ABSTRACT:
Botanical classification/cultivar denomination:
Euphorbia pulcherrima
Willd. cultivar Festival Pink.
BACKGROUND OF THE INVENTION
The present Invention relates to a new and distinct cultivar of Poinsettia plant, botanically known as
Euphorbia pulcherrima
Willd., and hereinafter referred to by the cultivar name ‘Festival Pink’.
The new Poinsettia is a product of a planned breeding program conducted by the Inventor in Lompoc, Calif. The objective of the breeding program is to create new Poinsettia cultivars with uniform plant habit and attractive flower bract coloration.
The new Poinsettia is a induced mutation of the
Euphorbia pulcherrima
Willd. cultivar Festival Red, disclosed in U.S. Plant Pat. No. 10,253. The new Poinsettia was discovered and selected by the Inventor as a single plant within a population of irradiated plants of the cultivar Festival Pink in a controlled environment in Lompoc, Calif. The selection of this plant was based on its attractive flower bract coloration and uniform plant habit.
Asexual reproduction of the new Poinsettia by vegetative terminal cuttings taken at Lompoc, Calif., has shown that the unique features of this new Poinsettia are stable and reproduced true to type in successive generations of asexual reproduction.
BRIEF SUMMARY OF THE INVENTION
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Festival Pink’. These characteristics in combination distinguish ‘Festival Pink’ as a new and distinct Poinsettia cultivar:
1. Uniform plant growth habit.
2. Dark green-colored leaves.
3. Early flowering habit.
4. Inflorescences with dark pink-colored flower bracts that resist fading.
5. Excellent post-production longevity.
Plants of the new Poinsettia differ primarily from plants of the parent cultivar in flower bract coloration as plants of the cultivar Festival Red have red-colored flower bracts.
Plants of the new Poinsettia can be compared to plants of the cultivar 490 Pink, disclosed in U.S. Plant Pat. No. 8,817. In side-by-side comparisons conducted in Lompoc, Calif., plants of the new Poinsettia differed from plants of the cultivar 490 Pink in the following characteristics:
1. Plants of the new Poinsettia were shorter than plants of the cultivar 490 Pink.
2. Plants of the new Poinsettia were more upright and not as outwardly spreading as plants of the cultivar 490 Pink.
3. Plants of the new Poinsettia had thicker lateral branches than plants of the cultivar 490 Pink.
4. Plants of the new Poinsettia had oblong-shaped flower bracts whereas plants of the cultivar 490 Pink had ovate-shaped flower bracts.
5. Flower bract color of plants of the new Poinsettia was darker pink than flower bract color of plants of the cultivar 490 Pink.
6. Plants of the new Poinsettia had tighter cyathia clusters than plants of the cultivar 490 Pink.
