CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority to European Community Plant Variety Office (CPVO) Plant Breeder's Rights Application No. 2024/0126 filed on Jan. 21, 2024, under 35 U.S.C. 119(f), the entire contents of which is incorporated by reference herein. The Applicant received the information for the Plant breeders' rights application directly from the Inventor. This application is co-pending with U.S. Plant Patent Applications filed for plants derived from the same breeding program that are entitled Delosperma Plant Named ‘FSDD2117’ (U.S. Plant patent application Ser. No. 18/614,655).

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Delosperma plant, botanically known as Delosperma nubigenum ‘FSDD2112’ and will be referred to hereinafter by its cultivar name, ‘FSDD2112’. 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 short stem internodes, good branching, easy rooting, cold hardiness, and unique flower and foliage coloration.

‘FSDD2112’ was selected in the Inventor's trial garden in 2018 as a single unique plant from amongst the seedlings derived from crosses made in 2016 between unnamed and unpatented plants from the Inventor's breeding program.

Asexual propagation of the new cultivar was first accomplished by stem cuttings in October of 2019 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 ‘FSDD2112’ as a unique cultivar of Delosperma.

• • 1. ‘FSDD2112’ exhibits red flowers.
  • 2. ‘FSDD2112’ exhibits unique foliage colors; green and pink tones in late winter and early spring, changing to dark green with dark purple tones in late spring to mid-summer, changing to green with red-purple in late summer.
  • 3. ‘FSDD2112’ exhibits a very good branching habit.
  • 4. ‘FSDD2112’ exhibits short stem internodes.
  • 5. ‘FSDD2112’ exhibits a very floriferous and long blooming habit; blooming from early summer into autumn.
  • 6. ‘FSDD2112’ exhibits ease of growing with no need for vernalization.
  • 7. ‘FSDD2112’ exhibits a high tolerance to heat, drought, and humidity.

The parent plants of ‘FSDD2112’ are both similar to ‘FSDD2112’ in ease of rooting and in plant habit. The parent plants of ‘FSDD2112’ both differ from ‘FSDD2112’ in having foliage coloration that is lighter red-purple, longer stems, less cold tolerance, and flowers that are light lavender in color. ‘FSDD2112’ can be most closely compared to the Delosperma cultivars ‘Jewel of Desert Ruby’ (U.S. Plant Pat. No. 23,453) and ‘WOWDAY2’ (U.S. Plant Pat. No. 25,645). Both ‘Jewel of Desert Ruby’ and ‘WOWDAY2’ are similar to ‘FSDD2112’ in having a floriferous and long blooming habit. ‘Jewel of Desert Ruby’ differs from ‘FSDD2112’ in having longer internodes and flowers that are red in color with deep pink and white centers and yellow anthers. ‘WOWDAY2’ differs from ‘FSDD2112’ in having longer stem internodes and flowers with petals that are red on the outer region and yellow towards the center of the flower surrounding yellow petaloids.

‘FSDD2112’ can also be compared to the co-pending cultivar of Delosperma nubigenum ‘FSDD2117’. ‘FSDD2117’ is similar to ‘FSDD2112’ in having short internodes, ease of growing with no need for vernalization, a high tolerance to heat, drought, and humidity, and a floriferous and long blooming habit. ‘FSDD2117’ differs from ‘FSDD2112’ in having purple flowers.
