Description

Botanical classification: Rudbeckia hirta L.

Varietal denomination: ‘BullRudihir 119’.

BACKGROUND OF THE INVENTION

The present invention comprises a new and distinct cultivar of Rudbeckia plant known by the varietal name ‘BullRudihir 119’. The new variety was discovered in August of 2021 in Gönnebek, Germany as the result of a planned breeding program with the purposes of providing Rudbeckia plants with improved growth, more uniformity, a compact growth habit, increased branching, attractive foliage, large inflorescences, unique inflorescence colors, and bicolored inflorescences. The new variety is the result of a cross between an unpatented Rudbeckia hirta L. variety having an internal breeder's reference of “BR 16-2020” (female parent) and an unpatented Rudbeckia hirta L. variety having an internal breeder's reference of “BR 26-2020” (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 2021. The new variety is similar to its parental varieties in botanical classification, but exhibits bigger inflorescences, increased branching, and more attractive foliage than both of its parental varieties. Further, ‘BullRudihir 119’ exhibits bicolored inflorescences with a different colored inflorescence center than its female parent and earlier flowering with a more compact growth habit that distinguishes it from its male parent.

When ‘BullRudihir 119’ is compared to Rudbeckia hirta L. variety named ‘Denver Daisy’ (unpatented), ‘BullRudihir 119’ is similar to ‘Denver Daisy’ in botanical classification, but ‘BullRudihir 119’ exhibits larger, bicolored inflorescences that are more yellow/reddish brown, more uniform growth with increased self-branching, and more attractive foliage than ‘Denver Daisy’. Further, the following characteristics distinguish ‘BullRudihir 119’ when generally compared to other Rudbeckia varieties known to the breeder:

    • Large, yellow/reddish brown bicolored inflorescences with a brown center;
    • Good self-branching;
    • An upright, compact, and uniform growth habit;
    • Healthy, green foliage;
    • Long bloom time; and
    • Ease of growth.
      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 DRAWING

The accompanying photographic drawing illustrates the new variety at 17 weeks of age, with the color being as nearly true as is possible with color illustrations of this type.

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 21 cm (4 liter) pots under normal field production conditions. The color readings and measurements were observed outdoors under natural light on 17 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.
