ABSTRACT OF THE DISCLOSURE A new variety of rose plant bearing velvety rich red, non-blueing, slow opening flowers of great substance borne individually on long well proportioned stems; this new variety being a large flowered floribunda with high winter production and rapid cycling of bloom periods.

Background of the inventin.This new variety of rose plant originated as a seedling of the variety Christian Dior (Plant Patent 1943), the pollen parent being Rumba (Plant Patent 1919), and was developed by me in 1963 during the course of a breeding program carried on by me at Livermore, Calif. since 1955 with the object of producing an improved long stemmed red rose suitable for greenhouse culture for commercial cut flower production. The new plant was observed to possess unusual and valuable characteristics in that it produced profusely very attractive, high centered blooms having extra-longlasting quality, both on the plant and as a cut flower. The new plant was found to flower continuously, during all seasons, and to be little affected by wet or hot Weather. Also the plant was found to have a free branching and vigorous growth habit, producing long straight stems and abundant foliage, and being of upright compact form averaging 30 to 36 inches in height.

This new variety of red rose plant has been asexually reproduced by me and under my direction at Livermore, Calif. and successive generations produced by budding have demonstrated that the novel and advantageous characteristics of the new variety are fixed and hold true in all respects from generation to generation. Propagation and field testing has also been done at Hamilton City, Calif. and Phoenix, Ariz., and commercial scale propagation is now being done at these places as well as at Livermore, Calif.

Fruit The fruit is fertile, ovoid in shape and is of an Orient Red Color 819 at maturity.

My new red rose plant variety most nearly resembles Garnette Supreme (Plant Patent 1,318). Differences from Garnette Supreme, however, are found in that the new variety has stems that are straighter and from 30 to 40% longer; has 30 to 40% greater peduncle length; a longer and more slender bud, with no flats; a larger open flower of brighter color, free from magenta and with velvety petal texture; and has much less tendency to throw clusters.

The new variety also resembles Tommy Bright (Plant Patent 2,129) in general appearance but differs from Tommy Bright by producing blooms of brighter color,

with less magenta, and with better proportioned stems and foliage growth. Also, my new variety has bright, pointed buds as compared with the dark, flat buds of Tommy Bright, has better keeping quality for its blooms and is faster cycling .in its blooming habit.

Iclaim:

1. A new and distinct variety of rose plant substantially as herein shown and described, characterized by its velvety rich red, non-blueing, slow opening flowers mostly borne individually on long stems and possessing exceptionally long vase-life; and by the rapid cycling of its bloom period and its high winter production.
