We have 4 trees at the back of our section, 3 are covered in pink flowers at the moment, one was laden with white flowers, branches dripping white petals, which has now given way into fresh green leaves. I think the white flowered tree is a plum (I'm hoping for elephant heart) and the pink are peaches. I've also found lots of peach stones while digging over the garden beneath the trees.
Two of the trees are planted quite close together and are quite large. If I can work out how to protect the fruit from the birds, I'm expecting a big crop.
Flowers collapsing, having done the hard work attracting bees, tiny furry fruits appear at their bases.
