In Missouri our native hedge is Osage Orange.Oregon Myrtle is another member of the Laurel family that grows here on the Oregon coast. It is a beautiful, expensive wood that is often carved and turned into bowls, art, and assorted other items. I haven't heard of anyone here making pipes from it, but I'm sure it would be possible.
I posted of photo of my newly acquired smoking bench a while back, carved from some rare large sections of Oregon Myrtle.

Here’s a tree cut down in 1954
My Amish renter has Osage Orange corner posts set as far back as 1919 still in service on our family farm.
But due to scarcity of suitable hedge posts I’ve just built a mile and a quarter of new fences using T posts and all large sucker rod line posts and corners.
Osage Orange are trash trees. Only the straightest ones are good for posts, most grow in old fence rows, and once cut the farmers keep the brush down.
It’s a beautiful wood, and I understand a few pipes are carved from it.
But it’s prone to cracking, and the grain isn’t spectacular.
