Abstract

A new miniature rose plant producing yellow flowers.

Description

SUMMARY OF THE INVENTION

The present invention relates to a new distinct variety of rose plant of the miniature rose class, which was originated by my crossing as seed parent the variety known as `Dorola` and as pollen parent the variety known as `Julie Ann`. The varietal denomination of this new rose is `Lavgold`.

Among the novel characteristics possessed by this new variety which primarily distinguish it from its parents and all other varieties of which I am aware are its color-fast, bright yellow flowers borne on a plant well suited for pot rose production. Lavgold propagates easily from soft wood cuttings and exhibits resistance to powder mildew. It has a dwarf habit suitable for pot rose production and good shelf life.

Asexual reproduction by propagation of cuttings of the new variety as performed in Somis, Calif. shows that the foregoing and other distinguishing characteristics come true to form and are established and transmitted through succeeding propagations.

BRIEF DESCRIPTION OF ILLUSTRATION

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

DETAILED DESCRIPTION OF THE NEW VARIETY

The following is a detailed description of my new variety, with color terminology in accordance with the Royal Horticultural Society Color Chart (RHSCC). The terminology used in color description herein refers to plate numbers in the aforementioned color chart.

Parentage: Seedling.

Seed parent.--`Dorola`

Pollen parent.--`Julie Ann`.
