Rhododendron

Rhododendron ponticum

Description:
Rhododendron
Facts:

This was originally brought to the UK in 1763 as an ornamental, it was introduced to many estates as a ground cover plant for game. It creates dense thickets that block the light to other understorey plants, a trait that is made worse by the fact that it is an evergreen. Its leaves are unpalatable to most grazers and insects and its root system creates toxins that prevent other plants competing. Soil acidifier. Commonest on the western side of the UK. Very difficult to remove successfully.
