1 Claim. 1

This invention relates to a new and distinct variety of hybrid tea rose plant, particularly useful for greenhouse forcing, and differing entirely in both color and growth from any previous rose of which I am aware.

This new rose is distinguished first by its tall upright growth, making very long shoots, all of which matur into flowers, and further showing greater production than the Briarclifi varieties now most commonly used,

The blooms themselves are unique, being characterized by the long pointed form of the buds, slowly unfolding into high centered flowers of novel color, changing from between Begonia Rose and Spinel Pink to between Begonia Rose and Thulite Pink as ageing occurs.

Other features of novelty will more particularly appear in the following detail description of the new rose, the color terminology being in accordance with Ridgways Color Standard:

I claim: A new and distinct variety of rose plant charaoterized as to novelty by its habit of tall up- .right growth'produoing very long shoots all maturing into flowers and having greater production than varieties commonly used for greenhouse forcing purposes, by the shape of its unique flower initiating in long pointed buds which unfold slowly into high centered blooms, and the peculiar color range of the blossom from the full open stage to its finish, substantially as shown and described.
