Botanical classification/cultivar designation: Verbena hybrida cultivar Kieverstar SC.BACKGROUND OF THE INVENTION
The present Invention relates to a new and distinct cultivar of Verbena plant, botanically known as Verbena hybrida, and hereinafter referred to by the name ‘Kieverstar SC’.
The new Verbena was discovered by the Inventor in 1999 as a naturally-occurring whole plant mutation of an unnamed Verbena hybrida seedling selection, not patented, in a greenhouse in Venhuizen, The Netherlands. The new Verbena was selected by the Inventor on the basis of its unique flower color and compact growth habit.
Asexual reproduction of the new cultivar by terminal cuttings taken in a controlled environment in Venhuizen, The Netherlands, since 1999, has shown that the unique features of this new Verbena are stable and reproduced true to type in successive generations of asexual reproduction.SUMMARY OF THE INVENTION
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Kieverstar SC’. These characteristics in combination distinguish ‘Kieverstar SC’ as a new and distinct cultivar:
1. Compact, upright, somewhat outwardly spreading, and mounded plant habit.
2. Freely branching habit; dense and bushy growth habit.
3. Dark green-colored leaves.
4. Red purple and light pink bi-colored flowers.
Plants of the new Verbena differ primarily from plants of the mutation parent in flower color as plants of the unnamed selection had solid purple-colored flowers.
Plants of the new Verbena can be compared to plants of the cultivar Kieverbviviole, not patented. In side-by-side comparisons conducted in Venhuizen, The Netherlands, plants of the new Verbena differed primarily from plants of the cultivar Kieverbviviole in flower coloration as plants of the cultivar Kieverbviviole had light purple and violet bi-colored flowers.BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying colored photographs illustrate the overall appearance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Verbena.
The photograph at the top of the sheet comprises a side perspective view of a typical flowering plant of ‘Kieverstar SC’ grown in a container.
The photograph at the bottom of the sheet comprises a close-up view of typical inflorescences and leaves of ‘Kieverstar SC’.DETAILED BOTANICAL DESCRIPTION
The cultivar Kieverstar SC has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity without, however, any variance in genotype. The aforementioned photographs and following observations and measurements describe plants grown in Lompoc, Calif., under commercial practice during the winter and spring in a polycarbonate-covered greenhouse with day temperatures about 18 to 24° C., night temperatures about 16 to 18° C., and light levels about 4,000 to 8,000 foot-candles. Cuttings were planted in 12.7-cm containers, pinched one time, and grown for about 13 weeks. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
