I like unusual plants and one odd one, that is very popular, is called araucaria araucana or Monkey Puzzle tree. Doing some research for a friend I stumbled on an interesting history of this unusual plant. I have mentioned this plant in a previous posting (from one of my former ghosts) but learned a lot from this site. Check out the Monkey Puzzle Avenue of Bicton Agricultural College in England. Nature has a lot of amazing life forms.

"Their incredibly ancient lineage makes them living fossils, and similar to Ginkgo trees, they lived alongside dinosaurs. Its long, thin, spiky branches were a natural defense against the grazing behemoths."
