ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Rudbeckia plant, botanically known as
Rudbeckia fulgida
var. Sullivantii and referred to by the cultivar name Pot of Gold.
The new cultivar is a product of a planned breeding program conducted by the Inventor in Boisbriand, Quebec, Canada. The objective of the breeding program was to create new compact Rudbeckia cultivars with uniform plant habit, large inflorescences and intense ray floret color.
The new cultivar originated from a self-pollination made by the Inventor of the
Rudbeckia fulgida
var. Sullivantii cultivar Goldstrum, not patented. The new Rudbeckia was selected by the Inventor as a flowering plant within the progeny of this cross in a controlled environment in Boisbriand, Quebec, Canada, in the 1990.
Plants of the new cultivar are different from plants of the parent, the cultivar Goldstrum, in the following characteristics:
1. Plants of the new Rudbeckia are more compact than plants of the cultivar Goldstrum.
2. Plants of the new Rudbeckia are more uniform in plant habit and height than plants of the cultivar Goldstrum.
3. Plants of the new Rudbeckia have larger inflorescences than plants of the cultivar Goldstrum.
4. Ray floret color of the new Rudbeckia is much more intense than ray floret color of the cultivar Goldstrum.
Asexual propagation of the new cultivar by crown divisions and by terminal cuttings at Boisbriand, Quebec, Canada, has shown that the unique features of this new Rudbeckia are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Pot of Gold’. These characteristics in combination distinguish ‘Pot of Gold’ as a new and distinct cultivar:
1. Compact, uniform and mounded plant habit.
2. Freely branching and vigorous.
3. Large leaves.
4. Large inflorescences with intense golden yellow ray florets and dark brown disc florets.
5. Good garden performance and very good resistance to drought conditions.
The cultivar Pot of Gold has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength and light intensity, without, however, any variance in genotype.
