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 ‘Tangerine Tango’ and will be referred to hereinafter by its cultivar name, ‘Tangerine Tango’. 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.

‘Tangerine Tango’ 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. 275-3, 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 ‘Tangerine Tango’ 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 ‘Tangerine Tango’ as a unique cultivar of Delosperma.

• 1. ‘Tangerine Tango’ exhibits a floriferous blooming habit with an average of 65 flowers per plant as a 10-week-old plant grown in a 1-quart container started from a 128-cell plug.
• 2. ‘Tangerine Tango’ exhibits red-orange flowers with white centers.
• 3. ‘Tangerine Tango’ exhibits very compound and tight mounds of foliage that do not become long or leggy during the summer growing months.
• 4. ‘Tangerine Tango’ exhibits a strong re-blooming habit during the entire growing season and into late fall.
• 5. ‘Tangerine Tango’ exhibits a height of 3.8 cm and 38 cm in width.
• 6. ‘Tangerine Tango’ exhibits uniform rooting that occurs in just 10 days.
• 7. ‘Tangerine Tango’ exhibits a uniform blooming period with other plants in the series.

The seed parent plant of ‘Tangerine Tango’, no. 275-3, differs from ‘Tangerine Tango’ in having a 30% less compact plant habit, 50% less flowers and flowers that lacked bright white centers. ‘Tangerine Tango’ can be most closely compared to the cultivars ‘Jewel of Desert Ruby’ (U.S. Plant Pat. No. 23,453) and ‘WOWDOY3’ (U.S. Plant Pat. No. 25,600). ‘Jewel of Desert Ruby’ is similar to ‘Tangerine Tango’ in having orange flowers with white centers and a flowering period of late spring through fall. ‘Jewel of Desert Ruby’ differs from ‘Tangerine Tango’ in having less flowers; 40 flowers per 10-week old plant, a taller plant height varying between 56 cm and 71 cm, and a less floriferous re-bloom in fall. ‘WOWDOY3’ is similar to ‘Tangerine Tango’ in having a similar blooming habit during the summer and succulent leaves that are green in color. ‘WOWDOY3’ differs from ‘Tangerine Tango’ in having larger flowers and less flowers; 35 flowers per 10-week old plant, and a less compact plant habit with a taller plant height of 10 cm, and wider plant width of 91 cm. ‘Tangerine Tango’ 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 ‘Tangerine Tango’ in having white flowers, ‘Fig Fusion’ differs from ‘Tangerine Tango’ in having hot pink flowers, ‘Pumpkin Perfection’ differs from ‘Tangerine Tango’ in having orange flowers, ‘Saucy Strawberry’ differs from ‘Tangerine Tango’ in having red-pink flowers, and ‘Banana Blast’ differs from ‘Tangerine Tango’ in having red-orange flowers.
