1. 1 . A new and distinct variety of miniature rose plant named ‘KORpot140’ characterized by the following combination of characteristics: (a) abundantly and substantially continuously forming red-colored blossoms, (b) exhibiting a compact growth habit, and (c) forming glossy, medium green foliage; substantially as herein shown and described.

Description

Latin name of genus and species of plant claimed: Rosa hybrida. Variety denomination: ‘KORpot140’. STATEMENT REGARDING PRIOR DISCLOSURES BY THE INVENTOR The first sale or offer for sale of the new plant variety was November 2024 on the ROSA DANICA website. The first sale or offer for sale of the new plant variety was by a joint inventor or another who obtained the new plant variety directly or indirectly from a joint inventor. No plants of the new variety have been sold in this country or anywhere in the world, nor has any disclosure of the new plant been made, more than one year prior the effective filing date of this application, and such sale or disclosure within one year was either derived directly or indirectly from a joint inventor. BACKGROUND OF THE INVENTION The new variety of miniature rose plant of the present invention was created by controlled breeding in 2020 in Offenseth-Sparrieshoop, Germany by artificial pollination wherein two parents were crossed which previously had been studied in the hope that they would contribute the desired characteristics. The female parent (i.e., the seed parent) of the new variety was an unnamed seedling (not patented) that was a product of the cross between an unnamed seedling and ‘KORelamur’ (not patented). The male parent (i.e., the pollen parent) of the new variety was a different unnamed seedling (not patented) that was a product of the cross between ‘RUIe057a’ (not patented) and ‘KORpolare’ (U.S. Plant Pat. No. 18,840). The parentage of the new variety can be summarized as follows: (unnamed seedling x ‘KORelamur’) x (‘RUIe057a’ x ‘KORpolare’) The seeds resulting from the above pollination were sown and small plants were obtained which were physically and biologically different from each other. Selective study resulted in the identification of a single plant of the new variety. The new plant variety has been found to undergo asexual propagation at Klein Offenseth-Sparrieshoop, Germany by a number of routes such as vegetative cuttings. Asexual propagation techniques in Klein Offenseth-Sparrieshoop, Germany, such as vegetative cuttings, have shown that the characteristics of the new plant variety are homogeneous, stable, and strictly transmissible by such asexual propagation from one generation to another. Accordingly, the new plant variety undergoes asexual propagation in a true-to-type manner. SUMMARY OF THE INVENTION It was found that the new variety of miniature rose plant of the present invention possesses the following combination of characteristics: (a) abundantly and substantially continuously forming red-colored blossoms,(b) exhibiting a compact growth habit, and(c) forming glossy, medium green foliage. The new plant variety well meets the needs of the horticultural industry. It can be grown to advantage as distinctive ornamentation in parks, gardens, public areas, and residential landscapes. Accordingly, it is particularly well suited for growing in the landscape. The new plant variety can be readily distinguished from its ancestors. More specifically, the new plant variety displays a more coral red flower color, produces between 1 and 3 blooms per stem, and exhibits a larger flower size compared to the unnamed seedling parent (i.e., the seed parent) which displays dark red colored flowers and produces blooms in clusters. Additionally, the new plant variety displays a more coral red colored blossom and a more compact growth habit compared to the different unnamed seedling parent (i.e., the pollen parent), which displays pinkish red colored flowers. Moreover, the new plant variety can be readily distinguished from non-parental related similar varieties. For example, the new plant variety displays smaller-sized foliage and a more coral red flower color, whereas the ‘KORpot003’ variety (U.S. Plant Pat. No. 23,795) displays dark red colored blossoms. The new plant variety has been named the ‘KORpot140’ variety. BRIEF DESCRIPTION OF THE PHOTOGRAPH 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 plant variety and blossoms of the new plant variety. The illustrated rose plant of the new variety was approximately sixteen weeks of age and was grown indoors on its own roots in a 10.5 cm container in Odense, Denmark. Drawing—illustrates a specimen of the plant displaying flowers at varying points of opening. DETAILED BOTANICAL DESCRIPTION The chart used in the identification of colors is that of The Royal Horticultural Society (The R.H.S. Colour Chart, 2015 edition). The terminology which precedes reference to the chart has been added to indicate the corresponding color in more common terms. The R.H.S. Colour Chart designations used herein represent the closest color observed on the majority of the specified botanical features. The description is based on a three-year-old specimen of the new variety, observed during August 2025, while growing o
