So my neighbours have this fruiting tree, which is growing into my garden and it has a huge amount of fruit on it. It seems a waste to not use them if they're safe. I'm asking here what type of fruit are they and are they safe? The neighbours aren't exactly the most pleasant people to ask what the tree is, hence why asking here.
I've been doing some digging and I think they're greengages. I'm in Ireland in case that helps narrow down what can grow here in terms of fruiting plants.
Thanks for the help!
