Various Minimum Temperatures

From: Paul Tyerman ptyerman at ozemail.com.au> on 2001.05.28 at 18:17:27(6587) Howdy All, Is there a listing somewhere that of minimum temperatures required by the various species of Amorphophallus? I am trying to find out which are the tropical varieties and which will take frosts etc. I know that varieties like bulbifer and konjac are fine in frost, but what others are? I'd like to grow as many of these as possible as I find them utterly fascinating (well actually... them, Arums, Arisaemas, Biarums, the list goes on) I am also after similar temperature information for Alocasias, Colocasias, Typhoniums and Xanthosoma species. I was reading back through some of the stuff that I've saved regarding aroids and noticed that one person in Zone 5 mentioned that Typhonium giganteum was hardy there (I assume dormant in winter?) so there are obviously some varieties that take the cold. Basically I'm just trying to find out exactly how far I can let this addiction take me before the aroids own the house in winter and "I'm" sleeping outside in a pot!! . I'm only just starting to find out that the certain species of Philodendrons, Typhoniums, Alocasias, Colocasias are really something I can actually think about growing here unprotected. I'd always thought of them as being "tropical". Thanks in anticipation of any information or leads to any information. It may be better to email me directly rather than clogging up the list with unwanted information for those people who do not grow these things. I hope no-one minds me asking what some would regards as such a "general" question. Cheers. Paul Tyerman +More Canberra, Australia. USDA equivalent - Zone 8 mailto:ptyerman@ozemail.com.au Growing.... Galanthus, Erythroniums, Fritillarias, Lilium, Aroids, Irises plus just about anything else that doesn't move!!!!!

Here in Raleigh, NC, USA, USDA-zone#7, the following are also cold hardy: Amorphophallus napalensis Amorphophallus odoratus I'm testing/will be testing the following for cold-hardiness: Amorphophallus henryii Amorphophallus kisusianus Amorphophallus albus > > I am also after similar temperature information for Alocasias, Colocasias, > Typhoniums and Xanthosoma species.

It is extremely cold hardy, as is Typhonium roxburghii (formerly T. diveracatum).

I grow T. divericatum as a 'ground cover' in a very large potted Crinum asiaticum. The pot is in full sun and setting in a deep saucer of water in summer and MUCH dried in a sunny window in winter. Grows like a weed. Blooms off and on all summer. Jim W. +More Dr. James W. Waddick 8871 NW Brostrom Rd.

From: Paul Tyerman ptyerman at ozemail.com.au> on 2001.06.13 at 14:59:56(6695) Howdy All, Just a quick note to say Thanks for the information regarding cold-hardiness of various aroids. Has been a great help to me, particularly the information on the IAS site (which I didn't know about). Thanks to all who responded. I now know there are far more aroids that I can grow here outside . Now I just have to find them. Out of interest.... what is the minimum temperature that anyone has grown Amorphophallus paeonifolius outside without frost or cold protection? Is that with Snow cover or not (I think I've heard that Snow cover actually helps insulate and isn't as bad as just plain cold?). Thanks again Peoples. Cheers. Paul Tyerman +More Canberra, Australia.
