Hi Dominic,.
What type is considered to be difficult, is difficult to answer, because it is always on the conditions.
Considered very difficult to impossible but pendulus and bufo. But even people with green thumb to have managed that.
To bufo I have consulted once in the aroid mailingliste, because a friend had heard, that there should be someone on the scene, holding home bufo on the windowsill.
(Which showed the request, do I copy below in the post, please the translation function, which has implemented Stephan here in the Forum, use, or ask the babelfish (
http://www.bing.com/translator/ ).-I don't currently have time to translate it all...)
I own some bufo are since the spring in the winter garden, where there is of course also more than 24 ° C in sunlight, but so far they still grow and make a new page at the time. Whether they come well over the winter and continued to hold in the next summer, when it will again over 24 ° C, are must see.
rhizomatosus, lambii and hewittii are certainly difficult, but some can hold.
Generally you should always try to get out, as are the conditions at the Wildstandort - but beware, that does not mean that that are optimal and it; just imitate that, are out through simply only conditions, under which the type survives and reticulate and these conditions can be sub-optimal for the art or the growth of the art.
Since I was not clear, that taurostigma in Madagascar probably under conditions of dry and rainy seasons grows, have lost I my first 'White Veins', that I they like titanum or hewittii (immerfeuchte tropics) after docking have kept slightly moist. My new is now dry in the living room closet!
Species immerfeuchten Indonesian tropical falls me a ad hoc still that decus-silvae for me is less stature, like gigas. But that may be reversed for other...
Happy growing, Bernhard.
P.S.: So, here's the mail from the aroid mailing list to bufo (highland):
(P.P.S.: just to clarify; there are still one bufo lowland, which probably cope with wäremren temperatures.) (But which hardly anyone, since she has, so I know much, only for very much money in Asiatic Green is to get.)
Amorphophiles,
quite some time ago I sent a question asking growing advice for
Amorphophallus bufo (Cameron Highlands, Malaysia).
I got only one reply and that what off list from Pascal Bruggeman from
The Netherlands. And he is in deed the one who grows bufo on a window
sill, a thing I heard rumors about before.
He did not mind forwarding his growing adjourned to the list and here we
go:
"the main reason in failing with bufo is that it is grown TOO HOT." So
No, they should need be grown warm! Bufo grows in the Cameron Highlands
and the day temps will not exceed much above 22-24 C. night temps can
easily drop to 13 C. So very inmportant is to keep the compost evenly
moist, I have lost too dry and then 2 plants by letting the compost get
give them water, roots of this species seem to rot easily with
fluctuating moisture content and so water it from the sides of the
pot.
Bufo doesn't mind dry air, it does however mind fluctuating moisture
levels of the soil so I have to admit I grow it on a window sill with a
plastic bag around the pot so there is no evaporation from the soil.
Regarding the potting mix I grow them in, it is a mix of fibrous peat,.
chunks of peat and bark. It is a commercally availble mix as in NL
"Jongkind No. 7". But as with most cultivation, each growing condition
requires a different mix, it could very well be that what does well in
my situation will not in yours. But in the wild you can find them in a
crumbly clay like soil with the top of the tuber and some of the roots
in the humus layer. Usually these growing conditions are very hard to
duplicate in cultivation so I always try a "normal" mix first. And this
time it was OK, Jongkind 7 is humus rich, airy and moisture retentive.
Regarding the plastic bag, I either put the whole pot in a plastic bag
and tie it cling film around the stem or put on the pot when I pot the
Tuber up. Once it comes up I simply make a small hole to let the shoot
through. Purpose is to minimize the evaporation from the soil to the
only water loss is for growth and through the leaves. It means that
instead of watering it twice a weekI have to water it once every 3
weeks. This creates a more stable moisture content in the put. In the
wild the moisture levels are also very constant because of the buffering
capacity of the forest floor and the dead leaves on the soil also
prevent evaporation from the soil. I basically use cling film to replace
forest leaves....."
Thanks to Pascal again via this post (just in case that he's still
reading the aroid-L).
Hoping that this might be helpful for everyone who wants to grow species
from similar habitats.
Happy growing, Bernhard.

> Aroiders,
can someone give some more advice than the general
(free draining potting mix, warm growing conditions, fairly moist due to
the origin - Malaysian highland mountain rainforest)
to grow Amorphophallus bufo (Highland) .
All I heard so far is that it is pretty difficult; on the other hand the
are rumors (well a single one) that it can be grown on a window sill
(yes, bufo, not a misslabled konjac or something similar...).
Looking forward to any suggestion.....
Best, Bernhard.
