Hi All,

Sorry to need to resort to asking here, but with the info I was given, I can't find it by web search.

I saw this perrennial planted in two different zone 5/6 gardens this weekend (so not tropical) and one gardener said it was "Pit...something". It's about 2 feet tall, with huge rounded foliage. I was told that it didn't tolerate any sun and spread by runners, but was easily controlled. Any ideas?

Thanks!
