Amorphophallus operculatus
Amorphophallus operculatus is a unique tuberous perennial known for its striking, highly divided leaves and unusual growth cycle. During the growing season, it produces a large, singular leaf that can reach impressive heights. The leaf is dark green, almost appearing black, with a subtle pink margin along the edges, adding an extra layer of visual interest. This species undergoes a period of dormancy, during which the leaf dies back completely, leaving only the underground tuber until the next season.
Native to: Amorphophallus operculatus is native to the tropical forests of Thailand. It typically grows in the shaded understory, thriving in the moist, humid conditions found in these regions.
Water: During its active growth phase, this plant prefers consistently moist soil but requires excellent drainage to prevent tuber rot. Water it regularly when the soil’s surface begins to dry, reducing watering as the plant enters its dormancy. During dormancy, allow the soil to dry out completely and resume watering only when new growth appears.
Light: Amorphophallus operculatus does best in bright, indirect light, similar to the filtered sunlight it would receive in its native habitat. Avoid direct sunlight, which can cause the dark leaves to scorch.
Humidity: This plant thrives in moderate to high humidity, with levels between 50% and 70%. Increased humidity during the growing season can help maintain the health and vibrancy of its dark, pink-edged foliage. Regular misting or the use of a humidity tray is recommended.
Temperature: Amorphophallus operculatus prefers warm temperatures ranging from 20°C to 30°C during its growing period. Protect it from temperatures below 15°C during dormancy to prevent damage to the tuber​
