The Bourbon Rose. (Rosa Bourboniana.) Rosier de L'Ile Bourbon.
There are a few Bourbon Roses, of remarkably vigorous habits, scarcely adapted for planting in beds, as all those above described are,—such are Apolline, of a beautiful and glossy rose colour; Louise Odier, almost equal to Coupe d'Hebé in the shape of its bright rose-coloured flowers; Paxton, a vigorous grower, with flowers of the same colour; Imperatrice Josephine, with light blush flowers; Julie de Fontenelle, Le Grenadier, and Sully, all vigorous-growing crimson roses, and the finest of all for pillar roses. They will require the treatment recommended for summer pillar roses in p.35. For light soils, these Bourbon pillar roses should be budded on the Manetti rose. For deep rich soils they will do very well on their own roots, or budded on dwarf stocks of the Dog Rose.

Stray Thoughts on Roses: Grouping of Bourbon Roses.
If an eligible place in the rose-garden can be found for a group of robust and comparatively tall-growing Bourbons, with pale, flesh-coloured, or nearly white flowers, the following will be found very beautiful: Impératrice Joséphine, Lavinie d'Ost, and Madame Lacharme. These often put forth in July very robust shoots, three to four feet in length; if suffered to grow without being shortened, they produce in August and September a large crowning cluster of flowers; but after the flowers have faded, these long shoots have a bare, straggling appearance; it is therefore an improvement to pinch off the end when the shoot is about one and a half or two feet in length; abundant laterals will then be produced, which will give their flowers in October.
