Rhododendron (Rhododendron ponticum) is a dense, suckering shrub or small tree, that can grow up to 8 metres tall. Although the flowers it produces are stunning, suckering of the root, together with its abundant seed production, has led to it becoming an invasive species over much of Western Europe and is in the top ten most invasive weeds in Ireland where it has spread across heathland, mountains and woodland areas.
How can I identify Rhododendron?
Rhododendron leaves are evergreen, 6-18 cm long and 2-5 cm wide. The flowers, which come in a stunning variety of colours, are 3.5 to 5 cm in diameter, often with small greenish-yellow spots or streaks.
The fruit is a dry capsule 1.5 to 2.5 cm (0.59 to 0.98 in) long, containing numerous small seeds.
How can I get rid of it?
Knotweed NI has carried out Rhododendron clearance on several key sites throughout Ireland for Northern Ireland Water and through wooded areas in large privately-owned estates.
