Rose plant Korflug

Abstract

A new hybrid tea rose with large, long lasting flowers having pink petals of unusual thickness. The rose is suitable for greenhouse production, presenting buds of cutting size on medium length stems.

Description

This present invention relates to a new and distinct variety of rose plant of the hybrid tea class which was originated by us by crossing an unnamed variety with the variety Lady Like, non-patented.

The primary objective of this breeding was to produce a new rose variety suitable for greenhouse cut flower production in the pink color range. This objective was substantially achieved along with other desirable improvements as evidenced by the following unique combination of characteristics which are outstanding in the new variety and which distinguish it from its parents, as well as from all other varieties of which we are aware:

1. Light pink bud and open flower.

2. Unusually stiff, firm petals, approximately 25 per flower.

3. Production of a suitable quantity of medium length stems under greenhouse conditions.

4. Resistance to mildew.

5. Little or no fragrance.

Asexual reproduction of this new variety by budding, as performed at Irvine and Wasco, Calif., shows that the foregoing characteristics and distinctions come true to form and are established and transmitted through succeeding propagations.

The accompanying illustration shows typical specimens of the vegetative growth and flowers of this new variety in different stages of development, depicted in color as nearly true as it is reasonably possible to make the same in a color illustration of this character.

The following is a detailed description of our new rose cultivar with color in terminology in accordance with The Royal Horticultural Society Colour Chart except where ordinary dictionary significance of color is indicated.
