Cotoneaster (Cotoneaster glaucophyllus)

Also known as: large-leaf cotoneaster

Cotoneaster is a large evergreen shrub. Used as a hedging plant, it now invades bushland and riparian areas.


How does this weed affect you?

Cotoneaster is a significant environmental weed in Victoria, Tasmania and the Australian Capital Territory and moderately in New South Wales. It is commonly found on the fringes of urban bushland and roadsides. It can form thickets under tall trees and can shade out understorey vegetation. 


Cotoneaster is mildly toxic to humans and mild symptoms may occur if large quantities are eaten. The berries are poisonous and in large quantities can cause gastroenteritis.

What does it look like?

Cotoneaster is a large evergreen shrub with leaves that are lighter green - grey underneath. It produces clusters of small, round red berries.
