fruit salad trees

I bought and planted four trees at the nursery on Friday.  One peach, one apple, and two fruit salad.  Oh, but what is a fruit salad tree?

On the left in the first pic, is a peach tree.  But look closely at the leaves and you'll see three different types.  It is a peach tree trunk, with two different types of peaches and one type of apricot grafted on.  It also has a nectarine branch and a plum branch, but they look pretty much dead so I'm not expecting anything from them.  So one tree, three different types of fruit.

The fruit salad tree in the second image is the one on the right.  Cherries.  Three different types that will have consecutive harvests.  

Now we just wait two years and we'll be swimming in fruit.  In all likelihood, we'll be moving in 2-1/2 years and we won't see these grow to full maturity.  Planting these is really for experience and for fun, so when we move into something a bit more permanent I'll have the experience to plant a real orchard.
