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 less than one year prior to the effective filing date would have been obtained from a direct or indirect disclosure from the Inventor under 35 U.S.C. 102.(b)(1).

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Delosperma plant of hybrid origin, botanically known as Delosperma ‘Pumpkin Perfection’ and will be referred to hereinafter by its cultivar name, ‘Pumpkin Perfection’. The new cultivar of Delosperma is a hardy herbaceous perennial grown for use as a landscape and container plant and is particularly suitable as a groundcover.

‘Pumpkin Perfection’ arose from an ongoing breeding program by the Inventor in Hudsonville, Mich. The objective was to obtain a new series of Delosperma cultivars with more floriferous blooming habits, smaller and more compact and uniform plant habits, and blooming periods that are the same amongst all cultivars in the series when grown under the same conditions.

The Inventor made a controlled cross in July of 2014 in his test garden in Hudsonville, Mich. between an unnamed proprietary plant from the Inventor's breeding program, reference no. 288-6, as the female parent and pollen that was pooled from unnamed proprietary plants of Delosperma as the male parent. The exact male parent is therefore unknown. The Inventor selected ‘Pumpkin Perfection’ as a single unique plant in June of 2016 from the resulting seedlings.

Asexual reproduction of the new cultivar was first accomplished by stem tip cuttings in April of 2015 in Hudsonville, Mich. Asexual propagation by stem tip cuttings has determined that the characteristics 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 ‘Pumpkin Perfection’ as a unique cultivar of Delosperma.

• • 1. ‘Pumpkin Perfection’ exhibits a floriferous blooming habit with an average of 47 flowers per plant as a 10-week-old plant grown in a 1-quart container started from a 128-cell plug.
  • 2. ‘Pumpkin Perfection’ exhibits orange flowers with white centers.
  • 3. ‘Pumpkin Perfection’ exhibits very compact and tight mounds of foliage that do not become long or leggy during the summer growing months.
  • 4. ‘Pumpkin Perfection’ exhibits strong re-bloom during the entire growing season and into late fall.
  • 5. ‘Pumpkin Perfection’ exhibits a small plant size reaching an average of 3.8 cm in height and 38 cm in width.
  • 6. ‘Pumpkin Perfection’ exhibits uniform rooting that occurs in just 10 days.
  • 7. ‘Pumpkin Perfection’ exhibits a uniform blooming period with other plants in the series.

The seed parent plant of ‘Pumpkin Perfection’, no. 288-6, differs from ‘Pumpkin Perfection’ in having a 30% taller plant habit, 45% less flowers and flowers that are pastel pink in color. ‘Pumpkin Perfection’ can be most closely compared to the cultivars ‘Jewel of Desert Topaz’ (U.S. Plant Pat. No. 23,492) and ‘WOWDOY3’ (U.S. Plant Pat. No. 25,600). ‘Jewel of Desert Topaz’ is similar to ‘Pumpkin Perfection’ in having orange flowers and a flowering period of late spring through fall. ‘Jewel of Desert Topaz’ differs from ‘Pumpkin Perfection’ in having less flowers that are darker orange in color, 23 flowers per 10-week old plant, a taller plant height varying between 56 cm and 71 cm and less floriferous re-bloom in fall. ‘WOWDOY3’ differs from ‘Pumpkin Perfection’ in having flowers that are 25% larger in size, less flowers; an average of 31 flowers per 10-week old plant, a taller plant height of 10 cm and a plant width of 91 cm. ‘Pumpkin Perfection’ can also be compared to cultivars with co-pending patent applications from the same breeding program that have the same blooming periods. ‘Coconut Crush’ differs from ‘Pumpkin Perfection’ in having white flowers, ‘Fig Fusion’ differs from ‘Pumpkin Perfection’ in having hot pink flowers, ‘Banana Blast’ differs from ‘Pumpkin Perfection’ in having yellow flowers, ‘Saucy Strawberry’ differs from ‘Pumpkin Perfection’ in having red-pink flowers, and ‘Tangerine Tango’ differs from ‘Pumpkin Perfection’ in having red-orange flowers.
