"Roses and the frost at Stamford" by Charles Laxton
During the nights of the 1st, 2nd, 3rd, and 4th of January my thermometer registered here, in a walled garden at five feet from the ground, and in the open, 23°, 21°, 22°, and 22° of frost respectively... The snow here froze on the branches, and was three inches deep on the ground.... My list of uninjured (No. 1) may therefore be relied upon as containing only thoroughly hardy sorts.

The Hybrid Perpetual Rose. (Rosier Hybride Remontante.)
Carmine and Cherry-coloured.
The Duke of Cambridge, Lord Palmerston, Le Ville de St. Denis, Madame Heraud, Madame Furtado- a perfect pattern of elegance in shape- and Madame Charles Crapelet, are the 'crème de la crème' of this group, and no roses can be more charming; they all, or nearly all, have an intensity of rose colour, if the expression may be used, which is of all colours the most pleasing; for do we not say ' the rosy morn,' the rosy hues of life, and employ many other expressions, all denoting the invariable charm of this most delightful of all tints?
