Description

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Poinsettia plant, botanically known as Eurphorbia pulcherrima Willd., and hereinafter referred to by the name ‘Eckaddie’.

The new Poinsettia is a product of a mutation induction breeding program conducted by the Inventor in Encinitas, Calif. The objective of the Inventor's Poinsettia development program is to create new Poinsettia cultivars having interesting bract and leaf display, desirable bract and foliage color and form, strong and freely branching stems and good post-production longevity.

The new Poinsettia originated by exposing unrooted cuttings of the Euphorbia pulcherrima Willd. cultivar Red Splendor, disclosed in U.S. Plant Pat. No. 9,632, to gamma-ray radiation at a level of 3,000 rads. The new Poinsettia was discovered and selected by the Inventor in December, 1997. The selection of this plant was based on its unique bright red and pink-flecked bract color.

Asexual reproduction of the new Poinsettia by terminal cuttings taken at Encinitas, 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 ‘Eckaddie’. These characteristics in combination distinguish ‘Eckaddie’ as a new and distinct cultivar:

1. Bright red bracts with random pink flecks.

2. Response time about 10 weeks.

3. Very dark green leaves which provide an excellent contrast to the bright red and pink-flecked bracts.

4. Compact, dense and upright plant habit; rounded canopy.

5. Very freely branching habit.

6. Excellent postproduction longevity.

In side-by-side comparisons conducted in Encinitas, Calif., plants of the new Poinsettia and the parent cultivar Red Splendor differ primarily in bract coloration as Red Splendor has solid bright red-colored bracts. In addition, plants of the new Poinsettia are more compact and flower about 4 or 5 days later than plants of ‘Red Splendor’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Poinsettia, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type.

The photograph at the top of the first sheet comprises a side perspective view of a typical plant of ‘Eckaddie’.

The photograph at the bottom top of the first sheet comprises a top perspective view of a typical plant of ‘Eckaddie’.

The photograph on the second sheet is a close-up view of typical bracts and leaves of ‘Eckaddie’ (left) and ‘Red Splendor’ (right). Bract and foliage colors in the photographs may differ from actual colors due to light reflectance.

DETAILED BOTANICAL DESCRIPTION

The new Poinsettia 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 observations and measurements describe plants grown in Encinitas, Calif., under commercial practice in a glass-covered greenhouse with day temperatures ranging from 21 to 27° C., night temperatures ranging from 18 to 20° C., and light levels about 4,000 foot-candles. Plants were grown in 16-cm pots, pinched one time, and flowered under naturally lengthening nyctoperiods during the fall/early winter.

In the following description, color references are made to The Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used.
