[0003] The Applicant asserts that no publications or advertisements relating to sales, offers for sale, or public distribution occurred more than one year prior to the effective filing date of this application. Any information about the claimed plant would have been obtained from a direct or indirect disclosure from the Inventor. The Applicant claims a prior art exemption under 35U.S.C. 102 (b)(1) for disclosures and / or sales that fall within a one-year grace period prior to the filing date. This application claims priority to CPVO application No. 2025 / 0241 filed on Feb. 4, 2025.BACKGROUND OF THE NEW PLANT

[0004] The present invention comprises a new and distinct variety of Monstera plant, botanically known as Monstera adansonii, and hereinafter referred to by the variety name ‘ELSTMN0424’. The new Monstera cultivar is a product of a planned breeding program located in Rijsenhout, The Netherlands. The new cultivar is a naturally occurring branch mutation originating from an unnamed and unpatented population of Monstera adansonii plants cultivated in a greenhouse in Rijsenhout, The Netherlands. Several mutations were selected by the inventor from said population of Monstera adansonii plants for over one year. The mutations were grown in 14 cm pots and observed for uniformity, stability, and distinctness as well as for their commercial potential. From amongst these mutations, ‘ELSTMN0424’ was selected by the inventor in September 2023 for further propagation and commercialization based on its unique plant shape, fast growth rate, compactness and small leaf size.

[0005] The new Monstera cultivar ‘ELSTMN0424’ was first reproduced asexually using meristematic tissue culture in September 2023 in Rijsenhout, The Netherlands. Asexual propagation by meristematic tissue culture of the new variety has shown that the unique features of the new variety are stable and reproduced true-to-type to date through 8 successive generations.SUMMARY OF THE INVENTION

[0006] The new Monstera cultivar ‘ELSTMN0424’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, light intensity, water status, fertilizer rate and type, without, however, any variance in genotype.

[0007] The following are the most outstanding and distinguishing characteristics of this new Monstera cultivar. The combination of these characteristics distinguishes ‘ELSTMN0424’ as a new and distinct variety of Monstera.

[0008] 1. Monstera ‘ELSTMN0424’ exhibits leaves with numerous small-sized fenestrations creating a denser and more perforated leaf appearance.

[0009] 2. Monstera ‘ELSTMN0424’ exhibits a medium green leaf coloration with no variegation.

[0010] 3. Monstera ‘ELSTMN0424’ exhibits a compact and trailing growth habit with pendulous branches.DESCRIPTION OF THE PHOTOGRAPHS

[0011] This new Monstera cultivar is illustrated by the accompanying-colored photographs which show the overall appearance and distinct characteristics of the plant. The colors shown are as true as can be reasonably obtained by conventional photographic procedures.

[0012] The photographs are 1-year-old plants grown in 17-centimeter circular containers in a conventional glass greenhouse in Rijsenhout, The Netherlands. Colors in the photographs may differ slightly from the color values cited in the botanical description which accurately describes the colors of the new variety.

[0014] FIG. 2. shows a close-up of a typical mature leaf of ‘ELSTMN0424’.DESCRIPTION OF THE NEW VARIETY

[0015] In the following description, color references are made to The Royal Horticultural Society Colour Chart, Sixth Edition, except where general color terms of ordinary dictionary significance are used.

[0016] The following observations and measurements describe plants grown in a conventional glass greenhouse located in Rijsenhout, The Netherlands. Growing condition consisted of an average day and night temperature of 20° C. to 22° C., 60 to 85 percent relative humidity, 150-200 μmol / m2 / sec (PAR) of light, and 600 to 700 ppm of CO2. Detailed descriptions were taken in December 2024. from 1-year-old plants grown in 17-centimeter circular containers. Measurements and numerical values represent averages of typical plant types.DETAILED BOTANICAL DESCRIPTION
