The Split Leaf Philodendron, widely recognized for its dramatic, perforated foliage, is a popular houseplant. While commonly referred to by this name, it is botanically known as Monstera deliciosa, and it is not a true philodendron. Despite the common misconception that this plant rarely blooms indoors, Monstera deliciosa can indeed produce a flower, particularly when it reaches maturity and is provided with optimal growing conditions. This signifies a thriving and well-established plant.
Understanding the Split Leaf Philodendron Flower
The “flower” of the Monstera deliciosa is technically an inflorescence, a complex structure composed of several parts. It features a creamy-white or pale yellow, boat-shaped bract known as a spathe, which encloses a central, fleshy spike called a spadix. This spadix is densely covered with numerous tiny, individual flowers. The entire structure typically measures about 8 to 12 inches (20-38.4 cm) in length.
The appearance of the Monstera deliciosa inflorescence is similar to that of a peace lily, as both plants belong to the Araceae family. While flowering is common in its native tropical habitats, it is less frequently observed in indoor environments.
Conditions for Flowering
Encouraging a Monstera deliciosa to flower depends on the plant’s maturity, typically after 5 to 10 years for indoor specimens. A robust root system is also a prerequisite.
Bright, indirect light is important; insufficient light hinders flowering and leaf perforations. Avoid direct sunlight, which can scorch leaves.
Consistent high humidity (60-80%) benefits flowering, mimicking its native rainforest. Achieve this with misting, pebble trays, or a humidifier. Proper watering is also important; allow soil to dry slightly between thorough waterings. Overwatering causes root issues, while underwatering stresses the plant.
Balanced fertilization during the active growing season provides necessary nutrients. A nutrient-rich, well-draining soil mix supports overall health. Maintain a stable, warm temperature (18-30°C / 65-86°F). Providing a support structure, like a moss pole, allows the plant to climb and mature, encouraging blooming by mimicking its natural habit.
From Flower to Fruit
Following successful flowering, the Monstera deliciosa spadix develops into a unique, elongated fruit resembling a green ear of corn covered in hexagonal scales. This fruit ripens slowly, often requiring 10 to 18 months. As it matures, green scales lift and fall away, revealing creamy, yellowish flesh and a sweet, tropical aroma.
The ripe fruit is edible, with a taste described as a blend of tropical flavors like pineapple, banana, mango, passion fruit, and strawberry. However, only fully ripe fruit is safe for consumption. All other plant parts, including leaves, stems, roots, and especially unripe fruit, contain insoluble calcium oxalate crystals.
Ingesting unripe fruit or other plant parts causes immediate and intense irritation, characterized by a burning sensation, pain, and swelling of the lips, mouth, tongue, and throat. To ensure safety, consume only portions where hexagonal scales have easily detached, indicating full ripeness and dissipation of irritating compounds.
