BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Phalaenopsis plant, botanically known as Phalaenopsis hybrida, and hereinafter referred to by the name ‘PHA515727’.

The new Phalaenopsis plant is a product of a planned breeding program conducted by the Inventor in Bleiswijk, The Netherlands. The objective of the breeding program is to develop new freely flowering Phalaenopsis plants with flowers with unique and attractive patterns and coloration.

The new Phalaenopsis plant originated from a cross-pollination in January 2016 in Bleiswijk, The Netherlands of a proprietary selection of Phalaenopsis hybrida identified as code number 12-52030-02, not patented, as the female, or seed, parent with a proprietary selection of Phalaenopsis hybrida identified as code number 00001-4845, not patented, as the male, or pollen, parent. The new Phalaenopsis plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination grown in a controlled greenhouse environment in Bleiswijk, The Netherlands in September 2018.

Asexual reproduction of the new Phalaenopsis plant by in vitro meristem propagation in a controlled environment in Bleiswijk, The Netherlands since September 2018 has shown that the unique features of this new Phalaenopsis plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Phalaenopsis have been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature 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 ‘PHA515727’. These characteristics in combination distinguish ‘PHA515727’ as a new and distinct Phalaenopsis plant:

    • 1. Upright plant habit.
    • 2. Moderately vigorous growth habit.
    • 3. Strong flowering stems.
    • 4. Sturdy and healthy leaves.
    • 5. Freely flowering habit with typically two inflorescences developing per plant, each inflorescence with numerous flowers.
    • 6. White and reddish purple bi-colored flowers with yellow-colored labella.
    • 7. Good postproduction longevity.

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

    • 1. Flower petal margins of plants of the new Phalaenopsis are very slightly or not imbricate whereas flower petal margins of plants of the female parent selection are very undulate.
    • 2. Flower petals and sepals of plants of the new Phalaenopsis are white and reddish purple in color whereas flower petals and sepals of plants of the female parent selection are white and dark red in color.

Plants of the new Phalaenopsis can be compared to plants of the male parent selection. Plants of the new Phalaenopsis differ primarily from plants of the male parent selection in flower color as flower petals and sepals of plants of the new Phalaenopsis are white and reddish purple in color whereas flower petals and sepals of plants of the male parent selection are solid purplish red in color.

Plants of the new Phalaenopsis can be compared to plants of Phalaenopsis hybrida ‘Phalipue’, disclosed in U.S. Plant Pat. No. 33,312. In side-by-side comparisons, plants of the new Phalaenopsis differ primarily from plants of ‘Phalipue’ in the following characteristics:

    • 1. Leaves of plants of the new Phalaenopsis are positioned outwardly to downwardly arching whereas leaves of plants of ‘Phalipue’ are positioned mostly outwardly.
    • 2. Plants of the new Phalaenopsis have broader labella central lobes than plants of ‘Phalipue’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs illustrate the overall appearance of the new Phalaenopsis plant 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 Phalaenopsis plant.

The photograph on the first sheet (FIG. 1) is a side perspective view of a typical flowering plant of ‘PHA515727’ grown in a container.

The photograph on the second sheet (FIG. 2) is a close-up view of a typical flower of ‘PHA515727’.

 DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown during the summer in 12-cm containers in a glass-covered greenhouse in Bleiswijk, The Netherlands and under cultural practices typically used in commercial Phalaenopsis production. Plants were 18 months old when the photographs and description were taken. During the first 14 months of production of the plants, day and night temperatures averaged 28.5 C. During the final four months of production of the plants, day and night temperatures averaged 20 C.
