Rosa plant named ‘RUIZ012A’

Abstract

A new cultivar of Rosa plant named ‘RUIZ012A’ that is characterized by a compact habit, long life and red flowers.

Description

Botanical classification: Rosa.

Variety denomination: ‘RUIZ012A’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Rose plant botanically known as Rosa and hereinafter referred to by the cultivar name ‘RUIZ012A’.

The new cultivar is the product of a breeding program conducted by the inventor in a cultivated area of Hazerswoude, The Netherlands. The objective of the breeding program was to develop miniature roses with attractive flower and foliage colors. ‘RUIZ012A’ is a hybrid that originated from the induced hybridization of the female or seed parent Rosa ‘Ruiscar’ (not patented) and the male or pollen parent Rosa ‘Poulracos’ (not patented). The cultivar ‘RUIZ012A’ was selected by the inventor in May of 2000 as a single plant within the progeny of the stated cross in a controlled environment of Hazerswoude, The Netherlands.

The closest comparison plant is Rosa ‘Ruiskjol’ (U.S. Plant Pat. No. 12,672) ‘RUIZ012A’ is distinguishable from ‘Ruiskjol’ by larger lighter color flowers, leaves with a dark green upper side and a grey-green under side and a more compact habit.

The new cultivar ‘RUIZ012A’ is distinguishable from the female parent Rosa ‘Ruiscar’ in having dark red flowers. The flowers of ‘Ruiscar’ are pink with a yellow center. The new cultivar ‘RUIZ012A’ is distinguishable from the male parent Rosa ‘Poulracos’ in having larger flowers.

Asexual reproduction by cuttings of the new cultivar ‘RUIZ012A’ was first performed in December of 2000 in Hazerwsoude, The Netherlands. Since that time, under careful observation, the unique characteristics of the new Rose cultivar have been uniform, stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

The following represent the distinguishing characteristics of the new Rosa cultivar ‘RUIZ012A’. These traits in combination distinguish ‘RUIZ012A’ as a new and distinct cultivar apart from all other existing varieties of Rosa known to the inventor. ‘RUIZ012A’ has not been tested under all possible conditions and phenotypic differences may be observed with variations in environmental, climatic, and cultural conditions, however, without any variance in genotype.

Rosa ‘RUIZ012A’ exhibits a compact habit.

Rosa ‘RUIZ012A’ exhibits red flowers.

Rosa ‘RUIZ012A’ exhibits a long plant life.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying drawing illustrates the distinguishing traits of Rosa ‘RUIZ012A’. The plant in the drawing is 12 weeks old and was glass greenhouse grown in a 10 cm. container. The drawing shows the overall plant. The photograph was taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.

BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed description of the new Rosa cultivar named ‘RUIZ012A’. Data was collected in Amstelveen, The Netherlands from 12 weeks old glass greenhouse grown plants in a 10 cm. container. The time of year was March and the average temperature was 18° Centigrade during the day and 16° Centigrade at night. The light level was 5000 Lux. No photoperiodic treatments were used. Bonsi growth retardant was applied. Color determinations are in accordance with The Royal Horticultural Society Colour Chart 1995 except where general color terms of ordinary dictionary significance are used. The growing requirements are similar to the species.
