Native to parts of eastern and south-east Asia, it develops from a large underground corm and goes through distinct periods of active growth and dormancy.\u003cspan class=\"PDq2pG_selectionAnchor\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eDuring its foliage stage, Amorphophallus konjac produces \u003cstrong\u003ea single impressive leaf from the corm\u003c\/strong\u003e, but this one leaf is so highly divided that it can easily be mistaken for an entire small tree. A thick, upright, mottled stem-like petiole supports a broad canopy of branching green leaflets, giving the plant an exotic, almost prehistoric appearance. The petiole itself is particularly striking, typically patterned with irregular shades of green, cream and pinkish-brown.\u003c\/p\u003e\n\u003cp\u003eMature corms can produce the plant's remarkable flower before the foliage emerges. A tall central spadix is surrounded by a large, funnel-shaped spathe, usually displaying rich \u003cstrong\u003eburgundy, purple and reddish-brown tones\u003c\/strong\u003e. Its dramatic appearance is accompanied by the feature responsible for its famous common name: the flower can produce a powerful odour resembling decaying organic matter. This scent attracts flies and other insects that act as natural pollinators. Fortunately, the smell is temporary and is strongest while the flower is at its peak.\u003c\/p\u003e\n\u003cp\u003eAfter flowering, or when growing from a younger corm, the foliage emerges and remains throughout the active growing season. Eventually the leaf naturally yellows and dies back, at which point the plant enters dormancy. This is a normal and essential part of its lifecycle rather than a sign that the plant has died.\u003c\/p\u003e\n\u003cp\u003eAmorphophallus konjac is a fantastic choice for collectors looking for something genuinely unusual. Its combination of spectacular foliage, rapid seasonal growth and one of the plant world's most distinctive flowers makes it a fascinating specimen to grow year after year.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePlease note:\u003c\/strong\u003e Amorphophallus konjac naturally enters dormancy. Depending on the time of year and its growth cycle, plants may arrive at different stages of development. The distinctive flower is produced by sufficiently mature corms and cannot be guaranteed each season.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch1\u003eAmorphophallus konjac Care Guide\u003c\/h1\u003e\n\u003ch3\u003eLight\u003c\/h3\u003e\n\u003cp\u003eProvide \u003cstrong\u003ebright, indirect light to partial shade\u003c\/strong\u003e while the plant is actively growing. Amorphophallus konjac appreciates plenty of light but its foliage can be damaged by prolonged, intense direct sunlight, particularly through glass.\u003c\/p\u003e\n\u003cp\u003eA position receiving gentle morning or late-afternoon sun can work well, but protect the foliage from strong midday summer sun.\u003c\/p\u003e\n\u003cp\u003eOnce the plant has entered full dormancy and the foliage has disappeared, light is no longer important until growth resumes.\u003c\/p\u003e\n\u003ch3\u003eWatering\u003c\/h3\u003e\n\u003cp\u003eWater regularly during active growth, allowing the upper few centimetres of compost to dry slightly between waterings.\u003c\/p\u003e\n\u003cp\u003eOnce the large leaf is fully established, the plant can use a considerable amount of water, particularly during warm weather.
