Abstract
A new cultivar of hybrid Coreopsis plant named ‘Firewheel’ that is characterized by its compact plant habit reaching an average of 50 cm in height and 70 cm in width, its floriferous and long blooming season of its sterile inflorescences that do not require deadheading; bloom commences in late-June and lasts until frost in Kensington, Conn., its large sized inflorescences with ray florets that are somewhat folded (not flat), ruffled, with serrated tips and are red-orange in color with yellow near the tips, its resistance to powdery mildew and leafspot, its cold hardiness at least to U.S.D.A. Zone 4, and its ease of propagation as cuttings can be taken throughout the growing season.
Description
Botanical classification: Coreopsis hybrid.
Variety denomination: ‘Firewheel’.
The present invention relates to a new and distinct cultivar of Coreopsis plant, botanically of hybrid origin and known as Coreopsis ‘Firewheel’ and will be referred to hereinafter by its cultivar name, ‘Firewheel’. 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 4 in a wide range of flower colors and plant forms.
The Inventor made a controlled cross in August of 2015 in New Braintree, Mass. between an unnamed and unpatented proprietary plant from his breeding program as the female parent (ref. code N2 14-12) 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. ‘Firewheel’ was selected in September of 2016 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 2016. 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.
The following traits have been repeatedly observed and are determined to be the characteristics of the new cultivar. These attributes in combination distinguish ‘Firewheel’ as a unique cultivar of Coreopsis.
- 1. ‘Firewheel’ exhibits a compact plant habit reaching an average of 50 cm in height and 70 cm in width.
- 2. ‘Firewheel’ exhibits a floriferous and long blooming season of its sterile inflorescences that do not require deadheading; bloom commences in late-June and lasts until frost in Kensington, Conn.
- 3. ‘Firewheel’ exhibits large sized inflorescences with ray florets that are somewhat folded (not flat), ruffled, with serrated tips and are red-orange in color with yellow near the tips.
- 4. ‘Firewheel’ exhibits resistance to powdery mildew and leafspot.
- 5. ‘Firewheel’ exhibits cold hardiness at least to U.S.D.A. Zone 4.
- 6. ‘Firewheel’ exhibits ease of propagation as cuttings can be taken throughout the growing season.
The female parent of ‘Firewheel’ differs from ‘Firewheel’ in having flowers that are pink in color and in being very fertile causing flower production to stop once seed has set. ‘Firewheel’ can be most closely compared to Coreopsis cultivars ‘Daybreak’ (U.S. Plant Pat. No. 27,138) and ‘Darling Clementine’ (U.S. Plant Pat. No. 31,843). ‘Daybreak’ is similar to ‘Firewheel’ in being resistant to powdery mildew and leaf spot, in having inflorescences with ray florets that are yellow in color with a red eye, and in having a long bloom season that does not require deadheading. ‘Daybreak’ differs from ‘Firewheel’ in having inflorescences with ray florets that are deeper golden yellow in color with a defined red eye, in being hardy to U.S.D.A. Zone 5, and in producing good cutting material only prior to onset of flowers versus all season. ‘Darling Clementine’ is similar to ‘Firewheel’ in having inflorescences with ray florets that are yellow and orange in color, in having a long bloom season that does not require deadheading, in being resistant to powdery mildew and leaf spot, and in being hardy to U.S.D.A. Zone 4. ‘Darling Clementine’ differs from ‘Firewheel’ in having inflorescences with ray florets that are relatively flat (not folded), are medium orange in color with much less ruffled and serrated tips.
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 a listing on a website by Skagit Horticulture.
The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Coreopsis. The photographs were taken of a 4-month-old plant of ‘Firewheel’ as grown outdoors in one-gallon containers in Kensington, Conn.
The photograph in FIG. 1 provides a view of ‘Firewheel’ in bloom.
The photograph in FIG. 2 provides a close-up view of an inflorescence of ‘Firewheel’.
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.
The following is a detailed description of 4-month-old plants of ‘Firewheel’ as grown outdoors in one-gallon containers in Belchertown, Mass. The phenotype of the new cultivar may vary with variations in environmental, climatic, and cultural conditions, as it has not been tested under all possible environmental conditions. The color determination is in accordance with The 2015 Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
