l Claim. l

The present invention relates to a new and distinct variety of rose plant, originating as a cross between the known varieties Signora (Pl. Pat. No. 201) and Charlotte Armstrong (Pl. Pat. No. 455).

This cross was made by me primarily for the purpose of obtaining recessive genetic factors for yellow color from both parents, with the hope of, at the same time, obtaining a re-grouping of the better characteristics of each parent in the oifspring. These objectives have been accomplished in this new variety, hereinafter described, to a very satisfactory degree.

It will be apparent upon examination that this new variety of rose difiers from either of its parents in the combination of its characteristics, although it resemblances one or the other of them in several.

The dominating and distinct characteristics of this combination are as follows:

(a) Plants are of very vigorous growth normally clothed with large, leathery, and glossy foliage which unlike most foliage of its type, has a high degree of resistance to both mildew and black spot.

(2)) Long pointed to urn shaped buds opening to flowers with high centers at first, later becoming open, and with both buds and flowers in shades of color substantially described herein and to the best of my knowledge distinct from any colors heretofore known in varieties now in commerce.

Flower stems characterized by their length, strength, and relative freedom from prickles especially small ones, and with a peduncle moderately thickly covered with small thorns and spines or prickles on all but the shorter, weaker flower stem.

(at) A penetrating tea-rose fragrance to the flowers.

(e) The tendency of the flowers to burn in hot weather just before the petals drop.

Asexual reproduction shows that the characteristics hold true through succeeding propagations.

In order to more specifically point out the distinctions from the individual parents, it may be noted that this new variety differs in the following respects:

(1) It has a much longer bud than its pollen parent Signora, with a color much more predominantly in the shade popularly described as gold, or orange-yellow, and with the petals in the open flower more regularly arranged.

(2) A plant with growth habit intermediate that of the two parents, being neither as upright as Signora nor as spreading as Charlotte Armstrong.

(3) It differs from Charlotte Armstrong in the color of the bud and open flower since its seed parent is popularly described by the color terms Blood Red to Cerise varying yellow on the base of the petals. The foliage of this variety is glossy, whereas Charlotte Armstrong is classed as not glossy. This new variety has fewer prickles, both large and small, than does Charlotte Armstrong.

In the drawing are shown specimens of the plant foliage, both young and mature, and specimens of the flowers at their different-stages of development.

The following is a detailed description of the new variety, all reference to color being in accordance with the R. F. Wilsons Horticultural Colour Chart, except where indicated to be in accordance with Ridgways Color Standards and Nomenclature Type: Hardiness untested: tall; bush; outdoor; seedling; for outdoor-grown cut flowers and garden decoration.
