Description

Botanical classification: Rudbeckia hirta.

Varietal denomination: ‘Lion Cub’.

BACKGROUND OF THE NEW PLANT

The present invention is a new and distinct Rudbeckia plant having the varietal name ‘Lion Cub’. Rudbeckia is in the family Asteraceae. ‘Lion Cub’ is a selection from a planned breeding program that originated from a controlled cross between unnamed, unpatented, and proprietary Rudbeckia hirta seedlings. The seed parent has a small habit with semi-double, yellow-orange flowers. The pollen parent has a medium habit with semi-double, gold flowers.

Compared to the annual Rudbeckia plant named ‘Maya’ (unpatented), the new cultivar is more gold colored than yellow and is more consistent in height and flower form. Compared to Rudbeckia plant named ‘Henry Eilers’ (unpatented), ‘Lion Cub’ is an annual, not a perennial, has fully double flowers and is much shorter than ‘Henry Eilers’.

The new variety has only been reproduced by asexual propagation (cuttings and tissue culture). Each of the progeny exhibits identical characteristics to the original plant. Asexual propagation by cuttings and tissue culture using standard micropropagation techniques with terminal and lateral shoots performed in Canby, Oregon shows that the characteristics and distinctions described herein come true to form and are established and transmitted through succeeding 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.

When compared to other Rudbeckia plants known to the breeder, the new variety is characterized by the following:

    • 1. Inflorescences with cupped to quilled, golden-colored ray florets;
    • 2. A short, rounded habit; and
    • 3. Excellent vigor.

DESCRIPTION OF THE DRAWINGS

The accompanying photographic drawings illustrate the new variety at approximately 6 months of age, with the colors being as nearly true as possible with color illustrations of this type:

FIG. 1 illustrates a close-up view of the new variety in Canby, Oregon; and

FIG. 2 illustrates plants of the new variety in the field in full sun in Canby, Oregon in early October.
