Billy Boiler. Modern. Large flowered climber. Medium red. Repeat-flowering. This variety is a fairly vigorous climbing rose of a brilliant red color but with only 10 or 12 petals that are of good substance. Its color and strong fragrance are its chief assets. ‘Billy Boiler’ grows to 10 ft (3m) in height and has attractive foliage, although it can suffer from mildew in autumn. Eye catching in spring, it makes a good pillar rose and there is some repeat bloom, mainly in late autumn. It can also be used on a tripod or to cover a fence. Zones 5-9. Clark, Australia, 1927. ‘Oskar Kordell’ [sic] x unknown.
