Abstract

A distinctive cultivar of miniature rose plant named ‘Ruiskjol’, characterized by its glossy dark green leaves; large double scarlet red-colored flowers; and excellent postproduction longevity.

Description

BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of the miniature rose class, botanically known as Rosa hybrida, and hereinafter referred to by the cultivar name Ruiskjol.
The new miniature rose is a naturally-occurring whole plant mutation of the commercial Rosa hybrida cultivar Ruimats, disclosed in U.S. Plant Pat. No. 10,820. The new minature rose was discovered and selected by the Inventor in a greenhouse in Hazerswoude, The Netherlands. Plants of the new miniature rose differ from plants of the parent cultivar primarily in flower color as plants of the cultivar Ruimats have dark orange-colored flowers.
Asexual reproduction of the new cultivar by cuttings taken at Hazerswoude, The Netherlands, has shown that the unique features of this new miniature rose plant are stable and reproduced true to type in successive generations of asexual reproduction.
SUMMARY OF THE INVENTION
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Ruiskjol’. These characteristics in combination distinguish the new miniature rose plant as a new and distinct cultivar:
1. Glossy dark green leaves.
2. Large double scarlet red-colored flowers.
3. Excellent postproduction longevity.
The new miniature rose plant has not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in environment such as temperature and light level, without, however, any variance in genotype.
BRIEF DESCRIPTION OF PHOTOGRAPH
The accompanying colored photograph illustrates typical plants of the new miniature rose plant, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which more accurately describe the actual colors of the new miniature rose. The photograph comprises a top perspective view of a large container of multiple plants of the new miniature rose grown in Keller, Tex.
DETAILED BOTANICAL DESCRIPTION
The following observations and measurements describe plants grown in Keller, Tex., in 15-cm containers under conditions which closely approximate commercial outdoor production conditions during the summer and early autumn. Plants used for the description were about 15 weeks old.
In the following description, color references are made to The Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used.
