Description

Botanical classification: Rudbeckia hirta L.

Varietal denomination: ‘BullRudi 14’.

BACKGROUND OF THE INVENTION

The present invention comprises a new and distinct cultivar of Rudbeckia plant known by the varietal name ‘BullRudi 14’. The new variety was discovered in August of 2017 in Gönnebeck, 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, better branching, attractive foliage, large blooms, and unique flower colors. The new variety is the result of a cross between an unpatented Rudbeckia hirta L. variety having an internal breeder's reference of “BR273-2014” (female parent) and an unpatented Rudbeckia hirta L. variety having an internal breeder's reference of “BR83-2013” (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 2017. The new variety is similar to its parental varieties in botanical classification, but exhibits larger flowers, increased branching, and more attractive foliage than both of its parental varieties. Further, its compact growth habit and brown flower center distinguish ‘BullRudi 14’ from its male parent.

When ‘BullRudi 14’ is compared to Rudbeckia hirta L. variety named ‘Prairie Sun’ (unpatented), ‘BullRudi 14’ is similar to ‘Prairie Sun’ in botanical classification, but ‘BullRudi 14’ exhibits improved plant quality, more uniform growth with increased self-branching, more attractive foliage, and large, yellow-orange flowers with a brown center that distinguish it from ‘Prairie Sun’. Further, the following characteristics distinguish ‘BullRudi 14’ when generally compared to other Rudbeckia varieties known to the breeder:

    • Large, yellow-orange blooms with a brown center;
    • Good self-branching;
    • An upright, compact, and uniform growth habit;
    • Healthy, green foliage;
    • Long bloom time;
    • Ease of growth; and
    • Unique flower color combination.

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 18 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; and

FIG. 2 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 Gönnebeck, Germany. Plants of the new variety were grown outdoors in 21 cm (4 liter) pots under normal field production conditions, and the color readings and measurements were observed outdoors under natural light on 18 week old plants in Gönnebeck, 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.
