Abstract

A miniature rose variety having a well branched, upright plant; orange-colored buds turning to light pink flowers; little or no fragrance.

Description

This present invention relates to a new and distinct variety of rose plant of the miniature class which was originated by me by crossing an unnamed variety, which itself was a cross between the variety Bangor and the variety Anabell (otherwise known as Korbell), with the pollen of the variety Nozomi.

The primary objective of this breeding was to produce a new miniature rose variety of upright habit, compact growth, and clean foliage with buds and blooms of an orange color. 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. Well branched, upright plant reaching less than 24" after one year's growth.

2. Orange colored buds turning to light pink in the aged open flowers.

3. Strong resistance to rose powdery mildew.

4. Few thorns.

5. Little or no fragrance.

Asexual reproduction of this new variety by budding, 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.

Claims (1)

I claim:

1. A new and distinct variety of rose plant of the miniature class, substantially as herein shown and described, characterized particularly as to novelty by the unique combination of its heavily branched, upright miniature plant bearing orange colored buds opening to pink mature flowers with no fragrance, and its resistance to rose powdery mildew.
