  Re: [Aroid-l] Temperature requierements for Helicodiceros
From: Christopher Rogers <crogers at ecoanalysts.com> on 2010.01.28 at 18:31:33(20521)
Greetings, Bernhard!

I know that some people have grown this plant in warmer areas by putting the
tubers in the refrigerator for a few months.

Here in California, my Helicodiceros and Dracunculus started coming up in
the end of December. Here we have a Mediterranean climate. In fact almost
all of our invasive weeds here are Mediterranean natives: Avena, Hordeum,
Vinca, Lolium multiflorum, Taeniatherum, Centauria solstitialis, Centauria
diffusa, Carduus pycnocephalus, Carthamus . . . just to name a few. We have
hot dry summers, with temperatures in the 40s degrees C. In September and
October the temperature begins to drop. By December we are having our first
freezes. My Biarums were out in September and all my Arums (I have eight
species) and Ambrosina bassi have at least the first leaves up by November.
We have cool to cold wet winters, and the Helicodiceros is usually in full
foliage by end of February. I get my first blooms in April.

I hope that this helps,

Christopher
