Name: Amorphophallus konjac

Description & Notes: A striking, tuber-forming aroid with a single, highly divided leaf that resembles a small treetop. During the growing season, the plant grows vigorously from its underground tuber. Once the leaf dies back, it enters a pronounced dormant phase. Older, sufficiently large tubers can produce the characteristic large inflorescence.

Light: Bright to partial shade with plenty of indirect light. It tolerates some mild morning or evening sun, but avoid intense midday sun.

Temperature: Warm to moderate during growth, ideally around 20–28 °C. During dormancy, the dry tuber can be stored at considerably cooler temperatures, but should be protected from frost.

Water & Humidity: Once the new growth is clearly developing, water regularly and keep the substrate evenly slightly moist, but avoid waterlogging. When the leaf turns yellow and dies back in autumn or at the end of the growing season, gradually reduce watering until it stops. Keep the tuber dry throughout the dormant phase.

Substrate: Nutrient-rich, humusy, loose, and well-draining. A mix of high-quality potting soil with mineral components such as perlite, pumice, or coarse sand works well. Fertilize regularly but moderately during active growth.
