Kalanchoe plant named ‘Pago’

Abstract

A new and distinct cultivar of Kalanchoe plant named ‘Pago’, characterized by its numerous large yellow orange and orange bi-colored flowers; upright, uniform and compact plant habit; freely branching growth habit; dark green glossy leaves; early flowering; and excellent postproduction longevity.

Description

Botanical designation: Kalanchoe blossfeldiana.

Cultivar denomination: ‘Pago’.

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 ‘Pago’.

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 was to create new freely-branching and freely-flowering Kalanchoe cultivars with attractive foliage and flower coloration.

The new Kalanchoe is a naturally-occurring whole plant mutation of the Kalanchoe blossfeldiana cultivar Petero, disclosed in U.S. Plant Pat. No. 12,155. The cultivar Pago was discovered and selected by the Inventor as a single flowering plant within a population of plants of the parent cultivar in a controlled environment in De Lier, The Netherlands, in December, 1999.

Asexual reproduction of the new Kalanchoe by terminal vegetative cuttings taken at De Lier, The Netherlands, since 2000 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 Pago 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 ‘Pago’. These characteristics in combination distinguish ‘Pago’ as a new and distinct cultivar:

• • 1. Large and numerous yellow orange and orange bi-colored flowers.
  • 2. Upright, uniform and compact plant habit.
  • 3. Freely branching growth habit.
  • 4. Dark green-colored glossy leaves.
  • 5. Early flowering.
  • 6. Excellent postproduction longevity.

Plants of the new Kalanchoe are most similar to plants of the parent, the cultivar Petero. In side-by-side comparisons conducted by the Inventor in De Lier, The Netherlands, plants of the new Kalanchoe differed from plants of the cultivar Petero in the following characteristics:

• • 1. Plants of the new Kalanchoe were more compact than plants of the cultivar Petero.
  • 2. Plants of the new Kalanchoe were more freely branching than plants of the cultivar Petero.
  • 3. Plants of the new Kalanchoe flowered earlier than plants of the cultivar Petero.
  • 4. Plants of the new Kalanchoe had tighter (not as open) umbels than plants of the cultivar Petero.
  • 5. Flower color of plants of the new Kalanchoe was yellow orange and orange bi-colored whereas flower color of plants of the cultivar Petero was orange.

Plants of the new Kalanchoe can also be compared to plants of the cultivar Klabat, disclosed in U.S. Plant Pat. No. 10,454. In side-by-side comparisons conducted in De Lier, The Netherlands, plants of the new Kalanchoe differed from plants of the cultivar Klabat in the following characteristics:

• • 1. Plants of the new Kalanchoe were more compact than plants of the cultivar Klabat.
  • 2. Plants of the new Kalanchoe flowered earlier than plants of the cultivar Klabat.
  • 3. Plants of the new Kalanchoe and the cultivar Klabat differed in flower coloration.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates 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 photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Kalanchoe. The photograph comprises a side perspective view of a typical potted plant of ‘Pago’.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used. Plants used for the aforementioned photograph and for the description were grown during the autumn in De Lier, The Netherlands, in a glass-covered greenhouse. During the production of the plants, day temperatures ranged from 20 to 25° C.; night temperatures ranged from 19 to 21° C.; and light levels ranged from 10,000 to 50,000 lux. Unrooted cuttings were directly stuck in 12.5-cm containers and received long day/short night conditions (more than 14 hours of light) for about three weeks; plants then received photoinductive short day/long night conditions (minimum 14 hours darkness) until flowering. Plants were about 13 weeks old from an unrooted cutting when the photograph and the description were taken.

• Propagation:
  • • Type cutting.—Terminal vegetative cuttings.
    • Time to initiate roots.—Summer: About 12 days at 21° C. Winter: About 15 days at 21° C.
