USPP8031P - Miniature rose plant named Lavquest - Google Patents

Abstract

A new miniature rose plant producing light pink flowers. su

SUMMARY OF THE INVENTION

The present invention relates to a new and distinct variety of rose plant of the miniature rose class, which was originated by my crossing as seed parent the variety known as `Loving Touch` and as pollen parent the variety known as `Ontario Celebration`. The varietal denomination of this new rose is `Lavquest`.

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 ease of propagation from softwood cuttings, dwarf compact habit, soft pink flower color, good shelf-life and resistance to powdery mildew.

Lavquest is particularly suited for commercial pot rose production for 4-inch or 5-inch pots because of its ease of rooting from softwood cuttings, uniform flowering habit, long flower life on the plant and bloom production in short periods.

Asexual reproduction by propagation of softwood 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.

Description

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.
