A new cultivar of Delosperma plant named ‘T2160’ that is characterized by its very large flowers, its very floriferous and long blooming flowering habit; blooming from early summer to early autumn, its flowers with coloration that is red-orange with light orange centers and flushed with fuchsia, its low-growing plant habit, and its high petal count.

Description

Botanical classification: Delosperma nubigenum.

Variety denomination: ‘T2160’.

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority to European Community Plant Variety Office (CPVO) Plant Breeder's Rights Application No. 2024/2720 filed on Nov. 21, 2024, under 35 U.S.C. 119(f), the entire contents of which is incorporated by reference herein.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Delosperma plant, botanically known as Delosperma nubigenum ‘T2160’ and will be referred to hereinafter by its cultivar name, ‘T2160’. The new cultivar of Delosperma is an evergreen perennial grown for container and landscape use.

The new cultivar was derived from a controlled breeding program conducted by the Inventor in Katsuta-Gun, Okayama-Pref., Japan. The overall purpose of the breeding program was to develop new cultivars of Delosperma plants with compact plant habits, floriferous blooming habits, and large flowers in a unique range of flower colors.

‘T2160’ was selected in the Inventor's trial garden in May of 2018 as a single unique plant from amongst the seedlings derived from a cross between unnamed and unpatented plants from the Inventor's breeding program.

Asexual propagation of the new cultivar was first accomplished by stem cuttings in September of 2018 by the Inventor in Katsuta-Gun, Okayama-Pref., Japan. Asexual propagation by stem cuttings has determined the characteristics of the new cultivar are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the characteristics of the new cultivar. These attributes in combination distinguish ‘T2160’ as a unique cultivar of Delosperma.

• • 1. ‘T2160’ exhibits very large flowers.
  • 2. ‘T2160’ exhibits a very floriferous and long blooming flowering habit; blooming from early summer to early autumn.
  • 3. ‘T2160’ exhibits flowers with coloration that is red-orange with light orange centers and flushed with fuchsia.
  • 4. ‘T2160’ exhibits a low-growing plant habit.
  • 5. ‘T2160’ exhibits a high petal count.

Both the female and male parents are similar to ‘T2160’ in having flowers with orange coloration. The female parent differs from ‘T2160’ in having a more vigorous growth habit. The male parent differs from ‘T2160’ in having a more compact plant habit. ‘T2160’ can be most closely compared to the Delosperma cultivars ‘T1873’ (U.S. Plant Pat. No. 34,674) and ‘W1813’ (U.S. Plant Pat. No. 34,533). ‘T1873’ is similar to ‘T2160’ in having a low growing plant habit, a high flower count, and large flowers. ‘T1873’ differs from ‘T2160’ in having flowers that are orange in color with magenta tips and yellow centers. ‘W1813’ is similar to ‘T2160’ in having a low-growing plant habit and a high flower count. ‘W1813’ differs from ‘T2160’ in having flowers that are much smaller in size and bright orange-red in color with small yellow centers.

STATEMENT REGARDING PRIOR DISCLOSURES BY THE INVENTOR

The Applicant asserts that no publications or advertisements relating to sales, offers for sale, or public distribution occurred more than one year prior to the effective filing date of this application. Any information about the claimed plant would have been obtained from a direct or indirect disclosure from the Inventor. The Applicant claims a prior art exemption under 35 U.S.C. 102(b)(1) for disclosures and/or sales that fall within a one-year grace period to the filing date. Disclosures include a website listing by Florensis.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying color photographs illustrate the overall appearance and distinct characteristics of the new Delosperma. The photographs were taken of a plant about 1 year in age (from a plug) as grown in an unheated greenhouse in Waddinxveen, Netherlands.

The photograph in FIG. 1 provides a side view of ‘T2160’ in bloom.

The photograph in FIG. 2 provides a view of a flower of ‘T2160’.

The photograph in FIG. 3 provides a close-up view of the foliage of ‘T2160’.

The colors in the photographs may differ slightly from the color values cited in the detailed botanical description, which accurately describe the colors of the new Delosperma.

DETAILED BOTANICAL DESCRIPTION

The following is a detailed description of 3.5-month-old plants of the new cultivar as grown in 15-cm containers in an unheated greenhouse in Waddinxveen, Netherlands. The phenotype of the new cultivar may vary with variations in environmental, climatic, and cultural conditions, as it has not been tested under all possible environmental conditions. The color determination is in accordance with The 2015 Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
