Hybrid Perpetual Roses.
Charles Darwin
A meritorious variety chiefly noted for its rather unusual colors- a brownish crimson with a shade of violet, the deepness of the tones depending upon the angle from which the flowers are observed. This variety was originated in England in 1879, and is from Madame Jule Duran, a popular French Rose. The plant is semi-dwarf in habit, yet is a free grower and produces a multitude of very beautiful and distinct flowers. The plant is reasonably hardy, but needs a little more attention than some of the better-known Hybrid Perpetuals- but the inherent loveliness of the large blossoms compensates one for any effort bestowed in the cultivation of this Rose.

Hybrid Perpetuals
Charles Darwin (Laxton, 1879). — Good growth and foliage, the blooms having a colour described universally as brownish-crimson. I have been unable to detect the brown shade, but must, as I have said, leave these delicate distinctions of tints to experts. Rather late, and a good autumnal. The shape is open, and the variety does not prove very satisfactory with me, though often well shown by others.
