That was how I got into dawn redwoods. Was reading about a giant sequoia in Englend, and thought it would be cool to grow one myself. Never considered they'd grow outside PNW. Reading around, it sounded like dawn redwoods grow a good bit faster, and are still giants, so I'll hopefully get to see them look impressive before I die.
Yep, dawn redwoods were my number 2, but from what I could tell were considered less threatened than the Sequoias are, so decided to go for them. It's interesting because these things actually have a pretty large range that they can grow in as long as they avoid super frigid winds early on, there's just no real natural way for them to extend outside their primary habitat.
For reference, I'm in upstate NY, finger lakes region. My specific microclimate has some pretty intense winter winds (and winds in general) but we also get a butt-ton of snow, so I'm hoping I can bury it in snow/box it in during the winter and get them to last long enough to survive the winters.
If I can repeat that I'll probably be able to spend the rest of my life planting these suckers around the area, given how many of these seeds I have now.
