History / Discovery / Cultivator

The Amorphophallus konjac, commonly known as the Voodoo Lily, Devil’s Tongue, or Konjac, boasts a history deeply intertwined with Asian cultures, particularly in China and Japan. Its origins trace back to the subtropical and tropical regions of eastern Asia, where it has been cultivated for centuries for both culinary and medicinal purposes.

While the exact date of its discovery remains somewhat obscured by time, historical records indicate that Amorphophallus konjac has been utilized in China for over 2,000 years. Ancient Chinese texts mention its use as a detoxifying agent and for treating various ailments, demonstrating an early understanding of its unique properties.

The cultivation of Konjac is believed to have begun in China and subsequently spread to Japan, Korea, and other Southeast Asian countries. In Japan, Konjac gained prominence as a staple food, particularly during periods of famine, thanks to its low-calorie content and ability to provide a feeling of fullness. It was also favored by Buddhist monks, who adhered to a vegetarian diet. The Japanese developed various methods of processing and preparing Konjac, transforming it into products like Shirataki noodles and Konnyaku, a gelatinous cake.

The plant’s scientific name, Amorphophallus konjac, was formally established within botanical taxonomy. The term “Amorphophallus” originates from the Greek words “amorphos” (shapeless) and “phallos” (penis), alluding to the shape of the plant’s spadix, the central flowering spike. “Konjac” is derived from the Japanese name for the plant.

While specific individuals responsible for the initial cultivation or popularization of Amorphophallus konjac are not definitively recorded, its widespread adoption across Asian cultures signifies a collective effort over generations. Farmers and agricultural communities played a crucial role in developing cultivation techniques and adapting the plant to different environments. In modern times, researchers and agricultural scientists have continued to study Konjac, exploring its potential for various applications, including food production, medicine, and even the creation of biodegradable plastics. It has also found its way into Western horticulture as an exotic ornamental plant.

The Voodoo Lily’s journey from a wild plant to a cultivated crop and a subject of scientific interest reflects its versatility and enduring appeal. Its historical roots are deeply embedded in the agricultural practices and culinary traditions of Asia, and its future potential continues to be explored in various fields around the globe. Its fascinating life cycle, bizarre bloom, and intriguing uses ensure its continued recognition in both scientific and horticultural circles.

Plant Care Summary

Botanical Insights

Adaptations

Amorphophallus konjac exhibits several remarkable adaptations. Its most striking adaptation is its massive inflorescence, which emits a strong, foul odor resembling rotting meat. This scent attracts carrion beetles and flies, which serve as pollinators. The plant also possesses a large underground corm, which acts as a storage organ for nutrients and water, enabling it to survive unfavorable conditions, such as drought or cold winters. The mottled pattern on the pseudostem provides camouflage, helping it blend in with its surroundings in the forest understory. Finally, the rapid growth of the foliage during the growing season allows the plant to quickly capitalize on available sunlight and resources.

Propagation Methods

Several methods can be used to propagate Amorphophallus konjac:

• Corm Offsets: The easiest method is to separate and plant small cormlets (offsets) that develop around the main corm.
• Seed: While possible, propagation by seed is slow and requires patience. The seeds need to be fresh and sown in a well-draining medium.
• Corm Cutting: Larger corms can be cut into sections, each containing an eye (bud), and allowed to callous over before planting. This method requires careful attention to prevent rot.

Toxicology

All parts of the Amorphophallus konjac plant contain calcium oxalate crystals. If ingested, these crystals can cause immediate and intense pain and burning sensations in the mouth, throat, and esophagus. Swelling, drooling, and difficulty swallowing or breathing may also occur. While rarely life-threatening, ingestion can be extremely uncomfortable. For pets like cats and dogs, the symptoms are similar. Keep this plant away from children and pets. If ingestion occurs, rinse the mouth thoroughly with water and seek medical or veterinary attention immediately.

Common Problems

Pests:

• Spider mites
• Aphids
• Mealybugs

Diseases:

• Corm rot (fungal or bacterial)
• Leaf spot

Other:

• Leaf yellowing: Overwatering or poor drainage
• Failure to bloom: Insufficient light or an immature corm
• Corm rot during dormancy: Storing corms in excessively moist conditions

Rarity & Value

Rarity:

While not exceedingly rare in cultivation, large, mature specimens of Amorphophallus konjac with well-established corms are less common. Its unusual appearance and the infrequent blooming cycle, which can take several years to occur, contribute to its desirability among collectors. Certain cultivars with unique foliage patterns may also command higher prices.

Value:

The value of an Amorphophallus konjac specimen typically depends on its size, the maturity of the corm, and its overall health. Larger corms, which are more likely to produce a flower, fetch higher prices. Additionally, the novelty and spectacle of the bloom itself contribute to the plant’s perceived value. Current collector trends favoring unusual or “monster” plants can also influence demand and pricing.
