- Origin and Distribution:
- The species is native to both Europe and Asia. It is believed that the current populations of Rhododendron in Ireland have been introduced from material taken from both the Iberian Peninsula populations and the Asian populations of this species. Rhododendron has a complex history.
- Rhododendron can form very dense thickets and out-compete native plants for space and resources, especially for sunlight. Other impacts on fish and invertebrate communities have been recorded. Rhododendron can also prevent access to sites by the shear mass of plant material blocking paths and right of way.
- How did it get here?
- Natural dispersal by seed and vegetative means and garden escapees planted by people.
- Is it found in Ireland or Northern Ireland?
- Planted in gardens, parks and demesnes across Ireland and Northern Ireland.More information can be found at NBDC and NBN Atlas NI.
