ROSE PLANT Roy L. Byrum,. Richmond, Ind., assignor to Joseph H. Hill Company, Richmond, Ind., a corporation of Indiana Application September 10, 1941, Serial No. 410,338

1 Claim.

The present invention relates to a new and distinct variety of rose plant of the hybrid tea class, the result of adefinite efiort to obtain a rose responsive to greenhouseforcing methods designed to produce high quality and long stem .cut flowers. 5

In-carrying out this objective, I crossed the well-known greenhouse forcing variety Joanna Hill, of the yellow color range, and R. M. S. Queen Mary (Plant Patent No. 249) of the pink range, thereby producing .the present rose having the following primary characteristics:

(a) Produces long stems in greenhouse without artificial means, or from the out without pinching;

(b) Produces long buds so desirable in cut flowers; I v r (c) Provides a goodsummer forcing rose as well as a winter one; and

(d) Is resistant to mildew and blackspot.

In addition to the foregoing, its main distinguishing feature is the unusual color combination of its flowers, a color unlike that of any forcing variety of which I am aware, and illustrated as nearly correct as possible in the accompanying drawing in the various stages of development.

The color terminology herein employed is in accord with Ridgways Color Standards where indicated by plate numbers, otherwise with general dictionary meaning.

The following is a detailed description of this new variety of rose:

cut flowers.

This description of a newly opened flower was made from a rose grown in a greenhouse during the month of July, 1941, at Richmond, Indiana:

CoZo1'.Outside petal, outside surface-Venetian Pink, Plate XIII, with Alizarine Pink edge on each edge, Plate XIII, of Lemon Chrome veins, Plate IV; inside surface-Livid Pink, Plate XXVII.

Inner petal, outside surface-01d Rose, Plate XIII; inside surface-Light Coral Red, Plate XIII, with tip edge Light Jasper Red, Plate XIII. Base in each of above instances-Lemon Chrome, Plate IV.

This description was made from a rose that was open for three days in a greenhouse in the month of August, 1941, at Richmond, Indiana:
