Joe, You might try the Dawes Arboretum in Newark. They have a nice conifer collection. Jay

Both are hardy in zone 6. Cedrus libani var. stenocoma is definitely the hardier of all true cedars.

Dawes is close to you and should be your first stop. Spring Grove in Cincinnati has many Stenocoma and the Ohio State Champion also. The Stenocoma at Spring grove survived 1992 winter of -25 so they are cold hardy.

Sounds like a trip to Newark is in order.

Where would I BUY them?

Is Cryptomeria a push around here? Is it more or less likely to winterkill than the aforementioned Cedrus?

I don't believe Cryptomeria likes the intense heat of midwest summers. It's certainly hardy in zone 6 however. My advice is if you have to have it to water it very frequently and site it in a location where afternoon sun isn't present.

You can buy all your cedars from Gee Farms.

Here is a link that might be useful: Click Gee Farms Link for 2012 Catalog

Cryptomeria cultivars differs in their hardiness. You have cultivars selected in Sweden like Tateyama or Swedica or in Poland like Wladislaw Bugala which are very hardy and you have cultivars which have a lot of problems in wind and winter hardiness.Also you can have seed from the nothernst part of Japan, which is more hardy than from the South.
And at last you have selections p.e. 'Egmont' from New Zealand ( Cedar Lodge Nursery), which are selected for windy locations.

Dax, no cedars at that link.

Yes there is, click it and then click the link below that says:
2012 Mail Order Catalog

There are (3) hardy deodara's and, cedrus libanai var. stenocoma, in #1 pots.

You might ask why did I link you that way? The answer is because the next link is a PDF. This way you have access to their website, and their online plant catalog.

"Is Cryptomeria a push around here? Is it more or less likely to winterkill than the aforementioned Cedrus?"

Sugi is a bit hardier than all but perhaps C. libani var. stenocoma. But it doesn't look remotely like a cedar, so fails to meet your requirements ;-)
