I recently noticed that the gorgeous trees at the Kapolei Regional Park (Oahu) look like ficus. I started shopping for ficus but then realized I didnÂt know what the heck I was getting into. If I have room for the canopy will the roots do harm? Does anyone know about the varieties or where to read up on them. (The web only seems to give me hits on indoor trees and fruiting figs) How fast will they grow? Where is a good place to pick up a couple in the 6Â size range?
