Abstract

A shrub Rosa hybrida rose plant is disclosed having old-fashioned-style pale pink flowers with green centers, and repeat flowering.

Description

The present invention relates to a new and distinct variety of rose plant of the shrub class which was originated by me by crossing the variety "Wife of Bath" with the variety "Graham Thomas". The variety "Wife of Bath" (unpatented) has cup-shaped flowers of a slightly darker pink than AUSCOUNTRY and has rather weak growth. "Graham Thomas" (unpatented) has golden-yellow, cup-shaped flowers and possesses vigorous, bushy growth.

The primary objective of this breeding was to produce a new rose variety having the repeat flowering of its parents with olf-fashioned-type flowers. The 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 I am aware:

1. Old-fashioned-style flowers having pale pink color and green centers resulting from enlarged green-colored styles that extend above the small petals in the middle of the flowers; and

2. Repeat flowering.

Asexual reproduction of this new variety by budding, as performed at Albrighton, Wolverhampton, England, 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 vareity 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 my new rose cultivar with color descriptions using terminology in accordance with The Royal Horticultural Society (London) Color Chart, except where ordinary dictionary significance of color is indicated.
