Not enough attention is given to the Tea Roses and Bourbons. The Hybrid Remontants justly claim our first attention when they are in their perfection; but after their first blooming is over, throughout July, August, and September, they are much less attractive than many monthly Roses. Varieties like Bougère, Gerard Desbois, Homer, Sombreuil, Madame de Vatry, Marie Van Houtte, Madame Caroline Kuster, will give a continuous supply of flowers throughout the summer and autumn.

Homer, Madame de Vatry, Marie Ducher, Sombreuil.

"The Best Twenty-four Monthly Roses for Bedding."
By H. B. Ellwanger, Rochester, N. Y.
The requisites for a good bedding rose are freedom of bloom, healthy habit of growth, good form, pure, steadfast color, fragrance, and sufficient fulness of flower.
The following varieties are, in my opinion, the best for the purpose:
