I've been doing some Aroid propagation experiments this year with almost
100 percent success.

I've had success with several species of Amorphophallus and Psuedodracontium.
And in a couple of weeks, may be able to add Caladium to the 'successful'

Unlike some others, I do not use the upper part of the leaf.  I use only
the petiole.  I cut into 3-4 inch sections and stick them in a mixture of
pinebark and perlite, then put them underneath a trash bag for 6 to 8
weeks.  After that the part of the petiole cutting above the ground has
whithered, but a bulbil has formed underground.

One particular failure was with Synandrospadix...only tried one single
cutting.  I doubt this would have worked as the petiole tissue was
quite 'airy'.
