Unveiling the Enigma of Amorphophallus konjac (Voodoo Lily): The Fascinating World of Corpse Flowers

Is this the coolest house plant to own? In my opinion….yes. Well at least I can say with confidence that this is MY PERSONAL coolest HOUSE PLANT in my entire collection!

Voodoo lilies, scientifically known as Amorphophallus konjac, have long intrigued botanists, horticulturists, and plant enthusiasts with their captivating foliage, unique characteristics, and exotic origins. Native to the warm subtropical to tropical regions of eastern Asia, including Vietnam, Japan, China, and Indonesia, these perennial plants have earned a place of curiosity and wonder in gardens worldwide. In this comprehensive guide, we delve deep into the world of Voodoo lilies, exploring their history, cultivation, and various species, while shedding light on their remarkable features and versatile uses.

Corpse Plant (Voodoo Plant)

The Fascinating Origins of Voodoo Lilies, or amorphophallus konjac

Amorphophallus konjac, commonly referred to as Voodoo lily, belongs to the Araceae family, which includes well-known plants like philodendrons and peace lilies. The Voodoo lily is renowned for its striking appearance, characterized by a single, massive leaf that emerges from a subterranean tuber. Despite being widely grown for its aesthetics and unique characteristics, this enigmatic plant has been known by several scientific names throughout history, including A. rivieri, A. rivieri var. konjac, A. mairei, and Hydrosme rivieri. Its many common names, such as Devil's tongue, dragon plant, elephant yam, konnyku, leopard arum, snake palm, and umbrella arum, only add to its mystique.

The Allure of Edible Tubers

One of the most intriguing aspects of Voodoo lilies is their starchy tubers, which are not just for show but also serve as a source of sustenance. In various parts of the world, these tubers are cultivated for food. When processed, they yield a tasteless flour or a firm jelly, often used as a vegan substitute for gelatin. In Japan, konjac flour is used to create shirataki noodles, while the starch finds its way into a popular Asian fruit jelly snack. The Voodoo lily's versatility extends beyond its ornamental value, making it a valuable addition to culinary traditions.

Anatomy and Growth Habits

The growth habits and anatomy of Voodoo lilies are as intriguing as their name. The globose tuber, which can reach an astonishing 50 pounds and a foot in diameter, serves as the anchor for the plant's growth. As the new leaf begins to emerge, the tuber gradually diminishes, replaced by a new, larger tuber during the growing season. The fleshy leaf stalk, or petiole, adds to the plant's allure with its captivating mottled pinkish-gray and olive green hues. The leaf itself is a botanical marvel, featuring a horizontal blade attached to the vertical petiole, which is divided into three sections, creating a mesmerizing umbrella-like effect.

The leaf blade, deeply dissected and comprised of numerous small leaflets, exhibits remarkable intricacy. With multiple branches on the petiole, mature specimens often take on the appearance of small trees. The size of the leaf is directly proportional to the size of the tuber, resulting in leaves that can stretch up to an impressive 4 feet in diameter. In optimal conditions, Voodoo lily plants can attain heights of 4 to 6 feet. However, even in tropical climates, these plants demand a dry, dormant period annually. Consequently, the leaf, representing a single growing season, naturally senesces in late summer or fall.

Exquisite Blooms with an Unusual Aroma

While Voodoo lilies are celebrated for their foliage, they also produce fascinating blooms that are unlike any other. Larger tubers, typically the size of a grapefruit or larger, may produce a single inflorescence in late winter or spring, preceding the emergence of foliage. A robust stalk supports a substantial, shiny brown-purple to maroon ruffled spathe, which can extend up to 3 feet, enshrouding the longer pale green to purple or mottled spadix, a flower spike featuring a fleshy axis.

These monoecious plants showcase tiny individual female flowers (pistils) at the bottom of the spadix, a zone of stamens (the male flowers), and a sterile region at the top. The plant emits an odor reminiscent of a deceased animal during flowering, a scent designed to attract carrion flies, their natural pollinators. For those who find the odor objectionable, the flower can be removed or enclosed in a plastic bag to contain the smell. Pollinated flowers may eventually yield a spherical berry, although this occurrence is infrequent in homegrown plants. After flowering, it can take a month or more before the new leaf emerges.

Grow Voodoo Lily: Tips and Techniques

Growing Voodoo lilies can be a rewarding experience. Overall, it's an easy to grow experience, but it's essential to understand their specific requirements. As a tender plant, the leaf is highly sensitive to frost, necessitating indoor cultivation as a houseplant or seasonal outdoor growth. In regions with shorter growing seasons, such as the Midwest, it is often advisable to start tubers indoors and transition them outdoors once nighttime temperatures remain above 55ºF. Tubers can be planted directly in the ground, partially sunk in a container below the rim, or maintained in containers on a patio or deck.

Voodoo lilies thrive in rich, organic soil or a soil-less growing medium. This is my favorite tropical soil mix, and I highly recommend it to all plant parents. Tubers should be planted when the pinkish growing tips become visible. Because the roots emerge not from the base of the tuber but from the top and grow horizontally to support the leaf, it's essential to plant the tubers deep, approximately as far below the soil surface as the tuber's width. Ensure that the container's diameter is at least twice the width of the tuber to accommodate the spreading roots. These warm-weather plants only thrive in suitable conditions, tolerating anything from full shade to full sun, but they tend to flourish in partial sunlight.

Voodoo lily grows best with consistent moisture, and they can even tolerate standing in water; potted Voodoo lilies can be submerged in a shallow water garden. These plants are heavy feeders and can be generously fertilized throughout the growing season. As the leaf starts to senesce in late summer or fall, allow the growing medium to dry, refraining from further fertilization. Outdoor containers should be tipped over to facilitate complete drying. Avoid cutting off the leaf until it has turned completely brown.

Winter Dormancy and Propagation

During the winter dormancy period, tubers can remain in their pots with dry growing medium or be stored in peat moss. It's typically recommended to wait until spring to separate any small new tubers from the parent plant. In either case, the tubers should be kept on the drier side to prevent rotting, in relatively warm conditions (42-50°F). Voodoo lilies readily produce offsets, making propagation relatively simple. You can achieve this by separating the snake-like, stoloniferous tubers with rounded ends from the parent plant. While they can also be grown from seed, this method is less commonly available.

Exploring the Diversity of Voodoo Lilies

While Amorphophallus konjac is the most well-known and widely cultivated Voodoo lily species, it's worth noting that the genus Amorphophallus encompasses a diverse range of species, each with its own unique characteristics. Let's explore some of the notable Voodoo lily species:

  • Amorphophallus titanum (Titan Arum): Often referred to as the "corpse flower," this species is renowned for its enormous size and pungent odor, which can be likened to rotting flesh. It produces one of the largest inflorescences in the plant kingdom and is a rare and sought-after sight in botanical gardens around the world.

  • Amorphophallus bulbifer: Commonly known as the "voodoo bulb," this species produces small offsets, or bulbils, around the base of the leaf stalk. These bulbils can be separated and planted to propagate new plants, making it a popular choice for enthusiasts.

  • Amorphophallus paeoniifolius: This species, native to Southeast Asia, is valued for its edible corms, which are used in various culinary preparations. It's also known for its striking foliage and is sometimes grown as an ornamental plant.
