Inflorescence (Spadix & Spathe)

• Greenish spathe and spadix
• Scent and pollination details may vary with environmental conditions

Growth Habit

• Terrestrial herb with a rhizomatous base, allowing for vigorous spread under optimal conditions

Light Requirements

• Prefers bright, indirect light to maintain optimal growth and vibrant foliage
