Broom ???

Good old google .I questioned why such a stunning bush of yellow flowers  should be labeled with such an innocuous name .
Broom is a large, deciduous shrub, similar in appearance to Gorse, but without the spines. This member of the pea family is common on heaths, in open woodlands and along hedgerows and can be found at the coast. Its bright yellow flowers appear in spring, from April to June, and smell of vanilla. It is quite likely that Broom got its name from the fact that its long, whip-like stems were cut and tied together to make brushes. Although a number of similar species were also used in this way, Broom created the best brooms!
