Diploid Arisaema triphyllum

[J.E. Shields]

Hi all,

As I recall, A. triphyllum stewardsonii is diploid, and as noted in Gusman
& Gusman, they are swamp dwellers.   Don Hackenberry
<donhackenberry at acsworld.com> has A. stewardsonii in his Fall 2003 list, in
case anyone is interested. I've already ordered a few from him.

Since I want stewardsonii and don't live in a swamp, does anyone have any
tips on how to grow these? Would they need as much water as Calla palustris?

Here in central Indiana, I assume we have the typical tetraploid A.
triphyllum triphyllum as the native form. Mine grow in a dry woodland setting.

I got a couple A. triphyllum from Gene Bush a couple years ago, and these
are turning into giant plants compared to the local natives I have not far
away. These large types still. have some foliage, whereas the local
triphyllum lost all their above-ground parts weeks ago.

Regards,
Jim Shields
