plant named ‘GUOQIAN’

‘GUOQIAN’ is a new and distinctive Philodendron tatei plant which is characterized by the combination of a relatively large stature, large glossy foliage borne on prominent red petioles, juvenile foliage that is colored with a mixture of yellow-green and greyed-brown on the upper surface and greyed-orange with yellow-green suffusion on the lower surface, mature foliage that is colored dark green on the upper surface and yellow-green with greyed-orange suffusion on the lower surface, and the stability of all characteristics from generation to generation.

Description

Latin name of the genus and species: The Latin name of the genus and species of the novel variety disclosed herein is Philodendron tatei.

Variety denomination: The inventive variety of Philodendron disclosed herein has been given the variety denomination ‘GUOQIAN’.

BACKGROUND OF THE INVENTION

Parentage: ‘GUOQIAN’ is a spontaneous whole-plant mutation which was discovered growing amongst a cultivated population of greenhouse-grown Philodendron tatei ‘Rojo Congo’ plants (U.S. Plant Pat. No. 14,116) which was first observed by the inventor in 2018 at a commercial nursery in the Panyu district of Guangzhou, China. The mutation was first noted for its uniquely-colored leaves relative to those of the parent plant and was subsequently isolated for further evaluation in order to confirm the distinctness and stability of the characteristics first observed. From 2018 through 2022, the claimed plant was evaluated against other comparators, at multiple secure and confidential sites. Upon confirmation of distinctness and stability, the new Philodendron plant was selected for commercialization and given the name ‘GUOQIAN’.

Asexual Reproduction: Asexual reproduction of the new cultivar ‘GUOQIAN’, by way of vegetative division, was first initiated in 2019, at a nursery in Foshan, China. Through twelve subsequent generations, the unique features of this cultivar have proven to be stable and true to type.

SUMMARY OF THE INVENTION

The cultivar ‘GUOQIAN’ 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 ‘GUOQIAN’. These characteristics in combination distinguish ‘GUOQIAN’ as a new and distinct Philodendron cultivar:

    • 1. Philodendron ‘GUOQIAN’ exhibits a relatively large plant size with large, glossy foliage; and
    • 2. Philodendron ‘GUOQIAN’ exhibits juvenile foliage that is colored with a mixture of yellow-green and greyed-brown adaxially, and greyed-orange with yellow-green suffusion, abaxially; and
    • 3. Philodendron ‘GUOQIAN’ exhibits mature foliage that is colored dark green adaxially, and yellow-green with greyed-orange suffusion abaxially; and
    • 4. Philodendron ‘GUOQIAN’ exhibits dark greyed-orange to greyed-red petioles, which generally appear red.

BRIEF DESCRIPTION OF THE FIGURES

FIG. 1 illustrates, as nearly true as it is reasonably possible to make the same in color photographs of this type, an exemplary plant of ‘GUOQIAN’ grown in a commercial plant nursery in Guangzhou, China. This plant is approximately 12 months old in a 13 cm container.

FIG. 2 illustrates, as nearly true as it is reasonably possible to make the same in color photographs of this type, the adaxial surface of the juvenile foliage of ‘GUOQIAN’.

FIG. 3 illustrates, as nearly true as it is reasonably possible to make the same in color photographs of this type, the adaxial surface of the mature foliage of ‘GUOQIAN’.

 BOTANICAL DESCRIPTION OF THE PLANT

The following observations and measurements, made in November of 2023, describe averages from a 12-month-old ‘GUOQIAN’ plant grown in 13 cm nursery containers at a commercial plant nursery in Guangzhou, China. Plants were produced using conventional production protocols for Philodendron sp. which consisted of growing plants under shade cloth, regular overhead irrigation, supplemental fertilizer as needed, and chemical pest measures to control both disease and insect pests.

Those skilled in the art will appreciate that certain characteristics will vary with older or, conversely, with younger plants. ‘GUOQIAN’ has not been observed under all possible environmental conditions. Where dimensions, sizes, colors and other characteristics are given, it is to be understood that such characteristics are approximations or averages set forth as accurately as practicable. The phenotype of the variety may differ from the descriptions set forth herein with variations in environmental, climatic and cultural conditions. Color notations are based on The Royal Horticultural Society Colour Chart, The Royal Horticultural Society, London, 2015 (sixth edition).

A botanical description of ‘GUOQIAN’ and a comparison with the parent plant and most similar commercial cultivar are provided below.
