Double flowering plum
I have three double flowering plum shrubs. Two have been in place since before we bought the property (9 years ago), the third was put in about 6 years ago. I don't know the cultivar name but all are what are generally referred to as "double flowering plum". I assumed that meant that they are purely ornamental. However, this year the younger one has fruit on it! I have never seen this before. Is it edible?
