Abstract

A new and distinct variety of Poinsettia plant named `Eckadonis`, characterized by its bright red flower bracts; dark green leaves; compact palnt habit; freely branching habit; and excellent postproduction longevity.

Description

BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct variety of Poinsettia plant, botanically known as Euphorbia pulcherrima Willd., and hereinafter referred to by the name `Eckadonis`.
The new variety is a naturally-occurring branch mutation of the commerical Euphorbia pulcherrima Willd. cultivar `Red Sails`, disclosed in U.S. Plant Pat. No. 6,980. The new Poinsettia was selected by the Inventor in a greenhouse in Encinitas, Calif., in 1996. 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.
Asexual reproduction of the new variety by terminal cuttings taken at Encinitas, Calif., has shown that the unique features of this new Popinsettia are stable and reproduced true to type in successive generations of asexual reproduction.
BRIEF SUMMARY OF THE INVENTION
The followiong traits have been repeatedly obsrerved and are determined to be the unique characteristics of `Eckadonis`. These charaacteristics in combination distinguish `Eckadonis` as a new distinct variety:
1. Bright red flower bracts.
2. Dark green leaves.
3. Compact plant habit.
4. 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 Sails` in the following characteristics:
1. Plants of the new Poinsettia are more compact, less vigorous and less open than plants of `Red Sails`.
2. Flower bracts of plants of the new Poinsettia are brighter red in color than flower bracts of plants of `Red Sails`.
4. Plants of the new Poinsettia flower later than plants of the cultivar `Red Sails`.
BRIEF DESCRIPTION OF THE PHOTOGRAPH
The accompanying colored photograph illustrates the overall appearance of the new variety, showing the colors as true as it is reasonably possible to obtain a colored reproduction of this type. The photograph comprises a side perspective view of a typical plant of `Eckadonis`.
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 intrensity, 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 23° C, night temperatures about 17° 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 Horiotcultural Society Colour Chart except where general terms of ordinary dictionary significance are used.
