CROSS REFERENCE TO RELATED APPLICATIONS

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 ‘WOWDOY3’ (U.S. Plant patent application Ser. No. 13/987,585), Delosperma Plant Named ‘WOW2011-1’ (U.S. Plant patent application Ser. No. 13/987,575), Delosperma Plant Named ‘WOWDRY1’ (U.S. Plant patent application Ser. No. 13/987,588), Delosperma Plant Named ‘WOWDRW5’ (U.S. Plant patent application Ser. No. 13/987,584), and Delosperma Plant Named ‘WOWDW7’ (U.S. Plant patent application Ser. No. 13/987,577).

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Delosperma plant, botanically known as Delosperma cooperi ‘WOWDAY2’ and will be referred to hereinafter by its cultivar name, ‘WOWDAY2’. The new cultivar of Delosperma is an herbaceous 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 low-growing and well-spreading growth habits combined with long flowering periods and a unique range of flower colors.

‘WOWDAY2’ was selected in the Inventor's trial garden in summer of 2011 as a single unique plant from amongst the seedlings derived from self crossing an unnamed plant from the Inventor's breeding program, ref. code HANADAY 1003, in summer of 2010.

Asexual propagation of the new cultivar was first accomplished by softwood stem cuttings in summer of 2011 by the Inventor in Katsuta-Gun, Okayama-Pref., Japan. Asexual propagation by softwood 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 ‘WOWDAY2’ as a unique cultivar of Delosperma.

• • 1. ‘WOWDAY2’ exhibits a compact and horizontal plant habit.
  • 2. ‘WOWDAY2’ exhibits a very floriferous and long blooming flowering habit; blooming about 8 months.
  • 3. ‘WOWDAY2’ exhibits large flowers with petals that are red on the outer region and yellow towards the center of the flower surrounding yellow petaloids.

The parent plant of ‘WOWDAY2’, ref. code HANADAY 1003, differs from ‘WOWDAY2’ in having a taller plant habit and in blooming for a shorter time period. ‘WOWDAY2’ can be most closely compared to the cultivar ‘Jewel of Desert Garnet’ (U.S. Plant Pat. No. 23,471), which is similar to ‘WOWDAY2’ in having a horizontal plant habit and red coloration to the petals. ‘Jewel of Desert Garnet’ differs from ‘WOWDAY2’ in having smaller flowers that have pink on the lower portion of the petals and pink petaloids, in having a shorter bloom period, and in having a shorter plant height. ‘WOWDAY2’ can also be compared to cultivars with co-pending patent applications from the same breeding program, which are similar in plant height and in having large flowers.

‘WOWDRY1’ has flowers with petals that are magenta pink on the outer region and yellow and white towards the center of the flower surrounding yellow and white petaloids.

‘WOW2011-1’ has flowers with yellow petals and yellow-green petaloids.

‘WOWDRW5’ has flowers with petals that are magenta pink on the outer region and white towards the center of the flower surrounding white petaloids.

‘WOWDW7’ has flowers with white petals and white petaloids.

‘WOWDOY3’ has flowers with petals that are orange on the outer region and yellow towards the center of the flower surrounding yellow petaloids.
