  Gonatopus boivinii
From: Masaki Yamagata <yamagata at mahoroba.or.jp> on 1998.05.03 at 20:11:35(2076)
Hi all

I had Gonatopus boivinii, but have not bloomed heretofore.
What will be necessary to bloom?
And how will you let it propagation ?
Please teach me!

If anyone has any Gonatopus boivinii they want to thin out and get rid of
please email me and we will see what we can work out.

The extreme dry period here has enabled many of our plants of Gonatopus
boivinii to set seed again.[I think]
Last year I found one infructesence, but was to late to get a photo. These
took a long time to germinate, only coming up a few months ago.Now with my
handy 'digi-cam' I hope to get several shots of fruit forming on this plant.

Subject : [Aroid-l] Amorphophallus Gonatopus Boivinii

Dear Steve,

First off, it is not a species of Amorphophallus, but it belongs to a
seperate genus of around 5 or so species that originate in S. E. Africa.
In Florida, G. boivinii is considered by most growers to be an invasive
pest, as it seems to spread everywhere in and around the greenhouses or
growing benches. Like Zamioculcas, to which it is related, it grows easily
from fallen or dropped leaflets. In Florida I have seen two 'forms' of
this plant, both SAID to be G. boivinii, one has mottled petioles, and so
has been called the 'giraffe knee' plant (because of the obvious geniculum
or 'knee' half way up the petioles), but the other is all-green in color and
can grow to about twice the size of the former. I don`t know if the two
have ever been carefully compared to each other to know for certain if thay
are the same species.
It can be left growing all year, or dried off slowly and stored in its pot
over the cool/dormant season.
In Florida it is almost impossible to kill this very hardy plant.
I hope this informatuion is of help.

I'll ditto the part about G. boivinii being invasive. Every leaflet blown
off by wind and into leaf litter among plants among my oaks became a tuber
and then

I donā€™t think ill have to worry about that in central Indiana zone 5 hehe.
So in about September just start withholding water until it crashes?

Just move to Phoenix. They die quickly here.

I don't think you can go wrong with this one no matter what you do.

I'm also far enough north to have no fear that Gonatopus will survive the
winter outdoors, so it's been in my small greenhouse for years now. It's not a
weed for me - in fact I like it - but it is amazingly durable, and surprisingly
sneaky.

I've never had it set fruit, despite having several clones, so I know the
little ones must be from leaflets that rooted, but I don't understand how the
leaflets get from a low shelf on one side of the room to a high shelf on the
other. And I don't understand how they can thrive both in rock-hard soil I
haven't watered for months and in a pot in my carnivorous plant tray sitting in
standing water. But they do.

As long as it gets some water while it's in active growth, and you back off on
the water when the leaf starts to fade, you should be OK. The leaf will fade,
eventually, on its own, but mine do not pay any attention to the seasons
outdoors - I've been waiting for many months for a couple to go dormant so I
can send them to someone I owe.
