<p>Esperanza and Irwin have discussed horticulture on the east end before. Tree collecting, while related, is a bit different. In the early 70's Alfonso A. Ossorio, the artist and sugar magnate, began amassing thousands of rare specimens of evergreens on his 60-acre estate, the Creeks. Horticulturists and tourists have come from all over the world to visit his arboretum. Ben Heller, the real-estate investor and art collector and dealer, also collected rare and beautiful trees, and Warner Leroy filled 60 acres in Amagansett. More obsession than hobby perhaps, but a fascinating peek into a world not often discussed.</p>
