Rose plant named `Twomin`

Abstract

A new miniature market class rose plant producing orange red flowers.

Description

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 and pollen parents two unnamed and unpatented seedlings of my creation which, although have hybrid tea in their heritage, conform best to the miniature market class. The varietal denomination of this new rose is "Twomin".

Among the novel characteristics possessed by this new variety which primarily distinguishes it from its parents and all other varieties of which I am aware are its unusual orange red flowers which open well upon aging. The new variety is especially suited for growing in outdoor gardens and exhibits improved vigor and flower production. The plant blooms freely under natural conditions.

Asexual reproduction by propagation by budding and rooting cuttings of the new variety, as performed in Pleasanton, Calif. and Watsonville, 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 a typical specimen of the flower and vegetative growth of the new variety depicted in color as nearly true as it is reasonably possible to make the same in a color illustration of this character.

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 Colour Chart (R.H.S.C.C.). The terminology used in color descriptions herein refer to plate numbers in the aforementioned color chart.
