PATENT OFFICE ROSE PLANT Application February 13, 1947, Serial No. 728,339

1 Claim. 1

The present invention relates to a new and distinct variety of hybrid tea rose plant, originated by crossing the variety Charlotte Armstrong (Pl. Pat. #455) with the well-known variety Night (unpatented).

The former of these parents produces blooms of rich cerise color, while those of the pollen parent are deep crimson shaded black to maroon.

This new variety is entirely distinguishable from either of its parents not only as to the colorin of flowers, but is also dominantly distinct and novel from other hybrid tea rose plant varieties in relation to the following characteristics:

(1) An upright-growing plant with greater vigor and floriferousness than other very double roses in its color class substantially as disclosed herein.

(2) Greater length and distinctive form of the bud as compared with other varieties in the petalage and color class of this new variety.

(3) Whereas in most varieties of roses more and larger prickles are found on the main stems than on the branches, this new variety has very few large prickles and relatively few small prickles on the main stems but relatively many small prickles on the branches. This freedom from large prickles on the main stems permits the plants to be more easily handled by both producer and consumer.

(4) Abundant, large, fiat, leathery leaves covering the plant well and adding to its attractiveness.

(5) The leaves are above average for roses of this color range in their resistance to mildew.

A sexual reproduction of this new variety shows the foregoing characteristics come true to form and are established,

The accompanying drawings illustrate specimens of this new variety, showing the flowers in different stages of development from loud to fullopen bloom and the prolific nature of the foliage background for these blooms.

The following is a detailed description of the I new variety, color terminology being in accordance with Robert F.

To summarize the distinctions of this new variety from each of its parents, it is noted that it is distinct from Charlotte Armstrong because of its more upright habit of growth, the more abundant foliage of a darker green color, the leaflets of which are broader in relation to width than those of Charlotte Armstrong; flowers with a deeper shade of red with more petals of a smaller size, particularly in the center of the flower, with an entirely different arrangement of these petals. It differs also in having fewer thorns of both large and small size on the large canes particularly. The form of the buds in this new variety is more ovoid than long-pointed as are the buds of Charlotte Armstrong, and both buds and open blooms of this new variety have an intense, spicy fragrance as contrasted with the mild fragrance of the flowers of this parent.

This new variety is distinct from its pollen parent, Night, because of its greater vigor of growth, more abundant and more mildew resistant foliage, a lighter and more glowing shade of red in the flowers which have several times as many petals as those of the pollen parent va riety. The flowers of this new variety also have a more lasting substance and heavier texture than those of Night. In addition, this new variety is very much more resistant to rose rust than its pollen parent Night which is wellknown for its susceptibility to this disease.

I claim:

A new and distinct variety of Hybrid Tea rose plant, characterized as to novelty by the color of the flowers; by the greater length and the form, of the bud as compared with other varieties in the same petalage and color class; by the upright-growing habit of the plant, of greater vigor and floriferousness than found in other very double roses in the same color class; by the abundance of large, flat, leathery leaves; the above-average resistance of the leaves to mildew for roses of the color range of this variety; and the scarcity of large and small prickles on the main stems but relatively greater number of small prickles on the branches, substantially as shown and described.
