USPP30168P2 - Coreopsis plant named ‘Enchanted Red’ - Google Patents

Abstract

A new cultivar of hybrid Coreopsis named ‘Enchanted Red’ that is characterized by its compact and densely plant habit reaching an average of 23 cm in height and 50 cm in width, its floriferous and long bloom season; bloom commences in late June and continues until frost in Kensington, Conn., its relative sterility under normal garden conditions without the need for deadheading to keep flowering, and its large solid red flowers in warm and cooler temperatures (for the majority of the growing season in New Braintree, Mass.) with new flowers produced during the heat of summer paler red in color.

Description

Botanical classification: Coreopsis hybrid.

Variety denomination: ‘Enchanted Red’.

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 ‘Enchanted Red’ and will be referred to hereinafter by its cultivar name, ‘Enchanted Red’. The new cultivar of Coreopsis is an herbaceous perennial grown for landscape and container use.

The new cultivar was discovered by the Inventor in July of 2015 as a naturally occurring branch mutation of Coreopsis ‘Enchanted Eve’ (U.S. Plant Pat. No. 27,857) in a container in Kensington, Conn.

Asexual propagation of the new cultivar was first accomplished by stem cuttings under the direction of the Inventor in New Braintree, Mass. in July of 2015. Asexual propagation by stem cuttings has determined 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 ‘Enchanted Red’ as a new and distinct cultivar of Coreopsis.

• • 1. ‘Enchanted Red’ exhibits a compact and densely branched plant habit reaching an average of 23 cm in height and 50 cm in width.
  • 2. ‘Enchanted Red’ exhibits a floriferous and long bloom season; blooming commences in late June and continues until frost in Kensington, Conn.
  • 3. ‘Enchanted Red’ is relatively sterile under normal garden conditions and does not require deadheading to keep flowering.
  • 4. ‘Enchanted Red’ exhibits large inflorescences with ray florets that are solid red in color in warm and cooler temperatures (for the majority of the growing season in New Braintree, Mass.) with new flowers produced during the heat of summer paler red in color.

The parent plant of ‘Enchanted Red’, ‘Enchanted Eve’, differs from ‘Enchanted Red’ in having inflorescences with ray florets that are light yellow in color and suffused with red a red eye that expands into the ray floret surface in cooler temperatures. ‘Enchanted Red’ can also be most compared to the Coreopsis cultivars ‘Red Elf’ (U.S. Plant Pat. No. 27,918) and ‘Mercury Rising’ (U.S. Plant Pat. No. 24,689). ‘Red Elf’ is similar to ‘Enchanted Red’ in having a compact plant habit, large red flowers, and a long bloom season without requiring deadheading. ‘Red Elf’ differs from ‘Enchanted Red’ in having inflorescences with ray florets that are deeper red in color that is retained the entire season and in having a narrower and more upright plant habit. ‘Mercury Rising’ is similar to ‘Enchanted Red’ in having red ray florets. ‘Mercury Rising’ differs from ‘Enchanted Red’ in having a larger, more openly branched plant habit.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Coreopsis. The plants in the photographs are three months in age (from a 32-cell plug) as grown outdoors in a one-gallon container in New Braintree, Mass.

The photograph in FIG. 1 provides a top view of ‘Enchanted Red’ in bloom.

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

The colors in the photographs are as close as possible with the digital photography techniques available, the color values cited in the detailed botanical description accurately describe the colors of the new Coreopsis.
