Fabaceae - Cytisus scoparius

What does it look like?

Broom is an upright, many-branched, almost leafless woody shrub, up to 3m tall.  It is a perennial plant, with a stout taproot.  Leaves are sparse, mostly narrow and simple.  It has golden-yellow flowers in spring that are 2.5cm long, and produces seed pods in summer which are black when ripe and explode loudly on warm days, scattering the seed.

Broom grows in river beds, hedgerows, low-fertility hill country, scrubland, coastal and disturbed land.  It is tolerant of a wide range of conditions including drought and frost, but requires good drainage. 

Why is it a problem?

Broom is an aggressive invasive shrub that seeds prolifically, with each pod producing nine seeds and usually more than 2000 pods/bush.  Broom forms a substantial seedbank and the seeds can still be viable after five years.

Control Methods
