We have some nice looking specimens of Horstmann's Silberlocke Korean Fir, maybe 5' potted here at our garden center in Wisconsin. Not sure where their stock comes from. They are $100.
My sister would love to plant this in her yard, southern exposure in Minnesota near the Twin Cities.
Is she asking for trouble? I see that some info says zone 5, other info says 4b. I think she's probably in zone 4a.
She was wondering about success with using burlap. She did say it is not in a protected spot....like other gardener's, she often has zone envy.

If anyone has another suggestion for her that might do better....it would be a specimen in her front yard. She was also looking at a Conica Concolor Fir ....which I imagine might have the same issues for her, as she can't find one in her area.

If anyone knows a great source in the TC for her to find unique conifers, she'd be thrilled.
Thx!
