Which Tricyrtis don't die back?
I just discovered toad lilies at the NW Garden Show last week, and since then I've been a little obsessed. I bought an 'Ogon' at the show, and I've since ordered a 'Sinonome' and a Tricyrtis maculata.
I haven't found much specific information on this, but I thought that all toad lilies would die back to the ground in winter. Then I found this page that says 'Gilty Pleasure' doesn't die back in the winter. Are there other Tricyrtis that don't die back? I'm in zone 8.
