I think my soil is fairly acid, David. I would have got my plant from work a long time ago. It is easy to propagate. Just pull a bit off and stick it in the ground. It is time it was reduced in size. This one or one similar can be seen as a cottage garden plant in this area, passed from neighbour to neighbour and nobody knows its name. I have seen it growing well at Ballindalloch Castle and at Tilliepronie, both inland gardens which would get very cold in winter.
