T. W. Girdlestone in The Garden, U.K. 
Lady Castlereagh (Dickson). - As far as has been at present seen this is the best tea-scented rose of the year. The plant is a vigorous grower, the foliage handsome, the flowers large, finely formed, and of a pleasing shade of rosy yellow, with rose-color predominating at the margins of the petals, which being of great substance ensure the satisfactory expansion of the bloom, while it is very free-flowering and a thorough autumnal.
