Here is the picture.

Here is another.

Mmmm, I think that some cultivars of the japanese plum (prunus salicina) have pink flowers. Would be keen to try it myself (only have the European plum, P.domestica). Think it needs a pollinator though?

well its definitely not a satsuma. Looks more like an inter-specific.

You can cross out the following options, as I have all of them, and non have pink flowers:

Santa Rosa
Satsuma
Inca
Elephant Heart
Autumn Rosa
Weeping Santa Rosa
Luther Burbank Plumcot
Beauty
Burgundy
Jefferson Green Gage
Persian Green
Emerald Drop Pluot
Dapple Dandy Pluot
Flavor King Pluot
Mariposa plum

Good luck

Satsuma flowers are white...

Thanks

Makes me wonder if its an ornamental plum, I have one of those with pink blossoms. None of my non-ornamentals show pink ever.

Some of the pink flower buds that have partially opened up look like their pink tips are faded and the ones that have fully opened up look like they have lost their pink coloring altogether and they now look like your standard all white plum flower.

Would an ornamental still have a little fruitlet that develops when the flower petals drop?

Thanks for looking, I appreciate all the responses.

If it is a non fruiting plum, it'll give me a good excuse to pull it out and put in a nice peach or nectarine.
