A list is a good idea. If it contained photos of
the petiole and the leaf of all of the species, it would be a GREAT idea.

how tall do they get?
Randy,
I think this is something most Amorphophallus
growers are interested in. The list you propose is a very good idea!
I would like to take the chance
to add the question how tall they get at a definite tuber size (lets say at
good light and growing conditions):
Would any one know, if there is a close correlation between tuber size
and PETIOLE HIGHT in Amorphophallus titanum?
If someone has figures or even an idea, I would be
very intersted. (It could tell me when to built a higher greenhouse for my
A.t. or do something different; see below)
I ask this in the same context as I asked for the effect of growth
retardants on the petiole hight of A.t. or other big aroids with a single leaf
some time ago. I did not get a response when I posted my question, but I think
it should work, since growth retardants generally inhibit cell elongation to a
certain extent. (Normally they are used in horticulture to shorten internode
length in ornamentals like Poinsettias and others)
Looking forward to any comment!
