When my mom, Mildred, and Tim's dad, Richard, passed away three years ago, we planted a fruit tree in honor of each of them. A dear friend had given us a gift card to do so. We decided on self pollinating fruit trees; they bear fruit on their own, without an entire orchard around them. Mom is a plum and Dad is a peach. (He always was a peach of a guy, really).
Recently Tim was given a fig tree from a fellow yardener and we purchased a nectarine tree to add to what we now call the fruit tree garden.
