly known as Dwarf furze, is also called Bed-furze, Cat-whin and Cornish fuzz. This species belong more to the west and to Ireland and will not tolerate lime in the soil.
Ulex minor belongs more to the south-eastern counties, East Anglia and the home counties. 
The stunted plant is dense and has lots of branches. It is evergreen, but the leaves are very minute and fall off early, not being present in the older stages when they take the form of long, thread-like spines, which are straight and furrowed, or branching. The stem is hairy and spreading. The golden-yellow flowers have a distinctive coconut-scented perfume, filling the air.A spiny evergreen shrub with yellow flowers.
Few plants make such an impact on the landscape as flowering gorse, through both its colour and scent. The latter is a distinctive coconut and vanilla smell, said to be quite pungent to some individuals, but weak to others

Don’t overeat! The plant contains slightly toxic alkaloids.  AVOID WITH HEART ISSUES AND HIGH BLOOD PRESSURE.
Ulexine, found in the seeds, is one of a group of isoflavonoid alkaloids that are sodium channel blocking antiarrythmic agents. They can relieve cardiac oedema, but they also increase blood pressure. These actions are thought to be the cause of the toxic effects that occur upon accidental ingestion of parts of broom and lupin plants. They are not approved for use in humans as antiarrythmic agents.
