Monkey Puzzle Tree.

Nel is correct. Some further info.....it's neither a succulent or a palm or a pine tree either! Botanical name auracaria auracana aka Chilean Mountain Pine or Monkey puzzle and they're from the Andes. They're ancient trees from the dinosaur age.

I think the name is because even Monkeys can't climb them?

Thank you, Heather! I never would've heard of this plant otherwise.
