Re: Amorphophallus bulbifer -size to bloom

my bulbifer plants usually flower when about 3 feet tall. I had maybe 7
flowers this spring, aound May.
my paeonifolius plants are about the same, flowering when 3 to 4 feet tall.
I had about 20 flowers this spring, also about May. The biggest flowers
will wait to put up a leaf until next spring. My biggest leaf now is about
8 feet, from a big flower last year.
Don't need to worry about the smell though, because my wife makes me cut
them all down when the flies start buzzin'
