Abstract

A new and distinct cultivar of Kalanchoe plant named ‘Dark Jodie’, characterized by its compact, upright, uniform and moderately vigorous growth habit; medium-sized dark green-colored leaves; uniform and freely flowering habit; double red purple-colored flowers; and excellent postproduction longevity.

Description

Botanical designation: Kalanchoe blossfeldiana×Kalanchoe laciniata.

Cultivar denomination: ‘Dark Jodie’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Kalanchoe, botanically known as Kalanchoe blossfeldiana×Kalanchoe laciniata, and hereinafter referred to by the name ‘Dark Jodie’.

The new Kalanchoe is a naturally-occurring whole plant mutation of the Kalanchoe blossfeldiana×Kalanchoe laciniata cultivar Jodie, disclosed in U.S. Plant Pat. No. 17,980. The cultivar Dark Jodie was discovered and selected by the Inventor as a flowering plant from within a population of plants of the cultivar Jodie in a controlled environment in Hinnerup, Denmark in February, 2006.

Asexual reproduction of the new Kalanchoe by vegetative terminal cuttings in a controlled environment in Hinnerup, Denmark since April, 2006, has shown that the unique features of this new Kalanchoe are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar Dark Jodie has 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 ‘Dark Jodie’. These characteristics in combination distinguish ‘Dark Jodie’ as a new and distinct cultivar of Kalanchoe:

- 1. Compact, upright, uniform and moderately vigorous growth habit.
- 2. Medium-sized dark green-colored leaves.
- 3. Uniform and freely flowering habit.
- 4. Double red purple-colored flowers.
- 5. Excellent postproduction longevity.

Plants of the new Kalanchoe can be compared to plants of the parent, the cultivar Jodie. Plants of the new Kalanchoe differ from plants of the cultivar Jodie in the following characteristics:

- 1. Plants of the new Kalanchoe are more compact than plants of the cultivar Jodie.
- 2. Plants of the new Kalanchoe have slightly smaller flowers than plants of the cultivar Jodie.
- 3. Plants of the new Kalanchoe have fewer petals per flower than plants of the cultivar Jodie.
- 4. Plants of the new Kalanchoe and the cultivar Jodie differ in flower color as plants of the cultivar Jodie have soft pink-colored flowers.

Plants of the new Kalanchoe can be compared to plants of the Kalanchoe blossfeldiana×Kalanchoe laciniata cultivar Purple Jodie, disclosed in U.S. Plant patent application Ser. No. 12/006,220, filed concurrently. Plants of the new Kalanchoe differ from plants of the cultivar Purple Jodie in the following characteristics:

- 1. Plants of the new Kalanchoe are smaller than plants of the cultivar Purple Jodie.
- 2. Plants of the new Kalanchoe flower about four days earlier than plants of the cultivar Purple Jodie.
- 3. Plants of the new Kalanchoe and the cultivar Purple Jodie differ in flower color.

Plants of the new Kalanchoe can be compared to plants of the Kalanchoe blossfeldiana cultivar Dark Cora, disclosed in U.S. Plant Pat. No. 13,938. In side-by-side comparisons conducted in Hinnerup, Denmark, plants of the new Kalanchoe differed from plants of the cultivar Dark Cora in the following characteristics:

- 1. Plants of the new Kalanchoe had slightly smaller flowers than plants of the cultivar Dark Cora.
- 2. Plants of the new Kalanchoe had double flowers whereas plants of the cultivar Dark Cora had single flowers.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

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

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

The photograph at the bottom of the sheet comprises close-up views of a typical inflorescence, upper and side perspective views of typical flowers, and typical vegetative and generative leaves of ‘Dark Jodie’.

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 summer and under conditions which closely approximate commercial production. During the production of the plants, day temperatures were about 19° C., night temperatures were about 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 two weeks; plants then received photoinductive short day/long night conditions (minimum 14 hours darkness) until flowering. Plants were about twelve weeks old 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.
