Amorphophallus paeoniifolius is a native bulb plant of Thailand. It is named in Thai after its distinctive skin as "toad konjac".
Also know as Elephant Foot Yam, Elephant Yam or Whitespot Giant Arum
This plant grows well in sandy soil mix that provides good drainage. Too much water can cause root rot. It prefers shade to partial sunlight. The top of the bulb is to be faced up just like onions.
In the cold season, they will shed leaves, and new bulbs are dormant just like they have stopped growing. When dormant, do not give too much water. Let the soil dry out. Keep it dry for a couple of weeks and then water it again. Do not fertilize. Repeat this process until the bulb wakes up in the spring. At that time you can start watering regularly.
Hardy Zones 11-12 or indoors/patio plant in warmer months
