PLANT BREEDING IN CANADA by W. T. MACOUN
Two worthy varieties of roses originated at Ottawa by the late Dr. Wm. Saunders are Mary Arnott and Agnes, the former a brilliant crimson scarlet cross between Rosa rugosa and Prince Camille de Rohan, the latter, pale yellow with a salmon tinge, a cross between Rosa rugosa and Persian Yellow.

The second cross, that is to say, the Tea rose x R. gigantea, produced several very excellent and beautiful hybrids, chiefly characterized by their soft coloring, their great profusion of blooms, and their greater resistance to cold. Among these we may especially note:
1st. Amateur Lopes, from Mme. Bérard x R. gigantea. Flower very large and full, pale salmon, washed with rose-lilac at the tips of the petals. A very floriferous plant of average vigor.

2nd. Belle Portugaise, from Souvenir de Leonie Viennot x R. gigantea. A large and beautiful rose of very delicate coloring—shell pink touched with salmon. The very long buds reach a length, sometimes, of 10 cm. (4 inches), especially when they are produced at the ends of vigorous branches. The flower, when completely open, may measure from 15 to 16 centimeters (6-6.5 inches) in diameter. Grown in a temperate climate, Belle Portugaise attains a great development and is literally covered with its large blooms. It seems to have inherited the great luxuriance possessed by the mother plant, Souvenir de Leonie Viennot; moreover, it is able to produce fertile seeds, and might thus be very usefully employed in hybridization.

3rd. Dona Palmira Feijao, from Souvenir de Leonie Viennot x R. gigantea. Flower large, very full, shell pink in the center, the outside of the petals bright carmine. Very brilliant coloring.

["Rosa Gigantea And Its Hybrids" by H. Cayeaux]
Although the first flowering of R. gigantea took place in 1896, I did not begin the hybridizations until 1898, when I obtained some seeds which, planted in 1899, produced plants whose first flowers did not appear until 1903, four years later. I confess that this period of four years of waiting seemed to be very long; but there is nothing surprising about it if one considers that the seedlings produced by R. gigantea are so vigorous that they must reach a considerable development before deciding to bloom. It was from this series that I had the satisfaction of seeing the beautiful Etoile de Portugal appear, which performs wonders when cultivated in a climate where orange trees grow....

Descending from the first cross, the variety Etoile de Portugal is the produce of Rosa gigantea x Reine Marie-Henriette. This plant bloomed for the first time in the Botanical Gardens of Lisbon in 1903. It is of luxuriant growth and seems to have inherited from Reine Marie-Henriette its great abundance of flowers. The elongated buds are often borne by twos or threes on the same flower stalk. The blossom is large, full and fragrant, of a lustrous carmine rose color, shaded to yellow at the base of the petals, which become a lighter color when in full bloom. It should be grown in a temperate climate if one wishes the plant to reach its maximum development and produce in abundance its masses of flowers, of such brilliant and delicate coloring.

Rosa Gigantea And Its Hybrids by H. Cayeux
Henri Cayeux describes how Rosa gigantea bloomed in Europe for the first time in April 1896 in the Lisbon Botanical Garden. Cayeux recommends grafting a flowering branch to Rosa indica to obtain flowering much earlier than from plants grown from seed, which grow so vigorously, up to 8 to 10 meters a year, that they flower very little. He also reports even more generous bloom by top grafting Rosa gigantea on Tea roses that have been grafted on Eglantine, thus allowing hybridizing without using a ladder.
