Kelway's Magnificent New Tree Pæonies for 1902-3.
The set for Twelve Guineas. Marvellous Introductions.
Simple statements as to the colour and size of flowers give no idea of their actual living beauty. This is particularly true when such plants as these new varieties of Tree Pæonies are in question. They certainly BEGGAR DESCRIPTION. They have immense petals of almost gossamer texture, with sheeny glittering surface and colours of wonderful purity.
Marie Corelli, pretty light rose-colour; semi-double. 21/— each.
