ABSTRACT:
BOTANICAL CLASSIFICATION
Euphorbia pulcherrima.
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 ‘Eckahearn’.
The new Poinsettia a product of a planned breeding program conducted by the Inventor in Encinitas, Calif. 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 a naturally-occurring whole plant mutation of a unnamed proprietary induced mutation, not patented, that originated by exposing unrooted cuttings of the
Euphorbia pulcherrima
Willd. cultivar Eckabish, disclosed in U.S. Plant Pat. No. 11,200, to gamma radiation. The new Poinsettia was discovered and selected by the Inventor as a single plant within a population of plants of the irradiated selection on or about Aug. 19, 1998, in a controlled environment in Encinitas, Calif.
Asexual reproduction of the new Poinsettia by terminal cuttings taken at Encinitas, Calif., since October, 1998, 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 ‘Eckahearn’. These characteristics in combination distinguish ‘Eckahearn’ as a new and distinct cultivar:
1. Inflorescences with bright red-colored flower bracts.
2. Dark green-colored leaves with red-colored petioles.
3. Uniform and mounded plant habit.
4. Early flowering, natural season flower maturity date is November 26 for plants grown in Encinitas, Calif.; response time, about 8.5 weeks.
5. Excellent post-production longevity.
Plants of the new Poinsettia are most similar to plants of the cultivar Eckabish. In side-by-side comparisons conducted in Encinitas, Calif., plants of the new Poinsettia differed primarily from plants of the cultivar Eckabish in the following characteristics:
1. Plants of the new Poinsettia were slightly taller, but not as wide as plants of the cultivar Eckabish.
2. Plants of the new Poinsettia had longer leaves than plants of the cultivar Eckabish.
3. Leaves of plants of the new Poinsettia had red-colored veins on the lower surface whereas leaves of plants of the cultivar Eckabish had green-colored veins on the lower surface.
4. Flower bract color of plants of the new Poinsettia was darker red than flower bract color of plants of the cultivar Eckabish.
