Miniature rose plant named `JACpupot`

Abstract

A miniature rose plant having the unique combination of its flower color; thick, numerous petals (55 to 60); and compact growth habit.

Description

The 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 seedling with the variety JACliang (U.S. Plant Pat. No. 8,402.

The primary objective of this breeding was to produce a new rose variety having the plant habit and blooming habit of the female parent combined with the color and higher petal number of the male parent. The objective was substantially achieved, along with other desirable improvements, as evidenced by the following unique combination of characteristics that are outstanding in the new variety and that distinguish it from its parents, as well as from all other varieties of which I am aware:

1. Vigorous, compact growth habit;

2. High petal count;

3. Novel flower color;

4. Thick petal substance; and

5. Free development of basal shoots from bottom of plant providing occasional small clusters of flower.

Asexual reproduction of this new variety by softwood cuttings, as performed at Wasco and Somis, Calif., shows that the foregoing characteristics and all other features 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 descriptions using terminology in accordance with the Royal Horticultural Society (London) Colour Chart, except where ordinary dictionary significance of color is indicated.
