TREES IN SCOTLAND 167 



foliage is seen to the best advantage, but it is quite 

 hardy and looks well climbing into a thin tree such 

 as the Common Almond. 



Berberis (Mahonid) Aquifolium. A handsome plant at 

 all times, and will even grow under the shade of trees. 



Berberis Darwinii. Very bright in flower. Young 

 and sappy shoots get killed back in winter. 



Berberis Thunbergi. A most attractive Berberis ; 

 it makes a small neat-growing bush to which the 

 adjective " sparkling " might be applied. Its chief 

 glory is its autumnal foliage, and a large clump in 

 September is " a sight to, see " ; quite hardy. 



Berberis vulgaris. Very beautiful when clustered 

 with fruit. The purple-leaved variety (B. v. purpurea) 

 is most useful for its foliage. 



Betula alba purpurea. A good foliage tree. 



Buddleia globosa. This does well in a warm 

 sheltered spot facing south-west, where the morning 

 sun in winter will not touch it too soon. It also 

 objects to exposure to cold winds. 



Calycanthus floridus. Quite hardy, and grows well 

 in half-shady places. 



Ceanothus azureus. This succeeds either trained to 

 a wall or as a bush. In the latter case it should be 

 in a sheltered position. It seems quite frost-proof, 

 and its blue flowers are very beautiful at a time 

 when few shrubs are in bloom (July and August). 

 Its shoots should be well thinned, and those left 

 shortened as soon as the buds begin to show signs 

 of movement in the spring. The best form I have 

 tried is Gloire de Versailles.
