The Craigends Yew, Renfrewshire
The Craigends Yew is one of the largest and possibly oldest examples of a layering yew (Taxus baccata) in Scotland. These are yews which have chosen to lay down their branches as they grow, which then root and send up new stems. Eventually, as the central stem dies back, these can become remnants of the original tree, with identical DNA.
The tree can be found close to a housing estate by the river Gryffe in Houston.
