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 ‘Cliffhanger’.

The new Phalaenopsis plant is a product of a planned breeding program conducted by the Inventor in Den Hoorn and Heemskerk, The Netherlands. The objective of the breeding program is to develop new fast-growing and freely flowering Phalaenopsis plants with good leaf shape and large flowers with unique and attractive patterns and coloration.

The new Phalaenopsis plant originated from a cross-pollination in January, 2011 in Den Hoorn, The Netherlands of a proprietary selection of Phalaenopsis hybrida identified as code number 1006336, not patented, as the female, or seed, parent with a proprietary selection of Phalaenopsis hybrida identified as code number 1006337, 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 Heemskerk, The Netherlands in June, 2017.

Asexual reproduction of the new Phalaenopsis plant by in vitro meristem propagation in a controlled environment in Assendelft, The Netherlands since June, 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 ‘Cliffhanger’. These characteristics in combination distinguish ‘Cliffhanger’ as a new and distinct Phalaenopsis plant:

• • 1. Upright plant habit.
  • 2. Moderately vigorous to vigorous growth habit.
  • 3. Strong flowering stems.
  • 4. Strong leaves.
  • 5. Freely flowering habit with typically two inflorescences per plant, each inflorescence with numerous flowers.
  • 6. Large white-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 flower shape as petals of plants of the new Phalaenopsis are free to touching whereas petals of plants of the female parent selection are free and not touching. In addition, sepals of plants of the new Phalaenopsis are overlapping whereas sepals of plants of the female parent selection are free and not overlapping.

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 the following characteristics:

• • 1. Plants of the new Phalaenopsis are taller than plants of the male parent selection.
  • 2. Plants of the new Phalaenopsis have larger flowers than plants of the male parent selection.
  • 3. Plants of the new Phalaenopsis have white-colored flowers with yellow-colored labella whereas plants of the male parent selection have white-colored flowers with faint pink-colored stripes and red-colored labella.

Plants of the new Phalaenopsis can be compared to plants of Phalaenopsis hybrida ‘Navigator’, not patented. In side-by-side comparisons, plants of the new Phalaenopsis differ primarily from plants of ‘Navigator’ in flower shape as petals of plants of the new Phalaenopsis are free to touching whereas petals of plants of ‘Navigator’ are free and not touching. In addition, the curvature of the labellum is stronger in plants of the new Phalaenopsis than plants of ‘Navigator’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown during the late autumn in 10.5-cm containers in a glass-covered greenhouse in Heemskerk, 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 twelve months of production of the plants, day and night temperatures averaged 27° C. During the final six months of production of the plants, day temperatures ranged from 20° C. to 22° C. and night temperatures ranged from 18° C. to 20° C. During the 18 months of production, light levels ranged from a minimum of 5,000 lux to a maximum of 10,000 lux.
