Description

Botanical designation: Kalanchoe blossfeldiana.

Cultivar denomination: ‘FICALANJAMAICA’.

BACKGROUND OF THE INVENTION

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

The new Kalanchoe is a product of a planned breeding program conducted by the Inventor in De Lier, The Netherlands. The objective of the breeding program is to create new freely-branching and freely-flowering Kalanchoe plants with double flowers and attractive foliage and flower coloration.

The new Kalanchoe plant originated from a cross-pollination made by the Inventor in Odense, Denmark in September, 2006 of a proprietary selection of Kalanchoe blossfeldiana identified as code number 1110 (05), not patented, as the female, or seed, parent with a proprietary selection of Kalanchoe blossfeldiana identified as code number 9185-02 (05), not patented, as the male, or pollen, parent. The new Kalanchoe plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled environment in De Lier, The Netherlands.

Asexual reproduction of the new Kalanchoe plant by vegetative terminal cuttings in a controlled environment in De Lier, The Netherlands since 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 and cultural practices. The phenotype may vary somewhat with variations in environmental conditions 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 ‘Ficalanjamaica’. These characteristics in combination distinguish ‘Ficalanjamaica’ as a new and distinct Kalanchoe plant:

• • 1. Compact, upright and uniformly mounded plant habit.
  • 2. Moderately vigorous growth habit.
  • 3. Freely branching plant habit.
  • 4. Glossy dark green-colored leaves.
  • 5. Uniform and freely flowering habit.
  • 6. Double bright yellow-colored flowers.
  • 7. Excellent postproduction longevity.

Plants of the new Kalanchoe can be compared to plants of the female parent selection. Plants of the new Kalanchoe differ from plants of the female parent selection in the following characteristics:

• • 1. Plants of the new Kalanchoe are more compact than plants of the female parent selection.
  • 2. Plants of the new Kalanchoe are more freely branching than plants of the female parent selection.
  • 3. Plants of the new Kalanchoe have smaller leaves than plants of the female parent selection.
  • 4. Plants of the new Kalanchoe and the female parent selection differ in flower color as plants of the female parent selection have orange-colored flowers.

Plants of the new Kalanchoe can be compared to plants of the male parent selection. Plants of the new Kalanchoe differ from plants of the male parent selection in the following characteristics:

• • 1. Plants of the new Kalanchoe have double flowers whereas plants of the male parent selection have single flowers.
  • 2. Flowers of plants of the new Kalanchoe are brighter yellow in color than flowers of plants of the male parent selection.

Plants of the new Kalanchoe can be compared to plants of the Kalanchoe blossfeldiana ‘Golden Girl’, not patented. In side-by-side comparisons conducted in De Lier, The Netherlands, plants of the new Kalanchoe differed from plants of ‘Golden Girl’ in the following characteristics:

• • 1. Plants of the new Kalanchoe were more compact than plants of ‘Golden Girl’.
  • 2. Plants of the new Kalanchoe were more freely branching than plants of ‘Golden Girl’.
  • 3. Plants of the new Kalanchoe had smaller leaves than plants of ‘Golden Girl’.
  • 4. Plants of the new Kalanchoe and ‘Golden Girl’ differed in flower color as plants of ‘Golden Girl’ had yellow orange-colored flowers.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates 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 photograph 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 comprises a side perspective view of a typical flowering plant of ‘Ficalanjamaica’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations, measurements and values describe plants grown during the summer and autumn in 10-cm containers in a glass-covered greenhouse in De Lier, The Netherlands and under conditions which closely approximate commercial Kalanchoe production. During the production of the plants, day temperatures ranged from 20° C. to 22° C., night temperatures ranged from 19° C. to 21° C. and light levels ranged from 10,000 lux to 50,000 lux. Plants received long day/short night conditions (more than 14 hours of light) for about three weeks then plants received photoinductive short day/long night conditions (minimum 14 hours darkness) until flowering. Plants were 17 weeks old when the photograph and the description were taken. In the detailed description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
