TREES IN SCOTLAND 173 



Botanic Gardens, which are much exposed to cold 

 winds, I feel fairly certain I could grow them here, 

 where I can give them more protection. 



Rhodotypus kerrioides. A very pretty hardy shrub, 

 flowering on and off all the summer. It has very 

 clean white flowers, and from appearances looks as 

 though a cross with Kerria might be successful. The

 in flower or foliage, and the latter turns to a good 

 colour in autumn. 



Ribes. No garden should be without a plant of 

 the Common Ribes. I also grow Aureum and a pale

 garden sense) are the Penzance Briars, Rosa rugosa 

 (Japanese Rose), Austrian Briars, R. spinosissima, 

 Blairii II., Charles Lawson, R. macranlha, R. alpina,

 young ones are breaking vigorously. 



Rubus deliciosus. Very pretty white flowers, large 

 for a bramble. It appears to be quite hardy, but is 

 not a very strong grower. 



Ruscus aculeatus (Butcher's Broom). An incon-
