Abstract

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

Description

Botanical designation: Kalanchoe blossfeldiana.
Cultivar denomination: ‘Don Juan’.
CROSS-REFERENCE TO RELATED APPLICATIONS
The present application is co-pending with the following related application: Title: Kalanchoe Plant Named ‘Don Domingo’. Applicant: Leonardus Johannes Maria van der Knaap.
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 Juan’.
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 May 26, 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 20000102-1, 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 Apr. 19, 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 Juan 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 Juan’. These characteristics in combination distinguish ‘Don Juan’ as a new and distinct cultivar:
    • 1. Upright and freely branching plant habit.
    • 2. Dark green-colored leaves.
    • 3. Red-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. In addition, plants of the new Kalanchoe and the female parent selection differed in leaf margin.
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. Plants of the new Kalanchoe and the male parent selection differ in flower color as plants of the male parent selection have yellow-colored flowers.
Plants of the new Kalanchoe differ from plants of the Kalanchoe cultivar Don Domingo, disclosed in a U.S. Plant patent application Ser. No. 11/259,310. In side-by-side comparisons, plants of the new Kalanchoe differ primarily from plants of the cultivar Don Domingo in flower color as plants of the cultivar Don Domingo have salmon orange-colored flowers. In addition, plants of the new Kalanchoe have more petals per flower than plants of the cultivar Don Domingo.
Plants of the new Kalanchoe can also be compared to plants of the Kalanchoe cultivar Don Frederico, disclosed in a U.S. Plant patent application Ser. No. 11/259,309. In side-by-side comparisons conducted in Naaldwijk, The Netherlands, plants of the new Kalanchoe differed from plants of the cultivar Don Frederico in the following characteristics:
    • 1. Leaves of plants of the new Kalanchoe had rounded apices and obtuse bases whereas leaves of plants of the cultivar Don Frederico had acute apices and bases.
    • 2. Plants of the new Kalanchoe had red-colored flowers whereas plants of the cultivar Don Frederico had yellow-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 Juan’.
The photograph at the bottom of the sheet comprises a close-up view of a typical flowering plant of ‘Don Juan’.
 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.
