plant named ‘Luna Roja’

Abstract

A new cultivar of Heliopsis plant named ‘Luna Roja’ that is characterized by its dwarf plant size, its strong flowering stems, its foliage that is dark green-purple to green-black in color, its inflorescences with ray florets that are orange-red in color, and its blooming from midsummer to early autumn in The Netherlands.

Description

Botanical classification: Heliopsis helianthoides var. scabra.

Variety denomination: ‘Luna Roja’.

CROSS REFERENCE TO A RELATED APPLICATION

This application claims foreign priority to European plant breeders' rights application filed on Dec. 3, 2021, application No. 2021/3171. The Applicant received the information for the Plant breeders' rights application directly from the Inventor.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Heliopsis plant, botanically known as Heliopsis helianthoides var. scabra ‘Luna Roja’ and will be referred to hereinafter by its cultivar name, ‘Luna Roja’.

The new cultivar was discovered as a chance seedling growing in a trial field by the Inventor in Haarlem, The Netherlands in 2018. The seedling arose from seed collected from open pollinated plants in the field that contained numerous unnamed and unpatented proprietary Heliopsis seedlings from the Inventor's breeding program. The seeds were pooled and parentage of ‘Luna Roja’ is therefore unknown.

Asexual propagation of the new cultivar was first accomplished by stem cuttings under the direction of the Inventor in summer of 2019 in Haarlem, The Netherlands. Asexual propagation by stem cuttings and tissue culture using meristematic tissue 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 ‘Luna Roja’ as a unique cultivar of Heliopsis.

• • 1. ‘Luna Roja’ exhibits a dwarf plant size.
  • 2. ‘Luna Roja’ exhibits strong flowering stems (that do not lodge).
  • 3. ‘Luna Roja’ exhibits foliage that is dark green-purple to green-black in color.
  • 4. ‘Luna Roja’ exhibits inflorescences with ray florets that are orange-red in color.
  • 5. ‘Luna Roja’ exhibits blooms from midsummer to early autumn in The Netherlands.

‘Luna Roja’ can be compared to Heliopsis cultivars ‘Bleeding Hearts’ (not patented), ‘Fire Twister’ (U.S. Plant Pat. No. 25,524) and ‘Tuscan Sun’ (U.S. Plant Pat. No. 18,763). ‘Bleeding Hearts’ and ‘Fire Twister’ are both similar to ‘Luna Roja’ in inflorescence and foliage color. ‘Bleeding Hearts’ and ‘Fire Twister’ both differ from ‘Luna Roja’ in having a much taller plant height. ‘Tuscan Sun’ is similar to ‘Luna Roja’ in having a compact plant habit. ‘Tuscan Sun’ differs from ‘Luna Roja’ in having foliage that is green in color and inflorescences that are smaller in size and yellow in color.

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 that fall within a one-year grace period prior to the filing date. Disclosures include website listings on websites by Growing Colors, Plantipp, Hayloft Plants, Vision Pictures, QVCUK, Baldur-Garten, Viridea, Globe Planter, Hortweek, Groupon, and Nursery Management.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying color photographs illustrate the overall appearance and distinct characteristics of the new Heliopsis. The photographs were taken of a plant 12 months in age as field grown in Haarlem, The Netherlands and placed in a 15-cm container for the photographs in Haarlem, The Netherlands.

The photograph in FIG. 1 provides a side view of a plant of ‘Luna Roja’ in bloom.

The photograph in FIG. 2 provides a close-up view of an inflorescence of ‘Luna Roja’.

The photograph in FIG. 3 provides a close-up view of a leaf of ‘Luna Roja’.

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 Heliopsis.
