ScotsPine_Bonsai_Tree_Winners.jpg image INDIGENOUS TREES (SCOTLAND) - The least difficult of trees to grow are indigenous trees i.e. those that grow naturally around us in the countryside and are used to our climatic fluctuations.

A great example is Pine - Scots (Pinus sylvestris) which is a super but often overlooked tree for BONSAI>BONSAI since it grows predominantly in the north of the UK i.e. Scotland. Another example is FIELD MAPLE (ACER CAMPESTRE) which although widespread in Southern England is predominantly found as bushes and only in the South of Scotland.

The attached web link leads to a web site by the Scottish Government which outlines most of Scottish indigenous trees.
