Description

Botanical designation: Kalanchoe blossfeldiana.

Cultivar denomination: ‘White Sands’.

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 ‘White Sands’.

The new Kalanchoe is a product of a planned breeding program conducted by the Inventor in Aalsmeer and Middelburg, The Netherlands. The objective of the breeding program was to create new compact and freely-branching Kalanchoe cultivars with attractive foliage and flower coloration.

The new Kalanchoe originated from a cross made by the Inventor in October, 2000 in Aalsmeer, The Netherlands of a proprietary selection of Kalanchoe blossfeldiana identified as code number 96053, not patented, as the female, or seed, parent with a proprietary selection of Kalanchoe blossfeldiana identified as code number 96145-11, not patented, as the male, or pollen, parent. The cultivar White Sands was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross in a controlled environment in Middelburg, The Netherlands in August, 2001.

Asexual reproduction of the new Kalanchoe by terminal vegetative cuttings taken at Aalsmeer, The Netherlands, since August, 2001 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 White Sands 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 ‘White Sands’. These characteristics in combination distinguish ‘White Sands’ as a new and distinct cultivar:

    • 1. White-colored flowers.
    • 2. Upright and uniform plant habit.
    • 3. Freely branching growth habit.
    • 4. Early and freely flowering habit.
    • 5. Excellent postproduction longevity.

Plants of the new Kalanchoe can be compared to plants of the parent selections. In side-by-side comparisons conducted by the Inventor in De Kwakel, The Netherlands, plants of the new Kalanchoe had larger flowers than the female parent selection and had stronger roots than the male parent selection.

Plants of the new Kalanchoe can also be compared to plants of the Kalanchoe cultivar Mie, not patented. In side-by-side comparisons conducted by the Inventor in De Kwakel, The Netherlands, plants of the new Kalanchoe differed from plants of the cultivar Mie in the following characteristics:

    • 1. Plants of the new Kalanchoe had stronger roots than plants of the cultivar Mie.
    • 2. Plants of the new Kalanchoe were more freely branching than plants of the cultivar Mie.
    • 3. Plants of the new Kalanchoe had fuller and less open inflorescences than plants of the cultivar Mie.
    • 4. Plants of the new Kalanchoe had larger flowers than plants of the cultivar Mie.

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 ‘White Sands’.

 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 Kwakel, The Netherlands, in a glass-covered greenhouse. During the production of the plants, day and night temperatures averaged 20° C. and light levels were about 500 Watt/m2. Unrooted cuttings were directly stuck in 10.5-cm containers and received long day/short night conditions (about 15 hours of light) for about four weeks; plants then received photoinductive short day/long night conditions (minimum 15 hours darkness) until flowering. Plants were about 15 weeks old from an unrooted cutting when the photograph and the description were taken.

  • Botanical classification: Kalanchoe blossfeldiana cultivar White Sands.
  • Parentage:
      • Female or seed parent.—Proprietary selection of Kalanchoe blossfeldiana identified as code number 96053, not patented.
      • Male, or pollen, parent.—Proprietary selection of Kalanchoe blossfeldiana identified as code number 96145-11, not patented.
  • Propagation:
      • Type cutting.—Terminal vegetative cuttings.
      • Time to initiate roots.—Summer: About 10 days at 20° C. Winter: About 14 days at 20° C.
      • Time to produce a rooted young plant.—Summer: About 21 days at 20° C. Winter: About 25 days at 20° C.
      • Root description.—Fine, fibrous; brown in color.
      • Rooting habit.—Freely branching; moderately dense.
  • Plant description:
      • Form/growth habit.—Upright, uniform and compact plant habit. Very freely flowering with numerous compound cymes. Inverted triangle with rounded crown. Vigorous growth habit; rapid growth rate.
      • Plant height at flowering.—About 14 cm.
      • Plant diameter at flowering.—About 18 cm.
      • Branching habit.—Freely branching; typically six lateral branches develop per plant. Pinching (removal of terminal apex) is not required but will enhance lateral branch development.
      • Lateral branch description.—Length: About 12 cm. Diameter: About 4 cm. Internode length: About 1 cm. Aspect: Erect. Strength: Strong. Texture: Smooth, glabrous. Color: Close to 147A.
