Growing Manuka Trees in Ireland

Can Manuka trees (Leptospermum scoparium) be grown in Ireland or England? Are there specific regions that are more suitable for their growth due to dryer, milder, and less prone to frost and low temperatures? Are there any regulations for growing an alien species like Manuka in Ireland?

Leptospermum scoparium, or Manuka trees, have been present in Ireland for over a century, mainly in mild coastal regions. However, many of these trees have been killed in winter frosts except for those close to the coast. While there are no specific regulations on growing this alien species, it is important to consider the potential impact on the local environment.
