When I lived in Jax, I was a member of the First Coast Palm Society and most of my palms came from other members and/or auctions. I still own my house in Jax, rental now, and am confident that I have the northern most largest and most mature Bizmarckia on the Eastern Coast. It's at least 20 feet tall now with a massive trunk. I had many A. Cunninghmaiana "Illawara" that lasted for years and one still alive for nearly 10 years now. Matt Encinosa in Fruit Cove was a great source with a beautiful garden. My most prized palm was a Caryota Ochlandra that grew to 20 ft in three years, but succumbed to cold shortly after. Still have L. Saribus, L. Decora, A. Engleri, a giant Mule from Frank and Elaine at Moultrie Palms in St. Augustine, P. Sylvestris, and many more of the 9a/b regular stuff. I thought zone pushing was tough then, but little did I know. I am not sure how active the FCPS is anymore. There is a beautiful garden of donated palms at what I believe is now Florida State College at Jacksonville with a mature Acrcomia totai all donated by the FCPS.
