Last spring we had one of these growing on a side table in the dining room. One day my son and I came home for lunch and I smelled a disgusting odour as soon as we sat down to eat. Naturally, I blamed the little guy and started reprimanding him for making stinks at the table. He insisted that he didn't have to go, and that the stink was not coming from him! Then we noticed the plant. The voodoo lily had bloomed and was the source of the offending stench! Of course I appologized to my son and we took the stinky thing to the school for show-and-tell. The kids loved it! Everyone made faces and "Eew! Gross!" comments then came back giggling for more. The teachers looked it up on the internet and integrated it into their lessons. I planted it later, and it grew into the palm tree shaped plant but it died while we were on vacation. Yesterday I bought a new one, and one for my sister. They must be quite popular here because I have been visiting the store weekly looking for them and still took the last two voodoos on the shelf!

Potted can be sunken into a water garden or bulbs can be planted directly into the soil. They are very frost sensitive, and should be lifted dried and stored during the winter. Even if grown in a tropical climate they will enter a dormant phase.

Grown as a food crop in parts of the world; leaf stalk is mottled pink with green, very beautiful unusual foliage. Mature tubers can weigh up to 50 lbs.

Konjac is the easiest of all the amorphaphallus species to grow for novices, and usually stays at a manageable height. As with many of the arum species, the flowers have a very disagreeable odor to attract pollinating flies.
