Abstract

A new variety of rose plant of the shrubb class distinctive in its character by its fully double, pure pink flowers with abundant continual blooming, and the unusual shaping of the flowers.

Description

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct variety of shrub roses, said new variety originating as a single seedling resulting from a definite effort to produce an improvement in this class of rose.

BRIEF SUMMARY OF THE INVENTION

Primary features of this new variety which connote a distinctive advance over existing types are the vigorous abundant and continual blooming that occurs for 5 months taken with the perfection of the fully double flowers of an old-fashioned shape, more particularly apparent in the accompanying illustration of a specimen thereof.

The accompanying illustration shows typical cultivar flowers of this new cultivar in various stages of development, depicted in color as nearly true as is possible to make the same in color illustrations of this character.

DETAILED BOTANICAL DESCRIPTION

The following is a detailed description of the new variety, color terminology being in accordance with the "Methuen Handbook of Colour" published by Eyre Methuen Ltd (1963).

Variety denomination (in accordance with the UPOV Convention):

Ausdimindo (Cultivar Trade Name: Bibi Maizoon).

Type: Hardy, outdoor, bushy, garden decoration.

Class: Shrub.

Propagation: This variety holds its distinguishing characteristics through succeeding propagations by budding.

Asexual reproduction of the new cultivar by budding has taken place at a nursery in Albrighton, Nr. Wolverhampton, England and was derived as follows:

Female parent (seed parent): The Reeve (non-patented).

Male parent (pollen parent): Chaucer (non-patented).

The operation of the artificial pollination is therefore expressed by the following: The Reeve.times.Chaucer.

The following observations are made of specimens grown outdoors in England.
