My parents house got messed up pretty bad during hurricane rita. They sold it as is and moved to another house. Then house they bought didn't have any damage from the hurricane, but lost all the trees in the backyard. My dad had a friend that owns a nursery and gave him a handful of trees and bushes to plant at the new house. We'll my dad plants them, but only vaguely remembers what he planted. One of them he knew was a citrus tree, but couldn't remember what kind. When it starts putting out green fruit he says, "oh it must have been a lime tree". Worst limes you ever tasted, but the first couple years there were only a handful and he picked them all as they showed up. Third or fourth year there were about a hundred during the summer. They had a barbeque and he was telling a neighbor about this horid lime tree he has and doesn't know what he's going to do with it. The neighbor says he has one exactly like it, but it's a lemon tree and they don't turn ripe till Novemberish. Consequently my parents have an awesome lemon tree.
