New Roses 1933.  Corail  (Hyb. Mult.  A. Schwartz 1931) Very vigorous growth, beautiful glossy green foliage. Flower large for the type, pretty form. Colour tender rosy peach, reverse coral rose, shaded carmine. Very good variety for pergola, etc. Price 4/- each.
Flowered within three months of budding, a most unusual occurrence for a climber. Should be an early and continuous bloomer as it flowers on tips and laterals as well.
