ABSTRACT:
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 name ‘Jacaimee’.
The new Poinsettia a product of a planned breeding program conducted by the Inventor in Skibby, Denmark. The objective of the breeding program is to create new Poinsettia cultivars having flower bracts with desirable colors, uniform plant habit and excellent post-production longevity.
The new Poinsettia is an induced mutation of the Poinsettia cultivar Pepride, disclosed in U.S. Plant Pat. No. 10,183. Plants of the new Poinsettia originated by exposing unrooted cuttings of the Poinsettia cultivar Pepride to X-ray radiation. The new Poinsettia was discovered and selected by the Inventor as a single flowering plant within a population of irradiated plants in a controlled environment in Skibby, Denmark, in 1998. The selection of this plant was based on its attractive flower bract colors and good plant form and substance.
Asexual reproduction of the new Poinsettia by terminal cuttings taken at Encinitas, Calif., since 1999, 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 ‘Jacaimee’. These characteristics in combination distinguish ‘Jacaimee’ as a new and distinct cultivar:
1. Inflorescences with creamy white-colored flower bracts.
2. Dark green-colored leaves with green-colored petioles.
3. Compact, uniform and upright plant habit.
4. Freely branching habit.
5. Early flowering, natural season flower maturity date is November 15 for plants grown in Encinitas, Calif.; response time, about 7.5 weeks.
6. Excellent post-production longevity.
Plants of the new Poinsettia can be compared to plants of the mutation parent, the cultivar Pepride. In side-by-side comparisons conducted in Encinitas, Calif., plants of the new Poinsettia differed from plants of the cultivar Pepride in the following characteristics:
1. Plants of the new Poinsettia are more compact and not as vigorous as plants of the cultivar Pepride.
2. Flower bract color of plants of the new Poinsettia is cream white whereas flower bract color of plants of the cultivar Pepride is red.
