A new and distinct greenhouse and garden rose plant particularly distinguished by its continuous and profuse production of very large flowers having, in general, an Empire Rose coloration from Spring to late Fall for greenhouse-garden culture with flowers borne on strong, vigorous, upright stems of medium length on a plant having a vigorous, upright and sturdy growth habit with abundant foliage.

Description

BACKGROUND OF THE NEW PLANT

This new variety of rose plant originated as a seedling of a hybrid produced by me at my nursery at Carlsbad, Calif., the parent hybrid resulting from my crossing of the variety Emily Post (U.S. Plant Pat. No. 3,749) as a seed parent with pollen from an unnamed and unpatented seedling growing in my collection of rose plants maintained for breeding purposes; the object of this crossing for the said hybrid being the development of a better producing pink rose plant having improved health and vigor. The selected seeding appeared very well to achieve my objectives and accordingly, I propagated that seedling by means of cuttings as well as by budding at the DeVor nurseries at Pleasanton, Calif. with very satisfactory results and at my direction, such propagation was continued through several successive generations which demonstrated conclusively that the novel characteristics of my selected seedling would hold true from generation to generation and appeared to be firmly fixed. As a result of that accomplishment, propagation is now being carried on by DeVor Nurseries, Inc. at Orland, Calif.

DESCRIPTION OF THE DRAWING

My new rose plant is illustrated by the accompanying photographic drawing which in full color shows a face view of a fully opened bloom demonstrating the flower form and the nature of its petals, the colors shown being as nearly true to those herein specified as is reasonably possible to obtain by conventional photographic procedures.

DESCRIPTION OF THE NEW VARIETY
