I live in Melbourne, Australia. I just recently bought a new house and in the backyard of this house there are 3 plum blossom trees (at least that's what I was told they were by the estate agent). The tree had bright pink flowers when it was flowering in spring and now it is bearing fruit and they certainly look like plums. The fruit started out being light green on the outside and a lot of them are turning dark red which I am assuming is the colour they turn when they ripen. I am attaching a few photos of the tree, leaves and the fruit. Could someone please help me identify the type of plum blossom tree it is and also more importantly, is the fruit edible?
