(Konjac) Call it what you like -- Corpse Flower, Devil's Tongue, Elephant Yam, Voodoo Lily or just plain Konjac -- but Amorphophallus konjac is a super sized surprise. It's native to subtropical and tropical Asian woodlands where it tolerates both cold and heat.

This member of the family Araceae can rise up shoulder high, but is related to the much shorter aroids Jack-in-the-Pulpit (Arisaema triphyllum) and Farge's Cobra Lily (A. fargesii).

The large dark flower is displayed on a tall stalk for up to a month in the early spring. Once flowering ends, a highly ornamental leaf resembling a finely cut umbrella emerges rapidly and grows up to four feet tall and wide. The leaf remains until the end of the growing season.

Konjac corms can remain in ground in Zones 6 - 10. In areas with colder winters, dig them up for storage until the next growing season. We offer two- and three-year-old corms -- growing in deep perennial pots -- which should bloom in one to two years.

Asian cultures -- especially the Japanese -- eat Konjac root as a gummy product called yam cake, which is often made into shirataki noodles. Yam cake has little flavor and is more firm than gelatin. It is also used to make washi, a tough paper that is traditionally used to make clothing and other durable items.
