Amorphophallus barbatus

Amorphophallus barbatus is a rare and intriguing species of the Araceae family, discovered in 2015 by Alan Galloway and Annop Ongsakul. It has striking dark velvet leaves and is far and away the most beautiful amorphophallus leaf in our opinion.

It is an extremely rare species which is known from a single location only in central Laos. So far, fewer than a dozen plants have been observed in the wild during three documented excursions over the past decade. These tubers are leaf clones from in-vitro tubers of the original plant that the description was made of. These original tubers were distributed to us in 2021 for a donation made to help cover costs for research studies on the genus Amorphophallus in habitat, for publishing undescribed species, and for maintaining a part of late Dr. Alan Galloway’s live Amorphophallus and Typhonium collection

These tubers will require at least two or maybe three additional growing seasons to reach flowering size.

Native to
Amorphophallus barbatus is native to central Laos, where it is restricted to a single known location. This tropical region provides the high humidity, warm temperatures, and seasonal growth cycles the plant requires.

Water
During the active growth phase, the soil should remain consistently moist but never waterlogged, as excessive moisture can lead to tuber rot. During dormancy, watering should be significantly reduced, ensuring the soil remains just slightly damp to protect the tuber.

Light
This plant thrives in bright, indirect light. Direct sunlight can damage the foliage, so filtered light or partial shade is ideal. Proper lighting is essential for robust growth and to encourage flowering.

Humidity
High humidity levels above 70% are necessary for Amorphophallus barbatus to thrive. In the UK, a terrarium is a suitable option for creating this humid environment, especially for smaller tubers. Alternatively, a humidifier or a pebble tray can help maintain the required humidity.

Temperature
Warm, stable temperatures are critical for this species. Daytime temperatures around 22C and nighttime temperatures not dropping below 19C are ideal. Avoid exposing the plant to cold drafts or fluctuating temperatures, especially during its active growing season.
