| Abstract: |
A new and distinct variety of miniature rose plant particularly distinguished by its small, bushy, upright form and its continuous year around profuse production of small, bright orange blossoms, characterized by having a light yellow central portion surrounded by orange-red petal coloration, the plant being particularly suited to pot plant culture for indoor growing, as well as being suitable for pot plant forcing for mass market production. |
| Claim: |
I claim:
1. The new and distinct variety of miniature rose plant and parts thereof, substantially as herein shown and described, characterized by its profuse and continuous production of brightorange flowers of generally small size, and by its vigorous, upright and free branching growth habit. |
| Description: |
BACKGROUND OF THE INVENTION
This new miniature rose plant originated as a seedling planted by me at Pleasanton, Calif., with seeds derived from a hybrid developed by my crossing `Amber Flash` (U.S. Plant Pat. No. 5,271) with the variety `Rhumba` (U.S. Plant Pat. No.1,919) as the pollen parent with the object of producing small, full, bushy plants for pot plant forcing with good continuous year around production of bright orange blooms and good for indoor growing. My new miniature rose variety seedling was selectedby me for propagation and test because it appeared to possess the favorable qualities that I was seeking and the selected plant was propagated by me at Pleasanton, Calif., by means of cuttings; and several generations of this new plant have demonstratedthat the favorable characteristics of the selected seedling would hold true from generation to generation and appeared to be firmly fixed.
DESCRIPTION OF THE DRAWING
My new miniature rose plant is illustrated by the accompanying photographic drawing, in which the upper view shows a fully grown potted plant of my new variety illustrating its bushy character as well as buds and flowers in various stages ofopening. The lower view shows newly opened and fully opened face views of the flower together with front and back side views of typical leaves and a cutting illustrating a bud in an early stage of opening with a new leaf, the colors shown being as closeto those herein specified as is reasonably possible to obtain by conventional photographic procedures.
DESCRIPTION OF THE NEW VARIETY
