Epipremnum aureum plant named ‘Global Green’

Latin name of the genus and species of the plant claimed: Epipremnum aureum.

Varietal denomination: ‘Global Green’.

None.

None.

The present invention relates to a new and distinct cultivar of Epipremnum , botanically known as Epipremnum aureum , and hereinafter referred to by the name ‘Global Green’.

The new Epipremnum plant cultivar was discovered by Hiroaki Asaoka in May 2016 in a plant nursery in Aichi, Japan. The instant plant was the result of a mutation that was naturally occurring. Asexual reproduction of the ‘Global Green’ by vegetative cuttings was first performed in September, 2016 in Aichi, Japan and has shown that the unique features of this cultivar are stable and reproduced true to type in successive generations of asexual reproduction.

The cultivar ‘Global Green’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, 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 ‘Global Green’. These characteristics in combination distinguish ‘Global Green’ as a new and distinct Epipremnum aureum cultivar:

1. Centered green variegated leaves, with a more monochromatic appearance and more defined areas within which each of the two colors resides. 2. Patch of moderate yellow green color, of varying shape and size on either side of the midrib, on moderate olive-green background on a single leaf. 3. Mid-sized ovate/egg-shaped leaf with a pointy top. 4. Stems moderately strong with light yellow green and moderate yellow green colored appearance.

Plants of ‘Global Green’ can be compared to plants of the species selection, Epipremnum aureum . However, ‘Global Green’ differs from the plants of the mutation species selection in the following characteristics:

1. Plants of ‘Global Green’ produced variegated leaves that have two colors, where the primary color is moderate yellow green and the secondary color is moderate olive green. 2. Plants of ‘Global Green’ produced stems that were longer and slightly thicker. 3. Plants of ‘Global Green’ display ovate/egg shaped leaves with a pointy top. 4. Plants of ‘Global Green’ are wider and more dense.

The accompanying colored photographs illustrate the overall appearance of the new Epipremnum showing the colors as true as it is reasonably possible to obtain in color reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description of the new variety which accurately describes the colors of the new Epipremnum plant.

The aforementioned photographs and the following observations, measurements, and values describes plants of the new Epipremnum grown in Aichi, Japan in conditions of 60% shading and 24 hr ventilation all year around in 9 cm containers and under cultural practices of commercial Epipremnum production. During the production of the plants, temperatures ranged from about 20 (winter)-40 (highest in summer) degrees Celsius and light levels were normal sunlight.

Plants were growing about 3.5 months when the photographs and the description were taken. However, it should be noted that the cultivar ‘Global Green’ can grow up to 30 cm tall, maybe taller given time, if grown in larger pots. Even at this height, the characteristics of the ‘Global Green’ as described remain true.

The following is a detailed description of the new plant characteristics with color in terminology in accordance with The Royal Horticultural Society Colour Chart, Edition V (2007), except where ordinary dictionary significance of color is indicated.
