Abstract

A new cultivar of hybrid Coreopsis named ‘Mercury Rising’ characterized by its exhibits large inflorescences with ray florets that are solid red in color throughout the growing season with white tips appearing when plants are grown under hot temperatures, its vigorous growth habit with healthy foliage, its low growing plant habit, spreading outward from above ground stems that are well branched, its reliably perennial growth habit and cold hardiness at least in U.S.D.A. Zone 5, and its very good resistance to powdery mildew and leaf spot.

Description

Botanical classification: Coreopsis hybrid.
Variety denomination: ‘Mercury Rising’.
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 ‘Mercury Rising’ and will be referred to hereinafter by its cultivar name, ‘Mercury Rising’. 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 Hubbardston, 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.
The Inventor made a controlled cross in summer of 2008 in his test garden in Hubbardston, Mass. between two unnamed plant from the Inventor's breeding program, the female parent is designated as G4 07-2 and the male parent is designated as Y 07-5. ‘Mercury Rising’ was selected in September 2009 as a single unique plant amongst the resulting seedlings.
Asexual reproduction of the new cultivar was first accomplished by stem cuttings under the direction of the Inventor in Kensington, Conn. in September of 2009. The characteristics of this cultivar have been determined to be 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 ‘Mercury Rising’ as unique from all Coreopsis cultivars and species known to the Inventor.
    • 1. ‘Mercury Rising’ exhibits large inflorescences with ray florets that are solid red in color with white tips appearing when plants are grown under hot temperatures.
    • 2. ‘Mercury Rising’ exhibits a vigorous growth habit with healthy foliage.
    • 3. ‘Mercury Rising’ exhibits a low growing plant habit, spreading outward from above ground stems that are well branched without the need for pinching.
    • 4. ‘Mercury Rising’ exhibits a reliably perennial growth habit.
    • 5. ‘Mercury Rising’ is cold hardy at least to U.S.D.A. Zone 5.
    • 6. ‘Mercury Rising’ is shown very good resistance to powdery mildew and leaf spot.
The female parent differs from ‘Mercury Rising’ in having larger inflorescences that have a ray florets that are white in color with purple markings and in having a more open and less densely branched growth habit. The male parent differs from ‘Mercury Rising’ in being taller in height and in lacking cold hardiness in U.S.D.A. Zone 5. ‘Mercury Rising’ can be compared to Coreopsis cultivars ‘Redshift’ (U.S. Plant Pat. No. 20,412) and ‘Center Stage’ (U.S. Plant Pat. No. 22,707). ‘Redshift’ differs from ‘Mercury Rising’ in having inflorescences that are light yellow in color with a red eye for most of the season (turns more red in cool temperatures in fall) and in having a more upright plant habit. ‘Center Stage’ differs from ‘Mercury Rising’ in having a shorter bloom season, in being less cold hardy, and in being less disease resistant.
BRIEF DESCRIPTION OF THE DRAWING
The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Coreopsis.
The photographs in FIG. 1 and FIG. 2 were taken of a plant of ‘Mercury Rising’ about one year in age as grown in a two-gallon container in a greenhouse in Mount Vernon, Wash. The photograph in FIG. 3 was taken of 4-week old plants as growing in 72-cell liners in Pace, Fla.
The photograph in FIG. 1 provides a view of the habit of ‘Mercury Rising’ in bloom.
The photograph in FIG. 2 provides a close-up view of inflorescences of ‘Mercury Rising’.
The photograph in FIG. 3 provides a view of inflorescences of ‘Mercury Rising’ as grown under hot temperatures. The colors in the photograph may differ slightly from the color values cited in the detailed botanical description, which accurately describe the colors of the new Coreopsis.
DETAILED BOTANICAL DESCRIPTION
The following is a detailed description of the new cultivar as observed for three years in a test garden in Hubbardston, Mass. with the detailed botanical data collected from six month-old plants of the new cultivar as grown in one-gallon containers in Kensington, Conn.
