Plum or cherry?

[Containergardener]

Our neighbours have a tree that over hangs our garden. This year lots of fruit has appeared. The neighbour told my husband a couple of years ago it was a plum tree that never fruited, sadly he has passed away now and didn’t get to see it fruit.
Google and plant identifier is telling us different things but the fruit looks more like cherries to me, not quite golf ball size.
Any ideas? Apologies not the best pictures!

They look like plums to me. Lots of fruit is growing small this year because there's been no rain.

I'm no expert at all but I have a cherry tree and the leaves are longer than the ones in your photo I think? I think the stems to the fruit are longer too but it's difficult to tell.

I think it’s the same tree that we’ve got at the top of our garden. It’s taken us a while to identify the fruit, but we think it’s something called a cherry plum - prunus cerasifera, apparently. Very appropriate, as it does look like a large cherry and tastes like a plum!

Thanks that’s interesting I will investigate further! Will offer to pick it all for the elderly widow who was left behind, and hopefully can keep some that was hanging over ours.

It could be a mirabelle? They are small very sweet plums which you get in France. Delicious.

Looks like a plum. We've got masses on our plum tree for the first time, it was such a lovely spring. Poor tree is struggling with all the fruit.

Cherries tend to have longer stalks than that, so I'm guessing plum too. There are hundreds of varieties though, and some of them (as pp rightly say upthread) are quite small.

You can usually find out by eating one.

I think you might be lucky and find it's a Victoria plum! 😋

Loads of these trees growing by the side of the roads near me. They are all covered in fruit and appear to be tiny plums.
Planning on picking some to make jam, although they are so small, deseeding them will be a pain.
