Sorry! I knew we were still "in the Amazon" at that point, because it's just one of the cutest monkeys I have ever seen. Made its impression on me :) Oh, and if their cute faces don't get you, they purr like a cat. Oh my! Here is a link that might be useful: isn't he adorable?!

Great clump! I think Monkeys would really like this one because it looks like a ton of bananas :)

You've got the genus right, Araucaria, but not the species. Your tree is A. bidwillii, common name bunya-bunya, called monkey puzzle in Florida. In TN, where I live, locals call china fir, Cunninghamia lanceolata, monkey puzzle. In fact, the so called champion monkey puzzle here, located at the Governor's Mansion in Nashville, was mis-identified as such by the state arborist for years, but it was finally corrected. True monkey puzzle struggles mightily in TN, and you would have better odds of winning Power Ball than having a monkey puzzle live, never mind thrive, in Florida. I've got a A.b. in my cold greenhouse, that I bought at a well known nursery in FL as monkey puzzle, and there was no way I could convince them otherwise LOL. To your original question, yes it will grow a new leader, probably several. You may need a bucket truck to trim it to one leader, because although the foliage of A.b. isn't as sharp as A.a., it is still plenty sharp enough, especially on juvenile trees, which is what you have. Google to see what a mature tree looks like, I've seen juveniles in FL, but not adult trees, but that doesn't mean they don't exist there. BIG difference between the two. I sure wouldn't want to mess around the tree on a ladder.

Some sort of weedy allium, maybe Allium canadense, wild garlic.
