Messrs. H. Cannell & Sons, Swanley...had a number of cut blooms of Tree Pæonies of much merit. Amongst these were noticeable M. Kleyer, a very fine large rose-coloured flower; Gloria Belgarum, also large and much deeper colour; and Charles Rozier, pure white. Vandermail is the name of another good white variety.
