Amorphophallus konjac, commonly known as Voodoo Lily, produces one of the most unusual flowers in the plant world. In spring, a tall central spathe emerges in rich maroon-purple tones surrounding a prominent spadix. The bloom is short-lived but unforgettable. After flowering, the plant produces a single thick, mottled stem topped with an umbrella-like canopy of divided foliage, creating a sculptural presence in containers or shaded garden beds. The size of the plant and bloom is closely related to tuber size, with larger tubers producing more substantial growth. Care Amorphophallus konjac Care Plant tubers in spring once soil temperatures consistently exceed 55°F. Position tubers as deep as they are wide, ensuring the growth point faces upward. Grow in well-drained soil with moderate moisture. Water regularly during active growth but avoid saturated conditions. Allow foliage to remain intact until it naturally yellows and browns in fall, as this replenishes the tuber for the following season. In Zones 6 and colder, lift tubers after foliage dies back and store indoors in a cool, dry location until spring. Fertilize lightly during active growth with a slow release fertilizer. Container Growing: This plant is well suited to large patio containers. Use a well-draining potting mix and ensure the container has drainage holes. Container-grown plants require more consistent moisture monitoring. Plants hardy in the ground may require winter protection when grown in containers in colder zones.
