Cytisus scoparius |
Common Broom (Cytisus scoparius or Sarothamnus scoparius), also known as European Broom, Scots Broom*, Irish Broom or English Broom is a perennial, leguminous shrub native to northwestern Europe, where it is found in sunny sites, usually on dry, sandy soils. It has been widely introduced into other continents, and is regarded as a noxious invasive species in many places such as California and New Zealand.
Like most brooms, it has green stems with small deciduous trifoliate leaves, and in spring and summer are covered in profuse golden-yellow flowers. In late summer, its pea-pod like seed capsules burst open, often with an audible crack, spreading seed from the parent plant. It makes a shrub about 1-3 m tall, rarely to 4 m. It is also the hardiest broom, tolerating temperatures down to about -25°C.
