Anthurium cupulispathum Culture

Successful cultivation of the impressive Anthurium cupulispathum requires attention to its natural habitat conditions. Here are some essential cultural tips to ensure its thriving growth:

• Light: Anthurium cupulispathum prefers bright, indirect light. It thrives in filtered sunlight, similar to the dappled light of its native tropical forest understory.
• Temperature: This plant enjoys cool to intermediate temperatures, reflecting its high-altitude origins. Ideal daytime temperatures range between 15-25°C (59-77°F), with nighttime temperatures around 10-15°C (50-59°F).
• Humidity: High humidity is crucial for Anthurium cupulispathum, ideally between 70-80%. Use a humidifier, place the plant on a humidity tray, or grow it in a terrarium or enclosed environment to maintain adequate moisture levels.
• Watering: Water regularly, keeping the substrate evenly moist but not waterlogged. Allow the top layer of the substrate to dry slightly between waterings. Reduce watering during the winter months when growth slows.

Additional Notes:

• This is a large-sized plant, with leaves that can reach up to 2 meters (6.5 feet) in height and 1 meter (3.3 feet) in width, making it one of the most striking species in the genus.

• Anthurium cupulispathum produces massive inflorescences, consisting of a spadix (a spike of tiny flowers) and a spathe (a modified leaf). The spathe can measure up to 60 cm (24 inches) in length, making it one of the largest in the Anthurium genus.
