Re: Versicolor or virginica was Spuria?

---

I'll have to make an effort to collect seed from the northern edge of
virginica's range for the seed exchange, if I can find them among the
versicolors. Considering the species is native from Lake Superior to
Florida, I imagine there's a lot of variation in hardiness. Assuming
that Flora of North America range map I linked to is correct, there
are populations of virginica native to USDA Zone 3a (-40°) in Wisconsin.
