Not peach.

Yes certainly not a peach. It doesn't look like a plum either. Looks like a pear to me.

I've had pears that took 10 yrs to start flowering. Plums and peaches usually bear by the third yr, or at least flower.

Plum. Has it flowered? It should have white flowers.

I would have to ask my mom if it's flowered. However, it's the only one we have so won't I need another one for it to actually produce plums, as they aren't self pollinating?

I don't think it's any type of prunus. Looks more like pomme (apple/pear)

I don't know much about fruit trees, but it looks like it has thorns, are they prickly?

Maybe, you can show again once it has leaves.

A closeup picture showing the buds might resolve this.

Looks like pear to me . Seems very thorny even for a pear . Looks more like flowering pear .

Those aren't thorns. They're fruiting spurs probably on some type of pear.

I was myself wondering if those were thorns or spurs.

Just checked with my mom. She says they are thorns and when the tree was smaller she would get so mad while mowing around it because they would "stick" her and hurt...lol. She says it gets green leaves in the spring but never "flowers". I'm still thinking it's a plum tree... I bought it in 2006, but can't remember!

We need to see what the leaves look like to be sure!

Can you show us the bark on the lower trunk?

Our wild plum trees get thorny looking spurs like this.

American plum sure gets thorny! I know on some of the jap/American hybrids (Superior, Alderman ect) they are budded onto American plum rootstocks. Just wondering if the scion perhaps died and the rootstock is what you have left?

Most definitely the photo shows this is not a peach tree.

could be Hawthorn...

or american plum both have thorns

Plum trees can definitely have thorns - Prunus americana is known for them. And there is a very big difference in a thorn versus a fruiting spur....fruiting spurs do not form sharp spikes!! Ornamental pears are also very prone to thorns but this looks more like plum to me.

Hawthorn thorns tend to be rather fearsome so doubt it is that. But posting back when the tree is in flower and/or leaf will help to confirm.

There are also some plums that have fruit spur's, I think weeping Santa Rosa is one

All plums have fruiting spurs. But as noted, there is a marked visual difference between a thorn and a fruit bearing spur - the tree in the photo has both.

They look like sharp fruit spurs to me. We grow hawthorns at work and the photo does not look like hawthorn. You ask if it is a plum or peach. Most definitely not a peach! Fruitnut could be right as sometimes callery pear rootstock can be very sharp with fruit spurs too.

I have to wonder if the top (scion) died and what you have is some sort of callery pear rootstock or American plum rootstock? The bark color is so light that it does look more like pear than plum. I would think if plum the bark would be darker in color. Just my guess.

Please re-post when in leaf and show a close up of the leaf.
