Philodendron plant named ‘BVCL01’

Abstract

‘BVCL01’ is a distinctive Philodendron plant which is characterized by uniquely variegated laminas with variegated foliage comprised of a light pink base coloration and irregular blotches of varying size and color, from magenta to dark pink, green to greyed-green, and brown; as well as vivid magenta petioles and petiole wings with dark pink irregular longitudinal stripes, and the stability of all characteristics from generation to generation.

Description

[0001] Latin name of the genus and species: The Latin name of the genus and species of the novel variety disclosed herein is Philodendron erubescens.

[0002] Variety denomination: The inventive variety of Philodendron disclosed herein has been given the variety denomination ‘BVCL01’.BACKGROUND OF THE INVENTION

[0003] Parentage: ‘BVCL01’ is a spontaneous whole-plant mutation which was first discovered in July of 2024 at a commercial greenhouse facility in Phatthana Nikhom, Thailand, growing amongst a cultivated population of Philodendron erubescens ‘Pink Princess’ plants (not patented). The mutation was first noted for its unique foliage variegation, relative to the bicolored variegation of ‘Pink Princess’. Meristematic tissue was harvested from said mutation and in vitro micropropagation was first performed in October of 2024. The resulting plurality of tissue cultured plantlets produced were subsequently grown in a greenhouse for two generations to confirm the stability and relative uniformity of the unique foliage colorations. In December of 2024, the resulting plants were determined to have a stable, unique variegation pattern and were selected for further propagation. This new plant was given the name ‘BVCL01’.

[0004] Asexual Reproduction: Asexual reproduction of the new cultivar ‘BVCL01’, by way of meristematic tissue culture micropropagation, was first initiated in 2024 in Phatthana Nikhom, Thailand. Through two subsequent generations, the unique features of this cultivar have proven to be stable and true to type.SUMMARY OF THE INVENTION

[0005] The cultivar ‘BVCL01’ 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 ‘BVCL01’. These characteristics in combination distinguish ‘BVCL01’ as a new and distinct Philodendron cultivar:

[0006] 1. Philodendron ‘BVCL01’ exhibits uniquely variegated laminas with a light pink base coloration and irregular blotches of varying size and color, from magenta to dark pink, green to greyed-green, and brown; and

[0007] 2. Philodendron ‘BVCL01’ exhibits vivid magenta petioles and petiole wings with dark pink irregular longitudinal striation, and the stability of all characteristics from generation to generation.BRIEF DESCRIPTION OF THE FIGURES

[0008] 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 ‘BVCL01’ grown in a commercial greenhouse in Phatthana Nikhom, Thailand. These plants are approximately 14 months old, in a 10 cm container.

[0009] FIG. 2 illustrates, as nearly true as it is reasonably possible to make the same in color photographs of this type, the mature foliage's adaxial surface of ‘BVCL01’.

[0010] FIG. 3 illustrates, as nearly true as it is reasonably possible to make the same in color photographs of this type, the mature foliage's abaxial surface of ‘BVCL01’.BOTANICAL DESCRIPTION OF THE PLANT

[0011] The following observations and measurements, made in May of 2025, describe averages from a 14-month-old ‘BVCL01’ plant grown in a 10 cm nursery container at commercial greenhouse in Phatthana Nikhom, Thailand. Plants were produced using conventional greenhouse production protocols for Philodendron species which consisted of overhead irrigation once every two days and routine application of a granular 13-13-13. Plants were grown under shade (ranging from 5,000 to 25,000 lux) with ambient temperatures ranging from 26 to 38 degrees Celsius and humidity levels ranging from 70 to 90 percent.

[0012] Those skilled in the art will appreciate that certain characteristics will vary with older or, conversely, with younger plants. ‘BVCL01’ 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, Sixth Edition.

[0013] A botanical description of ‘BVCL01’ and a comparison with the parent plant and most similar commercial cultivar are provided below.

[0014] Plant description:

[0015] Growth habit.—Broad spreading to upright herbaceous perennial with foliage growth from basal shoots.

[0016] Plant profile shape.—Globular to flattened globular.

[0017] Height.—13.2 cm at approximately 14 months of age.

[0018] Width.—25 cm at approximately 14 months of age.

[0019] Number of basal shoots per plant.—1.

[0020] Propagation.—Type — Asexual propagation is accomplished by way of meristematic tissue culture micropropagation. Time to initiate roots — Approximately 4 to 6 weeks to initiate roots at an average ambient temperature of 21 degrees Celsius. Crop time — Approximately 16 to 20 weeks to produce a well-rooted, marketable 10 cm container from a rooted cutting.

[0021] Disease and pest resistance or susceptibility.—Neither susceptibility nor resistance to pests and diseases common to other Philodendron have been observed.

[0022] Environmental tolerances.—Adapt to temperatures as low as 5 degrees Celsius and at least as high as 40 degrees Celsius.

[0023] Roots:

[0024] Density.—Not very dense.

[0025] Texture.—Fleshy, non-fibrous.
