Re: Temperature requierements for Helicodiceros

I had some of these for about 5 years that I had imported from somewhere in
France maybe 8 years or so ago and I can tell you that they did not like
being in my basement under grow lights where at night when the lights are
off it will get to around 50F and sometimes lower.  They produced offsets,
but never flowered so I sold them a few years ago (same with Dracunculus
canariensis by the way, although this one did flower a couple of times). 
The same conditions allow many winter growing bulbs from South Africa
(Boophane, Brunsvigia, Gethyllis, etc) and South America (Paramongaia, some
Rauhia, etc) to grow and flower so it was just these guys that did not like
my conditions......way too cold in zone 6 to stay in the ground here (lows
to -5F (-20C) on occasion).  I guess they just want to be outside in the
elements and feel the temp swings, humidity, etc.  Best of luck,

Bernhard,
I am certainly no expert when it comes to this plant, but I do have a few
in pots, so I will share what I know!  Here in Tennessee, USA, they start
growing in December and die back in hot weather, but I think they last
until June or July.
My pots were under a potting bench, getting almost no light and only a
little water dripping from the pots above.  I pull them out when I notice
them starting to grow.
Mine have never bloomed, however.
They are in a greenhouse that gets down to about 50F (10C) at night an from
50-100F during the day (depending on outside temperature and sun).

Aroiders,
from the
temperatures and seasonal rainfall on Sardinia I guess that
Helocodiceros grows from late Sebtember to April or May with the maximum
of rainfall in November and December and temperatures down to 8 °C (46
°F) in December to February.
I would
like to know, wether the low temperatures in the growing season are
neccessary or if Helicodiceros could be grown (and flower) at higher
temperatures as well.
Looking forward to
any comment,Bernhard.
