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 disclosure and/or sales prior to the filing date but less than one year prior to the effective filing date. Publications include but are not limited to listings on ecgrowers, Santa Rosa Gardens, and Skagit Gardens.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Coreopsis plant, botanically of hybrid origin and known as Coreopsis ‘Glowing Embers’ and will be referred to hereinafter by its cultivar name, ‘Glowing Embers’. The new cultivar of Coreopsis is an herbaceous perennial grown for landscape and container use.

The new Invention arose from an ongoing controlled breeding program in New Braintree, Mass. The objective of the breeding program is to develop hybrid cultivars of Coreopsis with unique and superior garden attributes. In particular, to develop cultivars that are long-lived, sturdy, exhibit a true perennial habit and cold hardy to at least U.S.D.A. Zone 5 in a wide range of flower colors and plant forms that do not require vernalization to intiate flowering.

The Inventor made a controlled cross in August of 2013 in New Braintree, Mass. between an unnamed and unpatented proprietary plant from his breeding program as the female parent and pollen that was pooled from a variety of unnamed and unpatented proprietary plants from his breeding program as the male parent. The exact characteristics of the pollen parent are therefore unknown. ‘Glowing Embers’ was selected in September of 2014 as a single unique plant amongst the resulting seedlings.

Asexual propagation of the new cultivar was first accomplished by stem cuttings under the direction of the Inventor in Kensington, Conn. in September of 2014. Asexual propagation by stem cuttings has shown that the characteristics of the new cultivar are stable and are 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 ‘Glowing Embers’ as a unique cultivar of Coreopsis.

1. ‘Glowing Embers’ exhibits a sturdy, well-branched plant habit reaching an average of 45 cm in height and 75 cm in width.
2. ‘Glowing Embers’ exhibits a floriferous and long blooming season of nearly sterile inflorescences that do not require deadheading; bloom commences in early July and lasts until frost in Kensington, Conn.
3. ‘Glowing Embers’ exhibits medium sized inflorescences with ray florets that are orange-red in color with yellow colored markings near the tips.
4. ‘Glowing Embers’ exhibits resistance to powdery mildew (Podosphaera macularis) and leafspot (Pseudomonas cichorii).
5. ‘Glowing Embers’ exhibits cold hardiness at least to U.S.D.A. Zone 5a.

The female parent of ‘Glowing Embers’ differs from ‘Glowing Embers’ in having inflorescences with ray florets that are solid dark pink in color, in not being reliably hardy in U.S.D.A. Zone 5 and in having a taller plant height and more upright plant habit. ‘Glowing Embers’ can be most closely compared to Coreopsis cultivars ‘Sunset Strip’ (U.S. Plant Pat. No. 22,670) and ‘Desert Coral’ (U.S. Plant Pat. No. 24,847). ‘Sunset Strip’ is similar to ‘Glowing Embers’ in having inflorescences with ray florets that are orange in color, thread-leaf type foliage and a similar cold hardiness. ‘Sunset Strip’ differs from ‘Glowing Embers’ in having inflorescences with ray florets that in the summer months are primarily golden yellow in color with dark orange centers, in being very fertile and produces an abundance of seed, and in being more prone to powdery mildew when grown under similar conditions in New Braintree, Mass. ‘Desert Coral’ is similar to ‘Glowing Embers’ in having inflorescences with ray florets that are orange in color and in having thread-like foliage. ‘Desert Coral’ differs from ‘Glowing Embers’ in having inflorescences with ray florets that are pink-orange with a red color eye zone, in being prone to powdery mildew when grown under similar conditions in New Braintree, Mass. and in not being cold hardy in U.S.D.A. Zone 5.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Coreopsis. The photographs were taken of a 3-month-old plant of ‘Glowing Embers’ as grown outdoors in a one-gallon container from a 30-cell plug in Kensington, Conn.

The photograph in FIG. 1 provides a side view of ‘Glowing Embers’ and shows the plant habit in bloom.

The photograph in FIG. 2 provides a close-up view of the inflorescences of ‘Glowing Embers’.

The colors in the photographs are as close as possible with the photographic and printing technology utilized and the color values cited in the detailed botanical description accurately describe the colors of the new Coreopsis.
