[Arisaema-l] What is this Arisaema?

[Tony Avent]

Charles:

I agree that a Taiwan origin is unlikely for her material.

Gusman book says grapsospadix has a distribution of "China: S. Taiwan, also reported in Fujian (FRPS).... in cool and shady woodland conditions, at low or medium altitudes". I guess 5,000 feet is "medium". No way to know where hers came from I guess, but I doubt if she gets plants from Taiwan, does she? There is all that hostility by mainland China which considers Taiwan a rebel breakaway province. Fujian is the part of mainland China closest to Taiwan.

Charles:

Our ground was frozen this winter for several weeks, so that we couldn't even dig in the ground and our plant of Arisaema grapospadix came back fine.  There could be some difference with elevational collections.  Our plant came from 5,000' in Central Taiwan.

Tony: So you leave it outside without any protection from freezing or snow and it survives OK? The tuber did fine for me underground over the winter, but I don't think the ground freezes, so the tuber is not subjected to sub-zero temperatures.

Charles:

It looks like Arisaema grapospadix to me.  You can see the photo we took of it in the wild in Taiwan at http://gallery.plantdelights.com/Taiwan2008/60774_G

It has been hardy here, but no flowers, which it normally does in late winter.

Sold as Chen Yi A-144, Arisaema aff. grapsospadix, and it looks like the picture of that plant in the Gusman book. But the only thing you can depend on from Chen Yi is that the plant is probably Chinese.

Put the bulb in the ground April of 2010 and it just came up June of this year without infloresence. Nice shiny leaves and is unlike other Arisaemas I have.

If it is in the Anomala Section, it would be evergreen and according to the book won't like it in my garden when it freezes this coming winter. Gusman's book says they should be cultivated in pots. But it is from the more northern extent of plants from that Section, unlike some from Indonesia and Malaysia.

Anybody else grown the Chen Yi A-144 or can you ID the plant from these pictures taken today? Is it a death sentence to leave it out in the garden over the winter? It isn't that cold in the winter here in the southeastern USA but it always gets below freezing for some period, particularly in January.
