Hi Dan, I am imagining (& hoping) that zone 7 is where all the south eastern & western species will come together & be happy. Ithaca certainly was not the place for that ( lancifolium did do well there) & apparently neither is the SE US for western species. Both ovatum & rivale are native here & albidum is pretty close by as well. Although there are what appear to be vastly different habitats around me, water (presence or absence) appears to be the defining thread. Perhaps I'm oversimplifying things, but I am about to find out. I should just check your website John but did/do you grow western T's with any success?

> A bit I can add re the discussion of T. decipiens: I received seeds which I sowed in my USDA zone 7a woodland in 2010. By 2013 I had 30 yearlings. In 2014, 15, 3-leaved plants remained. Presumably the losses were from voles or invertebrates, as I noticed no injury from too-early emergence, and the plants were healthy in appearance. Here they have emerged at about the same time as cuneatum. They are in always-moist, sandy loam beside a brook. The winter lows here reach the single digits Farenheit a few nights yearly, with typical lows around 20; it can remain below freezing for a week or more in a spell; the soil typically freezes to a depth of several inches and may remain so for weeks; winter is usually interrupted by warm spells with complete thaw followed by deep freezes. I believe the seeds originated from a collection in Boone, NC, which is above 3,000 ft. above sea level and I would guess is zone 5.
