CLIMBING ROSES AS VINES 265 
these newer kinds have special merit, but the 
older ones are by no means to be forgotten. 
We can now have climbing roses in flower 
continuously from June to October, inclusive. 
There are three distinctly marked groups of 
climbing roses: (1) multiflora, flowering in June; 
(2) setigera, flowering in June; (3) Wichuraiana, 
flowering from July to September. 
The last named has become available only 
since 1893, and some of its more recent hybrids 
promise to extend the season of bloom right up 
to frost. The hybridist has been very active in 
blending varieties of these three groups, so that 
the lines of division are rapidly becoming less 
clearly marked. 
THE MULTIFLORA GROUP 
Without a doubt, the popular Crimson Ram- 
bler, the best known variety of this earliest- 
flowering group, is also the best dark-red-flowered 
climber, and has given a great impetus to pillar 
planting for flower effect. It comes into bloom 
in June, but it is, unfortunately, very liable to 
mildew. Very like it, is Philadelphia, flowering 
about ten days earlier, just when the rose bugs 
are abundant, but it is not so liable to mildew. So 
you may take your choice according to conditions.
