[From "The Story of Harry Tevis, Rose Lover", by Darrell g.h. Schramm, pp. 16-22]
The rose named for the countess, ‘Comtesse Festetics Hamilton’, is a tea with color ranging from carmine red to pale pink with coppery reflexed petals in the center; bred by Nabonnand, it was introduced in 1897. A tall, wide bush, ‘Comtesse Festetics Hamilton’ is still available from a few rose nurseries.

[The attribution of the rose to American heiress Eila Haggin, who married Count Rodolphe Festetics de Tolna in 1892 is incorrect - see Note.]

Another fine red is Comtesse Festetics Hamilton, its flowers are a coppery carmine of pretty shape, and fine in the autumn. Strangely, many of these glorious teas came to us from the sunny Riviera, and I should not be surprised to see more of them, for they seed abundantly. Even from promiscuously sown seed glorious varieties are produced. Amateurs who have friends living out there should beg some of the well-ripened seed pods and sow them in pots, in a sandy compost, and placed in a warm greenhouse. They would obtain some delightful varieties, perhaps even surpassing those already in commerce. The little seedlings should be potted on into tiny pots known as "thimbles" when they show their third leaf and grown on unchecked, and re-potted as required. If these little plants are planted outdoors in June or July, they make fine plants by the fall. It would be necessary to pot them up again for the winter. Any promising kind could be budded in due course, and many of our best bedding Roses have been raised on similar lines.
