Application December 1 Claim.

The present invention relates to a new and distinct variety of rose plant of the Floribunda class, originated by crossing an unnamed Dickson seedling and the well-known Lord Lonsdale variety.

The object in view in producing the present variety was to obtain the free flowering characteristic and vigor of the bush of the Dickson seedling in a plant retaining the deep rich color of the Lord Lonsdale variety. Not only was this objective realized in this new variety, but other Very desirable characteristics were obtained, with the result that the new rose produces great quantities of clusters and groups of flowers, especially suited for corsage and basket work and other special arrangements.

The new rose is distinctive because, instead of the small bush, of the Lord Lonsdale type, a large one is established particularly suitable for the purpose of greenhouse cut flowers to be used in the Sweetheart class of roses.

This new rose is also distinctive for its continuous blooming habit and the production of Light Cadmium Yellow buds which are strikingly set 01f by the Dark Cress Green foliage.

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

The following is a detailed description of the new variety, all color terminology being in accord with Ridgways Color Standard:
