Latest Paul Ecke Ranch, Inc. Patents:
The present invention relates to a new and disticnt variety of Poinsettia plant, botanically known as Euphorbia pulcherrima Willd., and hereinafter referred to by the name `Eckadali`.
The new variety is a spontaneous branch mutation of the commercial Euphorbia pulcherrima Willd. cultivar `Red Splendor`, disclosed in U.S. Plant Pat. No. 9,632. The new Poinsettia was selected by the Inventor in a greenhouse in Nipomo, Calif., in 1997. The objective of the Inventor's Poinsettia development program is to create new Poinsettia cultivars having desirable bract and foliage color and form, strong and freely branching stems and good post-production longevity.
Asexual reproduction of the new variety 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 INVENTIONThe following traits have been repeatedly observed and are determined to be the unique characteristics of `Eckadali`. These characteristics in combination distinguish `Eckadali` as a new and distinct variety:
1. Creamy white flower bracts.
2. Extremely dark green leaves.
3. Compact plant habit.
4. Very freely branching habit.
5. Excellent postproduction longevity.
In side-by-side comparisons conducted by the Inventor in Encinitas, Calif., plants of the new Poinsettia differed from plants of `Red Splendor` in the following characteristics:
1. Plants of the new Poinsettia have white-colored flower bracts whereas plants of the cultivar `Red Splendor` have red-colored flower bracts.
2. Plants of the new Poinsettia are more compact than plants of the cultivar `Red Splendor`.
3. Inflorescences of plants of the new Poinsettia are smaller than inflorescences of plants of `Red Splendor`.
BRIEF DESCRIPTION OF THE PHOTOGRAPHThe accompanying colored photograph illustrates the overall appearance of the new variety, showing the colors as true as it is reasonably possible to obtain in a colored reproduction of this type. The photograph comprises a side perspective view of a typical plant of `Eckadali`.
DETAILED BOTANICAL DESCRIPTIONThe 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 polyethylene-covered greenhouse with day temperatures about 22 to 24.degree. C., night temperatures about 16 to 18.degree. C. and light levels about 40,000 lux. Plants were grown in 16.5--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.
