Hardiness of Pinellia cordata
John Grimshaw (Fri, 05 Jun 2009 04:46:41 PDT)

Pinellia cordata 'Yamazaki' has never persisted in the open ground for me in
England, although small tubers will occasionally reappear next spring. I've
always thought that the shoots get eaten by slugs etc, rather than frost
being the principle killer.

I grow the same Pinellia cordata clone ('Yamazaki') as Ellen, and have
found that none of the ones that I plant intentionally persist for more
than a year or two. However, the volunteers that fall out of pots or get
moved by the local vermin have found several sweet spots in the garden,
purely by chance. I have one such clump with a couple of inflorescences
open as I write. There are numerous instances of the odd leaf here and
there, too.

I winter over the ones in pots the same way as Judy, either in the
freezing garage or under the bench in the cool (38F) greenhouse. They
seem to be doing *very* well in the mild spring we've been having. There
was a quick hot spell a month ago to get things going, and warm to
downright chilly (39F last night, June 1) since then.

I vote for trying a few outside in NJ, but find some vermin to plant
them for you...

No, it hasn't been long-term hardy here - the younger ones tended to
live
a couple of years and then disappear. The only ones I have now are in
pots.
