Miniature rose plant named ‘KORaroma12’

Abstract

A new and distinct variety of miniature rose plant, referred to by its cultivar name, ‘KORaroma12’, is described. The new variety forms in abundance on a substantially continuous basis attractive, pastel-yellow-colored blossoms. The vegetation is vigorous, and the growth habit is compact. Attractive dark green foliage is formed. Additionally, the new variety is particularly well suited for growing as distinctive ornamentation in the landscape.

1. A new and distinct variety of miniature rose plant named ‘KORaroma12’ characterized by the following combination of characteristics: (a) abundantly and substantially continuously forms attractive, pastel-yellow- colored blossoms, (b) exhibits a compact growth habit, (c) forms vigorous vegetation, and (d) forms attractive ornamental matte foliage; substantially as herein shown and described.

Description

BRIEF DESCRIPTION OF THE PHOTOGRAPH

(1) The accompanying photograph shows, as nearly true as it is reasonably possible to make the same in a color illustration of this character, a typical specimen of the new variety and blossoms of the new variety. The illustrated rose plant of the new variety was approximately twelve weeks of age and was grown indoors in a 10.5 cm container on its own roots at Odense, Denmark.

(2) The drawing sheet illustrates a specimen of the plant displaying flowers at varying points of opening.

DETAILED BOTANICAL DESCRIPTION

(4) The new ‘KORaroma12’ variety has not been observed under all possible environmental conditions to date. Accordingly, it is possible that the phenotypic expression may vary somewhat with changes in light intensity and duration, cultural practices, and other environmental conditions.
