I have one of these fruit salad trees. I bought mine from Raintree nursery
Combination Fruit Trees - Raintree Nursery online ten years ago. Mine is a plum, apricot, peach and nectarine. They are around $25.00 and get shipped right to your door at around 4 to 6 feet. They taste great and produce really well. I have this plant at my Santa Barbara house. They have many different types of combo plants.
