  Leaflet variability in Amorphophallus konjac?
From: ken at spatulacity.com on 2003.10.06 at 15:52:43(10688)
Have list members noticed much variability in the shape of Amorphophallus
konjac leaflets? I got a handful of offsets from a friend, which looked
like konjac (I saw the mother corm) and tossed them in with mine. Now I have
a bunch of plants with significantly rounded leaflets compared with the
konjacs they're growing with. They're so different that I can easily spot
them amongst the 50+ offsets that I grew this year.

My friend's corm flowered this spring. I've asked him to describe it and I
gave him a link to the konjac page on aroid.org. He's not an aroider by
nature and acquired the corm randomly from someone in the cactus club, I

Thanks in advance,
Ken Mosher

Different clones vary widely. My 'Leo Song Variant' is fnely cut while
Tony Avent's 'Nightstick' has more 'solid' leaves. Yet within clones you
see some great variability especially when they are leaves from small
corms. I have a clone that I collect all the corms from and when you
plant them you would think they were seedling derived in year one or two
because they show great variability. In time, they all seem to merge to
the same phenotype. Just my experience.

Dear Ken,

I am not an Amorphophallus grower, but think that you will find a LOT of variability in not only A. konjac leaflets, but this species as a whole.
Many years ago when this list was done by snail mail, Fanny Phillips described her collection of A. konjac, she had dwarfs that bloomed small blooms the size of a white rat (photo was supplied), and giants whose bloom towered above her 6' tall husband, my friend Craig. There also was every color of petiole you could imagine, so you are in for many surprises as you obtain other clones from other sources. They are cool-growing clones, and a rarer hot-loving clone of this same species.
I`ll address Michael`s letter here, he points out the vast variability within a group of plants from multiple offsets taken from the same 'mother', I keep saying you can observe super-fast 'evolution' at work in Aroids!

Good Growing,
