It's a beauty, and you are very fortunate to have this in your garden. What a story it could tell. I attended a gardening conference in Gainesville last year, and some of these old palms are being documented through old photographs, what was growing nearby, landmarks, etc, etc., and some of them are known to be a couple hundred years old -- at least.
Awesome photo's - thanks for sharing. Kind of new to FL and palms but that is by far the tallest I have seen and I am in Pensacola where people have been planting and meddling since the 1500's. I wonder what the record height is?
