  edible corms

Absolutely! Amorphophallus konjac is an edible corm! Various Amorphophallus
are consumed in Asia, not only the corms but also the very young petiole
and leaf, before they open. You can make a high carb flour from A. konjac.

That leads me to wonder, though, if you harvest the petiole and young leaf,
will the corm send up a second leaf or is the growing point now gone and
the corm will die in the ground? The web site I was on referred to people
stir frying the Amorphophallus leaves, but didn't mention any details of
the "farming" operation.

Dear Les and Ken,

Edible rhizomes would be Xanthosoma (the 'malangas'), ginger 'root', etc.!
When the young leaves are harvested from Amorphophallus, another leaf is
produced. We must presume that there are MANY plants being grown in a
field, so the same young leaf is not repeatedly harvested from the same
tuber, much like the harvesting in my native land of young leaves from a
stand of Colocasia for Sunday 'calaloo'. The people who use Amorphophallus
leaves probably choose the smaller, more tender leaves from 'attending'
smaller tubers growing near to and around the main plant, which does not
affect the main tuber production.

Perhaps I missed something. I thought earlier that Amorphophallus was classified as having tubers rather than corms. (I know this has been discussed at length in the past but I don't recall the upshot.)

Haven't people been calling the Amorphophallus "things" tubers rather than corms?

I'm not sure it was ever really resolved. The reason I'm calling them a corm
is because my friend Matt Opel, soon to receive his PhD in botany from the
University of Connecticut, told me that it's a corm! His explanation to me
was that a corm gets used up and replaced during the growing season, which
is true of Amorphophallus.

If that's the wrong information, don't blame me! I'm a programmer, not a
botanist or a horticulturist...
