New Hardy Tea Rose Winter Gem
This is a very beautiful hardy Tea Rose. A perfectly wonderful bloomer, covering itself with lovely buds and flowers the whole year, or as long as it can get a chance to grow, either indoors or out. The blossoms are borne on long graceful stems, fine for cutting, and are large, full and double. The color is an exquisite shade of lovely creamy pink, very distinct and beautiful. It is a strong, rapid grower, and blooms very quickly, even from small plants. It flowers all the time, and particularly in winter, when taken indoors, hence its name, "Winter Gem". But it is good, both summer and winter, and can be depended on for lovely buds and flowers as long as kept in growing condition. It is one of the roses you want, and this whole collection is equally fine and very cheap at the price. Strong plants, 20 cts. each; larger size, 25 cts., postpaid. Two-year size, 50 cts., express.
