Description

Botanical classification: Heliopsis helianthoides var. scabra.

Varietal denomination: ‘BullHeliopsisscabra 01’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Heliopsis plant, known by the varietal name ‘BullHeliopsisscabra 01’. The new variety was discovered in August of 2020 in Gönnebek, Germany as the result of a planned breeding program with the purposes of providing compact Heliopsis plants with different flower colors, good growth habit, improved uniformity, good branching, good propagation rates, and that perform well. The new variety is the result of a cross between an unpatented Heliopsis variety having an internal breeder's reference of “BulHs 2018-03” (female parent) and an unpatented Heliopsis variety having an internal breeder's reference of “BulHs-2018-11” (male parent) from the breeder's own collection. The new variety was first asexually reproduced via in-vitro tissue culture cuttings in Gönnebek, Germany in September of 2020. The new variety is similar to its parental varieties in botanical classification, but exhibits more compactness, a greater number of flowers, specifically yellow-orange flowers, with good self-branching, more branches, and dark-green small leaves than the parental varieties.

When ‘BullHeliopsisscabra 01’ is compared to Heliopsis variety named ‘Hohlspiegel’ (unpatented), ‘BullHeliopsisscabra 01’ is similar to ‘Hohlspiegel’ in botanical classification and the presence of orange-yellow flowers, but ‘BullHeliopsisscabra 01’ exhibits greater compactness, a greater branching habit that is very even, a greater number of flowers, including pure orange flowers, and nicer, cleaner leaves having a green color, no necroses in the leaves or at the edges of the leaves, no brown spots in the middle of the leaves, that distinguish it from ‘Hohlspiegel’. Further, the following characteristics distinguish ‘BullHeliopsisscabra 01’ when generally compared to other Heliopsis varieties known to the breeder:

    • Much more compact;
    • Good self-branching habit;
    • A great number of yellow-orange flowers;
    • Small leaves;
    • Very uniform growth;
    • Nice dark green leaves;
    • Fast crop time;
    • Long-lasting flowers; and
    • Good hardiness as a perennial.
      The new variety has been trial and field tested and has been found to retain its distinctive characteristics and remain true to type through successive asexual propagations. The present invention has not been evaluated under all possible environmental conditions. The phenotype may vary with variations in environment without a change in the genotype of the plant.

DESCRIPTION OF THE DRAWINGS

The accompanying photographic drawings illustrate the new variety at 20 weeks of age, with the color being as nearly true as is possible with color illustrations of this type:

FIG. 1 shows an entire plant of the new variety.

 DESCRIPTION OF THE PLANT

The following detailed description sets forth the characteristics of the new variety as the result of asexual reproductions performed via in vitro tissue culture cuttings carried out in Gönnebek, Germany. Plants of the new variety were grown outdoors in 15 cm (1.5 liter) pots under normal field production conditions (2 pinches), and the color readings and measurements were observed outdoors under natural light on 20-week-old plants in Gönnebek, Germany. Color references are primarily to The 2015 R.H.S. Colour Chart of The Royal Horticultural Society of London, Sixth Edition, except where terms of ordinary significance are used.
