Oops! Looks like I misspelled it. Here it is on line. 'Arisaema taiwanense J. Murata. Christened the 'Queen of Arisaemas' by Dan Hinkley of Heronswood Nursery in Washington, this is indeed an exceptional plant ...'
The original plant was a hitchhiker on a plant that I bought about 20 years ago at a plant sale at UC Sacramento. For years I cursed the nasty week that kept popping up in my garden. When I moved to Seattle, I was at a lecture and it was presented as a rare variety of Arisaema! lol I immediately went home, found some babies still trying to survive and they have been cherished ever since. Ever had this happen to anyone else?
