Title: Miniature Rose Plant Named &#39;KORpot084&#39;

Description:
Botanical/commercial classification: Latin name— Rosa hybrida . Common name—Miniature Rose Plant. 
     Varietal denomination: ‘KORpot084’. 
     SUMMARY OF THE INVENTION 
     The new variety of  Rosa hybrida  Miniature Rose Plant of the present invention was created during 2014 at 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., seed parent) of the new variety was an unnamed seedling (non-patented in the United States). The male parent (i.e., pollen parent) of the new variety was the ‘KORpot28’ variety (U.S. Plant Pat. No. 25,004). 
     The parentage can be summarized as follows: 
       unnamed seedling x ‘KORpot28’
 
     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. 
     It was found that the new Miniature Rose Plant of the present invention possesses the following combination of characteristics: 
     (a) abundantly and substantially continuously forms attractive, red and pink striped colored blossoms, 
     (b) exhibits a compact growth habit, 
     (c) forms vigorous vegetation, and 
     (d) forms attractive ornamental foliage with good disease resistance. 
     The new variety well meets the needs of the horticultural industry. It can be grown to advantage as ornamentation in parks, gardens, public areas, and in residential settings. Accordingly, the plant is particularly well suited for growing in the landscape. 
     The new variety can be readily distinguished from its ancestors. More specifically, the unnamed seedling female parent (i.e., seed parent) exhibits a lower petal count and a taller growth habit compared to new variety and displays red and yellow striped flowers, whereas the new variety displays red and pink striped flowers. Additionally, the ‘KORpot28’ variety (i.e., pollen parent) exhibits a solid dark red colored flower and taller growth habit compared to the red and pink striped colored flower and shorter habit of the new variety. Moreover, new variety can be readily distinguished from other similar non-parental varieties. For example, the ‘KORpot056’ variety displays orange and yellow striped flowers, whereas the new variety displays red and pink striped flowers and has a more compact and less upright growth habit and a shorter shelf life than the ‘KORpot056’ variety. 
     The new variety has been found to undergo asexual propagation in Klein Offenseth-Sparrieshoop, Germany by a number of routes such as vegetative cuttings. Asexual propagation techniques in Germany have shown that the characteristics of the new variety are homogeneous, stable, and strictly transmissible by such asexual propagation from one generation to another. Accordingly, the new variety undergoes asexual propagation in a true-to-type manner. 
     The new variety has been named ‘KORpot084’. 
    
    
     
       BRIEF DESCRIPTION OF THE PHOTOGRAPHS 
       The accompanying photograph shows, as nearly true as it is reasonably possible to make the same in color illustrations of this character, a typical specimen of the new variety. The illustrated rose plant of the new variety was approximately twelve weeks of age and was observed at Klein Offenseth-Sparrieshoop, Germany while growing indoors on its own roots in a 10.5 cm container.

     DETAILED BOTANICAL DESCRIPTION 
     The chart used in the identification of colors is that of The Royal Horticultural Society (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 description is based on the observation of a one-year-old specimen of the new variety, observed during July, while growing in a one-gallon container on its own roots in a greenhouse in Cochranville, Pa.

     Plants of the ‘KORpot084’ variety have 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.
