Abstract

A new and distinct cultivar of Kalanchoe plant named ‘Don Frederico’, characterized by its upright and freely branching plant habit; dark green-colored leaves; yellow-colored double flowers with multiple petals per flower; and excellent postproduction longevity.

Description

Botanical designation: Kalanchoe blossfeldiana.

Cultivar denomination: ‘Don Frederico’.

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 ‘Don Frederico’.

The new Kalanchoe is a product of a planned breeding program conducted by the Inventor in Naaldwijk, The Netherlands. The objective of the breeding program was to create new freely-flowering Kalanchoe cultivars with multiple flower petals, attractive flower coloration and excellent postproduction longevity.

The new Kalanchoe originated from a cross-pollination made in Naaldwijk, The Netherlands on Jun. 30, 2003, of a proprietary selection of Kalanchoe blossfeldiana identified as code number 2000033, not patented, as the female, or seed, parent with a proprietary selection of Kalanchoe blossfeldiana identified as code number 20000335-1, not patented, as the male, or pollen, parent. The new Kalanchoe was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination grown in a controlled environment in Naaldwijk, The Netherlands on Jul. 5, 2004.

Asexual reproduction of the new Kalanchoe by terminal cuttings at Naaldwijk, The Netherlands, has shown that the unique features of this new Kalanchoe are stable and reproduced true to type in successive generations.

BRIEF SUMMARY OF THE INVENTION

The cultivar Don Frederico has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment 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 ‘Don Frederico’. These characteristics in combination distinguish ‘Don Frederico’ as a new and distinct cultivar:

- 1. Upright and freely branching plant habit.
- 2. Dark green-colored leaves.
- 3. Yellow-colored double flowers with multiple petals per flower.
- 4. Excellent postproduction longevity.

Plants of the new Kalanchoe differ primarily from plants of the female parent selection primarily in flower color as plants of the female parent selection have purple-colored flowers.

Plants of the new Kalanchoe differ primarily from plants of the male parent selection in leaf color as plants of the male parent selection have darker green-colored leaves.

Plants of the new Kalanchoe can be compared to plants of the Kalanchoe cultivar Don Garcia, disclosed in a U.S. Plant Patent application Ser. No. 11/259,308. In side-by-side comparisons conducted in Naaldwijk, The Netherlands, plants of the new Kalanchoe differed from plants of the cultivar Don Garcia in the following characteristics:

- 1. Leaves of the plants of the new Kalanchoe had acute apices and bases whereas leaves of plants of the cultivar Don Garcia had rounded apices and bases.
- 2. Plants of the new Kalanchoe had yellow-colored flowers whereas plants of the cultivar Don Garcia had pink-colored 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 potted plant of ‘Don Frederico’.

The photograph at the bottom of the sheet comprises a close-up view of a typical flowering plant of ‘Don Frederico’.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used. Plants used in the photographs and for the following observations and measurements were grown in Naaldwijk, The Netherlands, under commercial practice in a glass-covered greenhouse for about 14 weeks after planting with day temperatures ranging from 20° C. to 30° C., night temperatures ranging from 18° C. to 25° C. and light levels ranging from 5 to 60 kilolux. Plants used in the description and photographs were not pinched.

Botanical classification: Kalanchoe blossfeldiana cultivar Don Frederico.
