Amorphophallus titanum question

From: Paul Tyerman <ptyerman at ozemail.com.au> on 2004.06.20 at 09:55:15(11635) Howdy All, A quick query if I may?.... Does anyone know the absolute minimum an Amorph titanum can tolerate in growth and also while in dormancy? In the wild, what sort of timing (i.e month of the year) do the titans have for flowering, shooting and dying down? Thanks in anticipation for any help. Cheers. Paul Tyerman +More Canberra, Australia. USDA equivalent - Zone 8/9 Growing.... Galanthus, Erythroniums, Fritillarias, Cyclamen, Crocus, Cyrtanthus, Oxalis, Liliums, Hellebores, Aroids, Irises plus just about anything else that doesn't move!!!!!

In the wild, what sort of timing (i.e >month of the year) do the titans have for flowering, shooting and dying down? > Howdy again All, I had forgotten about Deni Bown's wonderful aroid book when I asked the question. From her book I found out a lot of information, particularly regarding their natural growing conditions..... i.e there IS no particular timing as the leaf grows for 12 to 18 months and then has a dormancy for no "obvious" reason except if flowering. Flowering can take place at any time of year as can dormancy, so there really is no particular cycle apparently. All fascinating stuff!! I would still be interested in hearing what sort of experiences those of you who have or do grow the titan have had, particularly the absolute minimums that your titans have experienced (and either survived or been hit hard by). In captivity does there end up appearing to be any sort of cycle that develops, or is it still very much "random"? Or alternatively, do you impose a cycle by watering etc? I recall that Mr Stinky and Audrey II both flowered almost simultaneously which according to Deni's book should be pretty uncommon, so was that done through management of the tubers to encourage certain growth cycle's? Thanks in anticipation of any information you can provide. Cheers. Paul Tyerman +More Canberra, Australia. USDA equivalent - Zone 8/9 Growing....

From: StroWi at t-online.de (StroWi) on 2004.06.21 at 08:04:00(11640) Hi Paul, I keep my A. titanum here in cold Germany in a Wintergarten with temperatures down to 10 °C at some days. Some tolerate this, some do not; however I am not sure, if it is just the low temperate that kills some, since I loose titanum in spring, too, due to a wet rot of uncertain cause. Does it ever get that cold downunder??? Good growing, Bernhard. +More Dollbergen, Germany approx. zone 6/7 "Paul Tyerman" schrieb: > Howdy All, > > A quick query if I may?.... > > Does anyone know the absolute minimum an Amorph titanum can tolerate in > growth and also while in dormancy? > .... > Cheers. > > Paul Tyerman > Canberra, Australia.

Last year (or maybe it was the year before) the 3 Titans at Kew flowered one after the other. It was only about 2 or 3 years previous to that, one of them flowered before. +More Neil

From: "Clark T. Riley" <drriley at mypcr.com> on 2004.06.22 at 21:12:21(11655) I presume you mean temperature. In the case of my specimens, they barely tolerated one accident when they were left outside at near-frost temperatures. They didn't like it and sulked for almost 6 months, but eventually recovered. So I'd say somewhere around 2-4 degrees C is dangerous.
