The Autumnal Roses.
The Bourbon Roses are real "perpetuals" or "remontants" rather, blooming more or less freely from frost to frost again. They are less thorny than either [the Hybrid Perpetuals or Damask Perpetuals], the thorns being strong and usually light-colored. The leaves are firm, almost leathery, smooth and glossy. The petals or flower-leaves are also unusually thick, and with a peculiar satin-like or burnished appearance that adds much to their beauty, and enables them to endure the heat of a summer's sun hot enough to cause all others to flag. The growth is hardy and luxuriant.
24. Souchet—crimson shaded with purple; large and very double; habit, rather dwarf and compact. 
Bourbon roses require but little pruning. Towards the end of February, their shoots may be thinned, and the long ones shortened.

Les Massifs de Rosiers.
..nous avons indiqué comment on pouvait obtenir de beaux massifs de rosiers de la section des hybrides; nous entreprenons aujourd'hui d'en former avec les rosiers dits de l'Ile Bourbon. Nous avons choisi, comme pour les hybrides, les variétés dont la végétation, à peu près égale, permet de les planter dans un même compartiment de parterre, et nous continuons de marquer par le signe + celles d'une végétation un peu plus grande et par celui de — les variétés qui poussent modérément.
— Souchet, carmin pourpre.
