ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Marguerite Daisy plant, botanically known as
Argyranthemum frutescens
and referred to by the cultivar name ‘Summer Stars Pink’.
The new cultivar is a product of a planned breeding program conducted by the Inventor in Cobbitty, New South Wales, Australia. The objective of the breeding program was to develop compact, freely-flowering Marguerite daisies good inflorescence form and floret color.
The new cultivar originated from a cross made by the Inventor in September, 1995, of a proprietary selection of
Argyranthemum frutescens
identified as number X943817.2, as the male or pollen parent, with a proprietary selection of
Argyranthemum frutescens
identified as number X931909.1, as the female or seed parent. The cultivar ‘Summer Stars Pink’ was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross in a controlled environment in Glenfield, New South Wales, Australia.
Plants of the new Marguerite Daisy are paler pink in ray floret color, have finer foliage and flower earlier than plants of the male parent, the selection number X943817.2.
Plants of the new Marguerite Daisy are darker pink in ray floret color and differ in inflorescence form compared to plants of the female parent, the selection number X931909.1.
Asexual reproduction of the new cultivar by terminal cuttings in Cobbitty, New South Wales, Australia, has shown that the unique features of this new Marguerite Daisy are stable and are reproduced true to type in successive propagations.
SUMMARY OF THE INVENTION
The new cultivar 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.
The following characteristics have been repeatedly observed and are determined to be basic characteristics of ‘Summer Stars Pink’ which distinguish ‘Summer Stars Pink’ as a new and distinct cultivar:
1. Upright and mounding plant habit.
2. Dark green fine foliage.
3. Freely branching growth habit.
4. Freely flowering with numerous inflorescences per plant; inflorescences held above the foliage.
5. Long-lasting double-type inflorescences with pink ray florets and yellow-tipped disc florets giving a yellow “eye” to the inflorescence.
Plants of the new Marguerite Daisy can be compared to plants of the cultivar ‘Summer Melody’, disclosed in U.S. Plant Patent Application Ser. No. 09/257,093. In side-by-side comparisons conducted in Encinitas, Calif., plants of the new Marguerite Daisy differ from plants of the cultivar ‘Summer Melody’ in the following characteristics:
1. Plants of the new cultivar are more vigorous, are taller and have a more open plant habit than plants of the cultivar ‘Summer Melody’.
2. Plants of the new cultivar are more freely branching, have longer lateral branches and longer internodes than plants of the cultivar ‘Summer Melody’.
3. Plants of the new cultivar have larger and slightly darker green leaves than plants of the cultivar ‘Summer Melody’.
4. Plants of the new cultivar have more and larger inflorescences than plants of the cultivar ‘Summer Melody’.
5. Inflorescences of plants of the new cultivar have twice as many ray florets than inflorescences of plants of the cultivar ‘Summer Melody’.
6. Inflorescences of plants of the new cultivar are crested in the center and appear taller and more mounding than inflorescences of plants of the cultivar ‘Summer Melody’.
7. Inflorescences of plants of the new cultivar have yellow centers whereas inflorescences of plants of the cultivar ‘Summer Melody’ have purple centers.
