Abstract

A new and distinct variety of Poinsettia plant named ‘Windark’, characterized by its dark red, reflexed flower bracts; dark green, reflexed leaves; freely branching plant habit; relatively strong stems in comparison to other selections with reflexed bracts and leaves; 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 ‘Windark’.
The new variety is a naturally-occurring branch mutation of the Inventor's proprietary Euphorbia pulcherrima Willd. seedling selection code number P-60. The new Poinsettia was selected by the Inventor in a greenhouse in Encinitas, Calif., in the winter of 1995. 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 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 ‘Windark’. These characteristics in combination distinguish ‘Windark’ as a new and distinct variety:
1. Dark red, reflexed flower bracts.
2. Dark green, reflexed leaves.
3. Freely branching plant habit.
4. Relatively strong stems compared to other sections with reflexed bracts and leaves.
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 the seedling selection P-60 in the following characteristics:
1. Plants of the new Poinsettia are more compact than plants of P-60.
2. Primary flower bracts of plants of the new Poinsettia are smaller than primary flower bracts of plants of P-60.
3. Plants of the new Poinsettia are more freely branching than plants of P-60.
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 in colored reproductions of this type. The photograph comprises a side perspective view of a typical plant of ‘Windark’.
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 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 long nyctoperiods.
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.
