Description
BOTANICAL CLASSIFICATION/CULTIVAR DESIGNATION

Zantedeschia aethiopica cultivar Red Desire.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Zantedeschia plant, botanically known as Zantedeschia aethiopica, and hereinafter referred to by the name ‘Red Desire’.

The new Zantedeschia is a product of a planned breeding program conducted by the Inventor in Steenbergen, The Netherlands. The objective of the program is to create and develop new freely flowering Zantedeschia cultivars with attractive spathe color that can be used as a cut flower as well as a container plant.

The new Zantedeschia originated from a cross-pollination by the Inventor in 1995 of a Zantedeschia aethiopica selection identified as white, not patented, as the female, or seed, parent with the Zantedeschia aethiopica cultivar Marsh Mellow, not patented, as the male, or pollen, parent. The cultivar Red Desire was discovered and selected by the Inventor as a plant within the progeny of the stated cross-pollination in a controlled environment in Steenbergen, The Netherlands.

Asexual propagation of the new cultivar by rhizome divisions in Steenbergen, The Netherlands since 1997 has shown that the unique features of this new Zantedeschia plant are stable and reproduced true to type in successive generations of asexual propagation.

BRIEF SUMMARY OF THE INVENTION

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

1. Upright and somewhat outwardly spreading plant habit.

2. White-colored spathes with dark pink-colored throats and dark pink-colored spadices.

3. Freely flowering habit.

Plants of the new Zantedeschia are most similar to plants of the parent plants. In side-by-side comparisons conducted in Steenbergen, The Netherlands, plants of the new Zantedeschia differed from plants of the female parent:

1. Plants of the new Zantedeschia were smaller than plants of the female parent.

2. Plants of the new Zantedeschia had white-colored spathes with dark pink-colored throats whereas plants of the female parent had solid white-colored spathes.

3. Plants of the new Zantedeschia had dark pink-colored spadices whereas plants of the female parent had yellow-colored spadices.

In side-by-side comparisons conducted in Steenbergen, The Netherlands, plants of the new Zantedeschia differed from plants of the male parent, the cultivar Marsh Mellow, in the following characteristics:

1. Plants of the new Zantedeschia were more freely flowering than plants of the cultivar Marsh Mellow.

2. Plants of the new Zantedeschia had white-colored spathes with dark pink-colored throats whereas plants of the cultivar Marsh Mellow had white-colored spathes with light pink-colored throats.

3. Plants of the new Zantedeschia had dark pink-colored spadices whereas plants of the cultivar Marsh Mellow had light pink to white-colored spadices.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the appearance of the new Zantedeschia, 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 Zantedeschia. The photograph is a close-up view of a typical inflorescence and leaves of ‘Red Desire’.

DETAILED BOTANICAL DESCRIPTION

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. The aforementioned photograph and following observations and measurements describe two-year old plants grown in Steenbergen, The Netherlands, in ground beds in a glass greenhouse without supplemental heat. During the production of the plants, day temperatures ranged from 2 to 22° C. and night temperatures ranged from −3 to 18° C. Light levels averaged 15,000 klux. The photographs and description were taken during the spring and summer.
