Outside your zone here in Zone 7b/NJ, but I think your biggest issue will be late frosts. I just checked and they seem hardy to Zone 4, but they are NOT happy if new growth has commenced in the spring and you have a freeze. they seem to prefer a somewhat less extreme continental climate. One year, mine had leafed out in April but were torched by wind and high heat in mid April. Probably best to select the common species nothing exotic as those will be less robust for you. Extremely fast growing tree, BTW!

maackia,

Last winter, I did extensive research on this tree and one source that made the most impact on me was from an old post I found right here on garden web from wisconsitom.

eta: of course this is back in the day before our zone upgrade.

My metasequoia came from a nursery in Michigan…

I’ve seen some decent specimens of Ogon in very sheltered spots in the twin cities. Mine died after a hard winter in my backyard. Same backyard has had species since 2012 but its not a great specimen. It’s taken a hit a few times. they don’t leaf out that early up here so I don’t think frost will be an issue.

With how much it costs to get your hands on a tree these days, I would make sure it will ”work” for you. unless money is not an object to you :)

This source claims z4. You could contact them to see if this was a typo.

Generally, these guys tend be a little on the high side with their zone ratings.

It was a low cost plant in a small container. After reading through the thread Bill linked to, I'm not at all optimistic about it. It's a seedling, so maybe that will improve its chances. On the other hand, besides our cold winters, I've got sharply drained soil that dries out quickly. It probably has one root in the grave. We'll see how it does and I'll hopefull remember to update the results.

Pennlake, that setting is pretty as a postcard.

If it’s cheap go for it! I was wanting a bristlecone pine and the wholesale nursery I have access to has them for sale for $600 dollars! $600. Inflation is out of control. swear a couple years ago the same tree was $300, which is still a lot.

Does Bristlecone do well in your part of Wyoming? I’ve tried it twice at two different places. Neither lasted for more than a couple years. Pines generally thrive on my sand patch, but not this one.

Yeah, they do fantastic here. Wish they were planted way more. There are some nice specimens here up to 40 - 50 feet tall. Lovely trees

Mac, put it in the wettest spot you have.

I have 2 .. the one in way back where it floods is MUCH bigger

Dawn Red also likes it MOISTURE, nearly as much as Bald Cypress. BTW, see those are also listed to zone 4. Of the two, I do prefer the DR, It's the growth rate

Johnson's Nursery's (WI) website usually has reliable information, and they rate DR to z4. Their plant profile on Dawn Redwood includes photos of relatively mature DRs in Wisconsin that appear to be doing well.

Dave, that is encouraging. I’m about 200 miles northwest of Johnson’s, and probably a full zone colder. When I was a young gardener i could easily convince myself that I could somehow make it work. I still like to do a bit of zone pushing, but I’ve been chastened by mother nature.

I really can't do wet. I’ve read in a couple different sources that once established, it will tolerate moderately dry conditions. The next question is what do they mean by

”moderate?” Anyhow, I hope that’s true; it’s the best I can hope for.

Z4b? Protected area? Piece of cake maackia.

Give it a location with a down spout in the vicinity. :-)

maackia, nothing to lose by trying, but I have both DR and baldcypress, and the later is just as satisfying and certainly hardier.

Yeah, from what I've seen up here I'd probably give BC a slight hardiness edge over DR. My Shawnee Brave BC has been going along fine without any damage for about 5 years.
