Description

Botanical denomination: Heliopsis helianthoides (L.) Sweet. Variety designation: ‘Sundial’. STATEMENT REGARDING PRIOR DISCLOSURES UNDER 37 CFR 1.77(B)(6) The first offer for sale of Heliopsis ‘Sundial’ was by Walters Gardens, Inc. to North Coast Perennials and North Branch Nursery on Oct. 15, 2024. The new plant was also first listed on Dec. 1, 2024, with a brief description and photograph on a website managed by Walters Gardens, Inc. and in their “Walters Gardens 2025-2026 Catalog” released on Jun. 3, 2025. Walters Gardens, Inc. obtained the new plant and all information relating thereto directly from the inventor. No plants of Heliopsis ‘Sundial’ have been sold, in this country or anywhere in the world, by any name, nor has any disclosure of the new plant been made more than one year prior to the filing date of this application, and such sale or disclosure within one year was either derived directly or indirectly from the inventor and would be a 35 U.S.C. § 102(b) exception. BACKGROUND AND ORIGIN OF THE PLANT The present invention relates to a new and distinct cultivar of Heliopsis ‘Sundial’. The new plant was selected as a single seedling from the cross performed at a wholesale nursery in Zeeland, Michigan on Aug. 1, 2020, by the inventor between ‘Fire Twister’ U.S. Plant Pat. No. 25,524 as the female or seed parent and a proprietary unnamed hybrid known only by the breeder code 17-3-1 (not patented) as the male or pollen parent. Seed was harvested on Nov. 4, 2020, and eventually the single seedling was assigned the breeder code 20-7-xxx toward the end of the trial period. The new plant was approved in an initial evaluation in the summer of 2022 and slated for further trials and later introduction. The new plant was selected based on its compact habit, strong stems, ability to withstand lodging, mildew resistance, attractive colorful foliage, high-quality flowers over a long period, and ability to attract pollinators. The new plant has been asexually first propagated by division at the same nursery in the summer of 2022 and later by shoot tip cuttings with the resultant asexually propagated plants remaining identical to the original plant, stable and true to type in successive generations. SUMMARY OF THE INVENTION Plants of the new False Sunflower have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions comprising temperature, daylength, light intensity, and fertility, without, however, any variations in genotype. The following traits have been repeatedly observed and are determined to be the unique characteristics of the new Heliopsis plant. These characteristics in combination distinguish ‘Sundial’ as a new and distinct Heliopsis plant: 1. Lanceolate to ovate, dark green foliage with burgundy highlighted margins;2. Tall rounded plant habit with extensive branching habit;3. Very floriferous and freely flowering habit beginning in early July and continuing for about six to eight weeks;4. Single to semi-double inflorescences with overlapping ray florets;5. Ray florets open with a burnt orangish-red eye and lighten to a golden yellow;6. Strong garden performance and excellent for cut flowers. The female parent, ‘Fire Twister’, has darker burgundy foliage and a larger inflorescence with red-orange ray florets that lighten with maturity. The male parent has a shorter habit with smaller, single, yellow ray florets with improved basal branching. The following cultivars are the most similar cultivars known to the inventor: ‘Luna Rojo’ U.S. Plant Pat. No. 34,988, ‘Bleeding Hearts’ (not patented), ‘Forged in Fire’ U.S. Plant patent application Ser. No. 18/831,787, and ‘Funky Spinner’ U.S. Plant Pat. No. 34,988, (not patented). ‘Luna Rojo’ has a smaller denser habit. ‘Bleeding Hearts’ has a slightly shorter habit and the foliage has more purplish highlights. ‘Forged in Fire’ has a slightly larger more upright habit. ‘Funky Spinner’ has a shorter habit, and inflorescences with ray florets that are more distinctly banded yellow on the outside and reddish-orange in the center. BRIEF DESCRIPTION OF THE DRAWINGS The photographs of the new plant demonstrate the unique traits of Heliopsis ‘Sundial’ and the overall appearance of a three-year-old plant in the full sun display garden of a nursery in Zeeland, Michigan. The colors are as accurate as reasonably possible with color reproductions. Variation in ambient light spectrum, source and direction may cause the appearance of minor variation in color. FIG. 1 shows the landscape habit of the new plant. FIG. 2 shows a close-up of the inflorescences and bud. DETAILED BOTANICAL DESCRIPTION The following descriptions and color references are based on the 2015 edition of The Royal Horticultural Society Colour Chart except where common dictionary terms are used. Heliopsis ‘Sundial’ has not been observed in all possible environments. The phenotype may vary
