WA LTEI'? E. LAM/"EH75 United States Patent 3,162 ROSE PLANT Walter E. Lammerts, Freedom, Calif., assignor to Germains Inc., Los Angeles, Calif. Filed Sept. 25, 1970, Ser. No. 75,794 Int. Cl. A01h 5/00 US. Cl. Plt.22 1 Claim ABSTRACT OF THE DISCLOSURE greenhouse conditions produces blooms throughout the entire year that have excellent lasting quality as cut flowers.

BACKGROUND OF THE INVENTION My new variety of rose plant resulted from breeding efforts carried on by me at Livermore, Calif., since 1953 with the object of obtaining a floribunda variety that would approximate the delicate coloring of Peace (PP. 591) and at the sametime maintain hybrid vigor and productiveness. This was accomplished by crossing Peace with the wholly unrelated variety Rumba (P.P. 1,919) and in 1963 the present new variety was discovered among seedlings so produced. The new plant, in addition to the distinctively novel coloring of its blooms, was found to have the vigor and productiveness of Rumba, as well as the firm glossy foliage of both parent varieties, and asexual propagation of this plant at Livermore, Calif., by budding, has shown these advantages to be firmly fixed and to hold true from generation to generation.

Propagation of this new variety of rose plant is now being carried on at Livermore, Califi; at Hamilton City, Calif.; and at Phoenix, Ariz. The following specification, however, is based upon observations made under greenhouse conditions at Livermore, Calif., and at Salinas, Calif., and under nursery field conditions at Hamilton City, Calif.

DESCRIPTION OF THE DRAWINGS My new variety of rose plant is illustrated by the accompanying photographic representation in which the upper view shows the flower in various stages of development from bud, when calyx splits, to fully opened bloom; and the lower view shows front and back sides of typical leaves, portions of young and mature wood, and a flowering stem with a new bud.

Siz'. /s to /6 inch by /8 to inch.

Yellow-Green 15213 in color. Discoloration: Colors blend together after full bloom. Persistence: Flowers hang on and drop cleanly without drying on plant. Petals stay on stem for 18 to 22 days.

Disease Resistance: Plant resists mildew and rust as ob- Fruit Fruit is fertile and of round shape. Color at maturity is Orange-Red 30C.

The principal and outstanding distinction of my new variety of rose plant over any other fiuoribunda varieties resides in the very clear and substantially uniform red margin which extends around the entire periphery of each petal, except for'the base. In the opening stages of the bloom this margin contrasts very sharply with the basic ivory color of the rest of the petal, providing a very distinctive and pleasing appearance.

Another distinctive characteristic of the new variety is the coloring of the bark which turns to a reddish-brown as the bloom matures, but only in that portion or area exposed to direct sunlight. Any shaded portion, no matter how small, retains the original green color.

The variety of rose plant'v most nearly resembled by my new variety isPeppermint (P1.P.' 2549) My new variety, however, is distinguished from Peppermint by the clear band of color at the margin of the petals whereas Peppermint has a diffusion of colors. Furthermore, my new variety has much more of the basic ivory color in its bloom and more yellow on the inside petals; a more glossy foliage than Peppermint; and a more compact and shorter growing habit. I p

A particular advantage of my new rose plant is. that it is a free producing fiuoribunda variety that produces blooms throughout the entire year under greenhouse conditions and the number and texture of the petals affords excellent lasting quality to the blooms as cut flowers. Also,

the plant foliage is outstanding both as to quantity and appearance. I i

I claim: i i 1. A new and distinctive variety of fluoribunda rose plant substantially as herein shown and described, characterized by the generally uniform red margin extending along the entire edge of each petal of the blooms and contrasting sharply with the basic generally ivory color of the petal body; and in the reddish-brown coloration of the bark which occurs only in the portions exposed to direct sunlight as the bloom matures.
