blairs...think you mean Rhododendron ponticum.
On no account plant this ....it is an invasive shrub .
It costs the country millions trying to irradicate it.
It smothers all our native wild flowers.

Suckering of the root, together with its abundant seed production, has led to it becoming an invasive species over much of western Europe and in parts of New Zealand. Rhododendron control, or "rhodie-bashing", is a key element in nature conservation in those areas.3] Conservation organisations in Britain now believe R. ponticum has become "a severe problem" in the native Atlantic oakwoods of the west highlands of Scotland and in Wales, and on heathlands in southern England, crowding out the native flora.4] Clearance strategies have been developed, including the flailing and cutting down of plants with follow-up herbicide spraying. Injection of herbicide into individual plants has been found to be more precise and effective.5]
