This group was the only repeat-blooming one known to the Europeans
until the advent of the China roses. It had indeed been known seemingly
in at least one variety ('Bifera') since Roman times. Another cultivar
('Tous-les-Mois') appeared in the 17th century, and breeding work in
earnest began on them in the 1810's. Vibert and his successors in his
firm had a very great interest in this group, and introduced by far the
greatest number of them, the last one ('Rembrandt') of their
long-pursued line coming out in 1883. They typically have stocky,
healthy, decorative bushes, with the often exquisitely double, fragrant
blossoms nestling in the leaves. There are several races of them: the
Biferas, with tall, arching growth; the Portlands, showing Gallica
influence; the Tous-les-Mois, the typical sort, bushy and compact with
tight blossoms; and the Trianons, tall, vigorous, Hybrid-Perpetual like
growth with clusters of flowers. The colors range from white through
all the pinks to deepest red. 'Jacques Cartier', `Yolande d'Aragon',
`Portland Rose', `Rose du Roi', `Joasine Hanet', `Marbree'.
