Royal Scarlet Hybrid Climber
Chaplin 1926
Resembles Paul's Scarlet Climber, but the colour is deeper and more vivid dark red. Very large, semi-double flowers in large clusters. Moderate growth with stems up to 6-9 ft. Both these climbers are difficult from the viewpoint of colour, when used in large numbers or when planted against a red brick wall.

Wichuraiana and other Rambling Roses
The varieties comprising these classes are of unique and charming beauty, and form lovely objects in the garden while in bloom. They are suitable for rockery, sloping banks, pillars, pergolas, arches, etc. They are very lovely grown as standards.
Royal Scarlet... Similar to "Paul's Scarlet Climber", but of a deeper shade of colour. Flowers not quite so large as "Paul's Scarlet". This should prove an acquisition to the climbing varieties. Introduced 1926.
