22 THE BOOK OF THE ROSE CHAP, 
or any other Sweet-briars in Rose-beds; for they 
are very strong growers, thoroughly hardy, and 
should not be pruned at all, except to cut out dead 
wood. Their proper place is in a hedge or grown 
. individually in bush form. 
The Ayrshire Rose (R. arvensis).—This too, as 
its name implies, is a native species, found also 
throughout Europe. They have been well called 
running Roses, for the growth is extremely long, 
rapid, and slender. Being very hardy and ready to 
orow anywhere, they are better adapted for trailing 
over unsightly places and ugly fences than for actual 
walls, which are best reserved for more valuable and 
tender sorts. This and the next group also form 
good weeping Roses, budded on a tall standard, as 
the shoots are very pliable, and trail gracefully 
downwards in a natural manner. 
Several of the Ayrshires have probably been 
slightly hybridised, a mark of the true sorts being 
that the flowers are not borne in clusters. Dundee 
Rambler, Ruga, and Splendens or Myrrh-scented 
are among the best known. The flowers are small, 
semi-double, and mostly white or pink. The plants 
are quite hardy, very rampant in growth, and most 
effective when allowed to ramble at will, unpruned 
and untrained. 
The Evergreen Rose (R. sempervirens).—This group 
is very much like the last, but is not a native of Great 
Britain; nor is it, strictly speaking, evergreen, but 
some foliage is generally retained through most of 
the winter. The flowers are produced in very large 
clusters, mostly of white or light pink colours. The 
plants are thoroughly hardy, as strong in growth as 
the Ayrshire, and useful for pillars, arches, weeping
