Abstract

A new and distinct cultivar of Kalanchoe plant named ‘Desert Surprise’, characterized by its tall, upright, uniform and moderately vigorous growth habit; green and dark purple bi-colored leaves with undulate and crenate margins; freely flowering habit; small red purple-colored flowers; and excellent postproduction longevity.

Description

Botanical designation: Kalanchoe humilis.

Cultivar denomination: ‘DESERT SURPRISE’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Kalanchoe plant, botanically known as Kalanchoe humilis, and hereinafter referred to by the name ‘Desert Surprise’.

The new Kalanchoe plant is a product of a planned breeding program conducted by the Inventor in Hinnerup, Denmark. The objective of the breeding program is to create new Kalanchoe plants with unique and interesting foliage and flower forms and coloration.

The new Kalanchoe plant originated from a self-pollination made by the Inventor in Hinnerup, Denmark in January, 2008, of a proprietary selection of Kalanchoe humilis identified as code number 0077, not patented. The new Kalanchoe was discovered and selected by the Inventor as a flowering plant from within the progeny of the stated self-pollination in a controlled greenhouse environment in Hinnerup, Denmark on May 12, 2008.

Asexual reproduction of the new Kalanchoe plant by vegetative terminal cuttings in a controlled greenhouse environment in Hinnerup, Denmark since Jun. 9, 2008, has shown that the unique features of this new Kalanchoe plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Kalanchoe have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices such as temperature, daylength 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 ‘Desert Surprise’. These characteristics in combination distinguish ‘Desert Surprise’ as a new and distinct cultivar of Kalanchoe:

- 1. Tall, upright, uniform and moderately vigorous growth habit.
- 2. Green and dark purple bi-colored leaves with undulate and crenate margins.
- 3. Freely flowering habit.
- 4. Small red purple-colored flowers.
- 5. Excellent postproduction longevity.

Plants of the new Kalanchoe can be compared to plants of the parent selection. Plants of the new Kalanchoe differ from plants of the parent selection primarily in plant uniformity.

Plants of the new Kalanchoe can be compared to plants of the proprietary selection of Kalanchoe humilis identified as code number KJ 2008 5043, not patented. In side-by-side comparisons conducted in Hinnerup, Denmark, plants of the new Kalanchoe differed from plants of the proprietary selection KJ 2008 5043 in the following characteristics:

- 1. Plants of the new Kalanchoe and the proprietary selection KJ 2008 5043 differed in leaf color as plants of the proprietary selection had less pronounced dark purple markings.
- 2. Plants of the new Kalanchoe and the proprietary selection KJ 2008 5043 differed in flower color as plants of the proprietary selection had white and dark purple-colored flowers.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Kalanchoe plant, 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 Kalanchoe plant.

The photograph on the first sheet comprises a side perspective view of a typical flowering plant of ‘Desert Surprise’ grown in a container.

The photograph on the second sheet comprises a top perspective view of a typical flowering plant of ‘Desert Surprise’ grown in a container.

The photograph on the third sheet comprises close-up views of typical vegetative (bottom left) and generative (bottom right) leaves, a side perspective view of a typical inflorescence (top) and individual flowers (center) of ‘Desert Surprise’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown in Hinnerup, Denmark in a glass-covered greenhouse during the winter and spring and under conditions which closely approximate commercial Kalanchoe humilis production. During the production of the plants, day temperatures averaged 19° C., night temperatures averaged 21° C. and light levels ranged from 10 kilolux to 50 kilolux. Unrooted cuttings were directly stuck in 10-cm containers and received long day/short night conditions (more than 14 hours of light) for about five weeks; plants then received photoinductive short day/long night conditions (minimum 14 hours darkness) until flowering. Plants were 25 weeks from planting when the photographs and the description were taken. In the detailed description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used.
