Rose plant

Abstract

A climber rose variety having vigorous climbing plant, blooming in large clusters on terminals and from laterals, throughout the growing season, of generally lavender color.

Description

This present invention relates to a new and distinct variety of rose plant of the climber class which was originated by crossing the unpatented variety Yesterday with the unpatented variety Nastarana.

The primary objective of this breeding was to produce a new rose variety of the climber class, with everblooming capabilities, suitable for use in landscape or ground cover situations. 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 I am aware:

1. Plant blooms on short basal canes and repeats throughout the growing season;

2. Established plants produce canes 6' or longer blooming in large clusters at the terminals;

3. Lateral shoots produce abundant blooms;

4. Blooms are small, nearly single; and

5. Bud and flower color is lavender.

Asexual reproduction of this new variety by cuttings, as performed at 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 my 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:
