"Forgotten Roses."
It is not surprising that owing to the numerous new Roses many of the excellent older sorts have been crowded out. Beautiful as the Hybrid Teas unquestionably are, I think it will be a bad day for lovers of the Rose if they allow this group to drive out of cultivation many old and well-tried varieties of other classes that are too good to suffer extinction. I often wish there were a National Rose Garden, where every variety could be planted, so that rosarians could see for themselves the true value of each. How some of our much-praised Roses would have to give place to those less known but better, at least in the matter of "doing well" and in point of colour.
I append a list of a few varieties that are comparatively unknown, yet I can recommend every one with the full assurance that they would please the majority of the readers of The Garden. Among what are regarded as climbing Roses not one of the Rambler race can surpass.
Mosella.—One of a small group known as Hybrid Polyanthas- rather a misnomer, seeing that all are hybrids-but practically this Rose is nearer the Teas.

This is everybody's Rose. Fully as hardy and equally as free blooming as Clotilde Soupert or Pink Soupert; like them a strong, dwarf, bushy grower, specially adapted to pot culture. Flowers produced in clusters, and of the same Camellia-like form as Clotilde Soupert. The color is white on beautiful light yellow ground, which becomes a chrome yellow in the centre of flower. If you want a genuinely satisfactory Rose, take our advice and try this variety.
