How hardy are hazel? The winters here in Maine can get a bit nippy with occasional daytime highs in the negative double digits, Fahrenheit. We had a solid week where it didn't get above 0oF.
Worth a shot, though. I'll have to see if I can find seeds. Until then, our native yellow birch would make a good substitute, color-wise.
(quote from Rodney)You can wrap wire around the shanks or plant honeysuckle if you want to make your own twisties.
I actually tried that a few years ago, but I think the wire I used was too flexible. Plus the trees I tried it on were still in the woods, so I only found one out of 4-5 that I'd wired.
