Miniature rose plant named ‘KORpot094’

Abstract

A new and distinct variety of miniature rose plant, herein referred to by its cultivar name, ‘KORpot094’, is provided which forms abundantly on a substantially continuous basis attractive, light pink colored blossoms. Attractive vigorous vegetative is formed, which contrasts beautifully with the blossoms. The growth habit is upright. The new variety is well suited for providing attractive ornamentation in the landscape.

Description

Botanical/commercial classification:

Latin name: Rosa hybrida.

Varietal denomination: ‘KORpot094’.

The new variety of Rosa hybrida Miniature Rose Plant of the present invention was discovered in a cultivated area as a branch mutation of the variety ‘KORpot064’ (U.S. Plant Pat. No. 29,042) in March, 2019 at Surry, British Columbia, Canada.

It was found that the new variety of rose plant of the present invention possesses the following combination of characteristics:

• • (a) displays attractive, light pink colored blossoms,
  • (b) exhibits an upright growth habit, and
  • (c) forms vigorous vegetation.

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 of the present invention can readily be distinguished from its ancestors. More specifically, the ‘KORpot064’ variety (i.e., the parent) displays darker pink colored blossoms and less petals compared to the new variety. Moreover, the new variety can be readily distinguished from other similar non-parental varieties. For example, the ‘KORcarill’ variety (U.S. Plant Pat. No. 15,716) displays darker pink colored flowers and a lower petal count compared to the new variety.

The new variety has been found to undergo asexual propagation in Surrey, British Columbia, Canada by a number of routes, such as vegetative cuttings. Asexual propagation techniques in Canada, such as vegetative cuttings, 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 ‘KORpot094’.

The first offer for sale of the new variety was in the Spring of 2019.

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 six weeks of age and was observed at Surrey, British Columbia, Canada while growing indoors on its own roots in a 4 inch 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 six week old specimen of the new variety, observed during April, while growing in a 4 inch container on its own roots in a greenhouse in Cochranville, Pa.
