Selecting Scionwood

[markshancock]

I believe my tree is a Purple Leaf Plum (Prunus cerasifera) and it looks like @speedster1, @SteveM and @Matt_in_Maryland have all tried grafting fruit into one before

Purple Leaf Plums (Prunus cerasifera)

What are the grafting options for purple leaf plums? My sister has 5 purple leaf plums as ornamentals and they are very pretty in bloom and throughout the summer. They are about 10 years old and have produced small 1" fruit 3 of those 10 years. Since its Prunus can asian plums, pluots, peach, or apricots be grafted to it? I’ll have extra scionwood and she wants to see if anything usable would grow on those trees.
