Abstract

A new and distinct cultivar of Kalanchoe plant named ‘Grace’, characterized by its large, upright, uniform and moderately vigorous growth habit; large dark green-colored leaves; uniform and freely flowering habit; large double white-colored flowers; and excellent postproduction longevity.

Description

Botanical designation: Kalanchoe blossfeldiana.
Cultivar denomination: ‘Grace’.
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 ‘Grace’.
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 large 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 September, 2004, of the Kalanchoe blossfeldiana cultivar KJ 2003 0818, disclosed in U.S. Plant patent application Ser. No. 11/080,401, as the female, or seed parent with the Kalanchoe blossfeldiana cultivar KJ 2001 0934, disclosed in U.S. Plant Pat. No. 16,376, as the male, or pollen, parent. The cultivar Grace 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 May, 2005.
Asexual reproduction of the new Kalanchoe by vegetative terminal cuttings in a controlled environment in Hinnerup, Denmark since July, 2005, 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 Grace 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 ‘Grace’. These characteristics in combination distinguish ‘Grace’ as a new and distinct cultivar of Kalanchoe:
    • 1. Large, upright, uniform and moderately vigorous growth habit.
    • 2. Large dark green-colored leaves.
    • 3. Uniform and freely flowering habit.
    • 4. Large double white-colored flowers.
    • 5. Excellent postproduction longevity.
Plants of the new Kalanchoe can be compared to plants of the female parent, the cultivar KJ 2003 0818. Plants of the new Kalanchoe differ from plants of the cultivar KJ 2003 0818 in the following characteristics:
    • 1. Plants of the new Kalanchoe have longer leaves than plants of the cultivar KJ 2003 0818.
    • 2. Plants of the new Kalanchoe have larger flowers with more petals than plants of the cultivar KJ 2003 0818.
    • 3. Plants of the new Kalanchoe and the cultivar KJ 2003 0818 differ in flower color as plants of the cultivar KJ 2003 0818 have pink-colored flowers.
Plants of the new Kalanchoe can also be compared to plants of the male parent, the cultivar KJ 2001 0934. Plants of the new Kalanchoe differ from plants of the cultivar KJ 2001 0934 in the following characteristics:
    • 1. Plants of the new Kalanchoe have double flowers whereas plants of the cultivar KJ 2001 0934 have single flowers.
    • 2. Plants of the new Kalanchoe and the cultivar KJ 2001 0934 differ in flower color as plants of the cultivar KJ 2001 0934 have light pink-colored flowers.
Plants of the new Kalanchoe can be compared to plants of the Kalanchoe blossfeldiana cultivar Yazmin, disclosed in U.S. Plant patent application Ser. No. 11/358,831. In side-by-side comparisons conducted inn Hinnerup, Denmark, plants of the new Kalanchoe differed from plants of the cultivar Yazmin in the following characteristics:
    • 1. Plants of the new Kalanchoe were broader than plants of the cultivar Yazmin.
    • 2. Plants of the new Kalanchoe had longer leaves than plants of the cultivar Yazmin.
    • 3. Plants of the new Kalanchoe were more freely flowering than plants of the cultivar Yazmin.
    • 4. Plants of the new Kalanchoe had larger flowers than plants of the cultivar Yazmin.
    • 5. Flowers of plants of the new Kalanchoe had more petals than flowers of plants of the cultivar Yazmin.
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 ‘Grace’ grown in a container.
The photograph at the bottom of the sheet comprises a top perspective view of a typical flowering plant of ‘Grace’.
 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 autumn and 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 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 15 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.
