Abstract

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

Description

Botanical designation: Kalanchoe blossfeldiana.

Cultivar denomination: ‘Megan’.

BACKGROUND OF THE INVENTION

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

The new Kalanchoe 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 double-flowered Kalanchoe cultivars with attractive foliage and flower coloration.

The new Kalanchoe, originated from a cross-pollination made by the Inventor in Hinnerup, Denmark in April, 2005, of the Kalanchoe blossfeldiana cultivar KJ 2003 1487, not patented, as the female, or seed parent with the Kalanchoe blossfeldiana cultivar Juliana 2000, not patented, as the male, or pollen, parent. The cultivar Megan was discovered and selected by the Inventor as a flowering plant from within the progeny of the stated cross-pollination in a controlled environment in Hinnerup, Denmark in November, 2005.

Asexual reproduction of the new Kalanchoe by vegetative terminal cuttings in a controlled environment in Hinnerup, Denmark since March, 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 Megan 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 ‘Megan’. These characteristics in combination distinguish ‘Megan’ as a new and distinct cultivar of Kalanchoe:

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

Plants of the new Kalanchoe can be compared to plants of the female parent, the cultivar KJ 2003 1487. Plants of the new Kalanchoe differ from plants of the cultivar KJ 2003 1487 primarily in petal quantity as plants of the new Kalanchoe have flowers with more petals than plants of the cultivar KJ 2003 1487.

Plants of the new Kalanchoe can also be compared to plants of the male parent, the cultivar Juliana 2000. Plants of the new Kalanchoe differ from plants of the cultivar Juliana 2000 in the following characteristics:

- 1. Plants of the new Kalanchoe and the cultivar Juliana 2000 differ in leaf shape as leaves of plants of the cultivar Juliana 2000 have more cordate-shaped bases.
- 2. Plants of the new Kalanchoe have double flowers whereas plants of the cultivar Juliana 2000 have single flowers.

Plants of the new Kalanchoe can be compared to plants of the Kalanchoe blossfeldiana cultivar Cate, not patented. In side-by-side comparisons conducted in Hinnerup, Denmark, plants of the new Kalanchoe differed from plants of the cultivar Cate in the following characteristics:

- 1. Plants of the new Kalanchoe were more compact than plants of the cultivar Cate.
- 2. Plants of the new Kalanchoe and the cultivar Cate differed in leaf shape as leaves of plants of the cultivar Cate had more cordate-shaped bases.
- 3. Flowers of plants of the new Kalanchoe had fewer petals than flowers of plants of the cultivar Cate.

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 on the first sheet comprises a side perspective view of a typical flowering plant of ‘Megan’ grown in a container.

The photograph on the second sheet comprises close-up views of typical vegetative (top left) and generative (top right) leaves, upper (center left) and side (center right) perspective views of typical flowers and a side perspective view of a typical flowering stem (bottom) of ‘Megan’.

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 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 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 eleven 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.
