Description

BOTANICAL CLASSIFICATION/CULTIVAR DESIGNATION

Calibrachoa procumbens cultivar Kiecadros.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Calibrachoa plant, botanically known as Calibrachoa procumbens, and hereinafter referred to by the cultivar name Kiecadros.

The new Calibrachoa is a product of a planned breeding program conducted by the Inventor in Venhuizen, The Netherlands. The objective of the breeding program is to create new Calibrachoas with numerous flowers with attractive flower colors.

The new Calibrachoa originated from a cross made by the Inventor during the summer of 1999 of a proprietary Calibrachoa selection identified as KA-1790, not patented, as the female, or seed parent, with a proprietary Calibrachoa selection identified as KA-11-1277, not patented, as the male, or pollen parent. The new Calibrachoa was selected as a single flowering plant from the resulting progeny by the Inventor in 1999 in Venhuizen, The Netherlands.

Asexual reproduction of the new cultivar by terminal cuttings taken in Venhuizen, The Netherlands since 1999 has shown that the unique features of this new Calibrachoa are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the cultivar Kiecadros have 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 following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Kiecadros’. These characteristics in combination distinguish ‘Kiecadros’ as a new and distinct cultivar:

1. Uniform, low-growing, cascading and outwardly spreading plant habit.

2. Freely and continuous branching habit; short internodes; dense and bushy plant growth habit.

3. Small leaves.

4. Freely flowering habit, numerous red purple-colored flowers.

Plants of the new Calibrachoa differ from the female parent, the selection KA-1790, in flower size and flower color as plants of the female parent have smaller flowers and less intense red purple-colored flowers. Plants of the new Calibrachoa differ from the male parent, the selection KA-11-1277, primarily in flower color as plants of the male parent have bright red purple-colored flowers with distinct venation.

Plants of the new Calibrachoa can be compared to plants of the Calibrachoa cultivar Carillon Cherry Rose, not patented. In side-by-side comparisons conducted in Venhuizen, The Netherlands, plants of the new Calibrachoa differed from plants of the cultivar Carillon Cherry Rose in the following characteristics:

1. Plants of the new Calibrachoa flowered earlier than plants of the cultivar Carillon Cherry Rose.

2. Plants of the new Calibrachoa had larger flowers than plants of the cultivar Carillon Cherry Rose.

3. Plants of the new Calibrachoa had darker and more intense red purple-colored flowers than plants of the cultivar Carillon Cherry Rose.

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 photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Calibrachoa.

The photograph at the top of the sheet comprises a side perspective view of a typical flowering plant of ‘Kiecadros’ grown in a container.

The photograph at the bottom of the sheet comprises a close-up view of typical developing flower buds and flowers, lower surface of an opened flower, and upper and lower of typical leaves of ‘Kiecadros’.

DETAILED BOTANICAL DESCRIPTION

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. One cutting was planted per 15-cm container and plants were grown for about 12 weeks. In the following description, color references are made to The Royal Hortidultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
