1 Claim. 1

The present invention relates to a new and distinct variety of hybrid tea rose plant which I have produced by crossing the variety Contrast with the variety "Charlotte Armstrong."

The breeding above referred to has resulted in a variety which is not only widely distinct from its parents, but also from any other hybrid tea of which I am aware, these dominant distinctions being listedas follows:

(l) The new variety is a very vigorous uprightgrowing plant, with moderate branching habit and foliage which shows a high degree of resistance to mildew and anthracnose.

('2) The foliage is flat, glossy, dark green in color, medium sized ongrowth produced in the spring season but increasing in siz until it attains large proportions during the late summer and fall.

(3) The plant growth is characterized by the long, moderately. heavy stems producing a, fairly large number of medium to large thorns in the spring which, however, thereafter diminish in number until by fall the stems are relatively free of thorns. I I

(4) The flower combines a shape (hereinafter described) in both bud and open bloom with'a wide contrast between the outside surface petal color and the inside surface petal color, this inside petal color being of extreme brilliance in the opening bud and newly opened flower.

It may also be desirable to compare this new variety with its parents, and, in this connection, it may be said that it is similar in many respects to its seed parent Contrast," but differs therefrom in some very important respects: that is, (1) the foliage of the new rose is darker green in color, somewhat heavier, flatter, and attains a larger size; (2) the foliageis also highly re- 7 sistant to mildew, whereas the foliage of Contrast is quite susceptible to mildew; (3) the new rose differs from its seed parent in that the open blooms have more petals and are more symmetrical in shape; and (4) the color of the inner surface of the petals of the new variety is very much deeper andmore brilliant not only than found in Contrast, but any other variety known to me, with the possible exception of the variety called "Ronsard? (Pl. Pat. #284). In no other way does this new variety resemble the lastnamed variety.

With respect to the pollen'parenathis new varietys only resemblance lies in its resistance to mildew, and to a less pronounced degree, in the form of the open bloom. In all other respects these two varieties diller to a pronounced degree.

Asexual reproduction of this new variety shows the foregoing characteristics come true to form and are established.

In the drawing are shown specimens of the new variety, depicting as nearly as possible the various distinctions referred to above, the blooms being illustrated in their different stages from bud to full-open flower.

The following is a detailed description of the new variety, color terminology being in accordance with Robert F. Wilson's Horticultural Colour Chart with exceptions noted from Ridgways Color Standards and Nomenclature:

I claim:

A new and distinct variety of rose plant, characterized as to novelty by the vigorous uprightgrowing habit; the production of flat, glossy darkgreen medium size foliage during spring growing with increase in size until attainment of large proportions during late summer and fall; high resistance to mildew and anthracnose; by its long moderately heavy stems having a fairly large number of medium to large thorns in the spring which diminish in late season until relative freedom of thorns is reached; by the shape of bud and open bloom combined with wide contrast between outer surface petal color and inner surface petal color and extreme brilliance of the latter in the opening bud and newly opening flower, substantially as shown and described.
