The Yellow Marilyn Monstera is a highly sought-after, rare, yellow-variegated, large form cultivar of Monstera deliciosa, known for its vibrant golden-yellow splashes against deep green, creating dramatic patterns on large, fenestrated leaves, requiring bright, indirect light, high humidity, chunky soil, and careful watering to maintain its unique coloration and prevent leaf burn, making it a stunning but moderately challenging tropical houseplant.
