USPP29818P2 - Coreopsis plant named ‘Red Tapestry’ - Google Patents

Abstract

A new cultivar of hybrid Coreopsis named ‘Red Tapestry’ that is characterized by its sturdy, well-branched plant habit reaching an average of 40 cm in height and 65 cm in width, floriferous and long blooming season of sterile inflorescences that do not require deadheading; bloom commences in early July and lasts until frost in Kensington, Conn., its medium sized inflorescences with ray florets that are dark yellow in color with red eye zones in color, its resistance to powdery mildew and leafspot, and its cold hardiness at least to U.S.D.A. Zone 5.

Description

Botanical classification: Coreopsis hybrid.

Variety denomination: ‘Red Tapestry’.

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 ‘Red Tapestry’ and will be referred to hereinafter by its cultivar name, ‘Red Tapestry’. 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 plant from his breeding program, ref. no. J 06-1, as the female parent and pollen that was pooled from a variety of unnamed plants from his breeding program as the male parent. The exact characteristics of the pollen parent are therefore unknown. ‘Red Tapestry’ 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 cutting 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 ‘Red Tapestry’ as a unique cultivar of Coreopsis.

• • 1. ‘Red Tapestry’ exhibits a sturdy, well-branched plant habit reaching an average of 40 cm in height and 65 cm in width.
  • 2. ‘Red Tapestry’ exhibits a floriferous and long blooming season of sterile inflorescences that do not require deadheading; bloom commences in early July and lasts until frost in Kensington, Conn.
  • 3. ‘Red Tapestry’ exhibits medium sized inflorescences with ray florets that are dark yellow in color with red eye zones.
  • 4. ‘Red Tapestry’ exhibits resistance to powdery mildew and leafspot.
  • 5. ‘Red Tapestry’ exhibits cold hardiness at least to U.S.D.A. Zone 5.

The female parent of ‘Red Tapestry’, ref. no. J 06-1, differs from ‘Red Tapestry’ in having a taller plant height, a floppy plant habit and inflorescences with bright yellow ray florets. ‘Red Tapestry’ can be most closely compared to Coreopsis cultivars ‘Red Chiffon’ (U.S. Plant Pat. No. 27,528) and ‘Lightning Bug’ (U.S. Plant Pat. No. 27,361). ‘Red Chiffon’ is similar to ‘Red Tapestry’ in being from a closely related breeding line, in having thread-leaf type foliage and in having similar inflorescence shape and cold hardiness. ‘Red Chiffon’ differs from ‘Red Tapestry’ in having inflorescences that are light yellow in color with red eyezones. ‘Lightning Bug’ is similar to ‘Red Tapestry’ in having inflorescences of similar size and color and in having thread-like foliage. ‘Lightning Bug’ differs from ‘Red Tapestry’ in having inflorescence with ray florets that are paler yellow in color, in being prone to powdery mildew, and in being less cold hardy.

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 5 month-old plant of ‘Red Tapestry’ 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 ‘Red Tapestry’ and shows the plant habit in bloom.

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

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.
