Fruit Tree ID

[Cubera]

Anyone know what kind of tree this is? Some sort of fruit almost tennis ball size. Old Vietnamese lady owns it, so trying to ask her probably wouldn't get far.

Kaffir lime?

[ralph7]

That's what google lens told me it was.

Horse Apple - Osage Orange - Bois d' arc

Looks like Trifoliate orange

but the ones I have growing here the fruits are only ping-pong ball size

might be a sub-species

They make good cold hardy rootstock for grafting other citrus on

Don't think so, all the fruit on this tree are tennis ball size or a little larger. I looked it up, and the pics they show are ripe fruits in a mans hand, and look ping ball size.

Download the app "Plant Finder", take a pic of the leaves and it'll ID it (not 100% accurate, but pretty high)..

After doing a search I agree with FishGuruOO who IDed it first

A Kefir lime

I never seen one before

[fishguru00]

I’ve had a couple of these kaffir limes before and the limes looked like that. I couldn’t seem to see a leaf in good detail. The leaves are used in a lot of thal recipes. I used them in soups and are unique in form, like two leaves in one. I couldn’t make out that pattern on the pictured leaves.

Late to the party but yes, Kaffir Limes. A friend's place in Hawaii has 20 different types of exotic fruits from all over the world and he has 2 of those. He used the juice of one for a fish marinade and I found it way too tart/bitter.

LOL, non local palette! Probably he loves the taste?

[LouReed]

He's Vietnamese who came here in the great asylum after the war in Vietnam. Lived in Lake Jackson then Houston since he was 8,but bought a place in Hawaii about 12 years ago. Yes, his palette is wide open for about anything, but Asian foods run strong. Watched him make what Vietnamese call a caramel sauce (sugar and water in a skillet until browned, then add a bunch of fish sauce. It'll run you out of the kitchen for the first couple of minutes, but if you stick around for the meal, you'll come to see the light.

With an IPhone you shouldn’t need to do that

Here's what my search showed. I'm confused. Same as Kaffi Lime?
Then this came from another app.

If you look close, you can see the tree has trifoliate leaves with winged petioles. This is going to be a roostock of Swingle citrumelo or Citrange. My guess is Swingle citrumelo, which is a cross of Ducan grapefruit and trifoliate orange. This tree has some leaf miner damage and starved of nitrogen. Swingle can have somewhat bumpy fruit and the stress of leaf miners and lack of fertilzer will misshape fruit also. Not a Kaffir lime. Kaffir leaves almost look like a double leaf, one after another. I would bet the tree froze and this is the roostock growing back. Swingle fruit carries the kerosene taste over from it's trifoliate parent. Best bet would be to regraft it.

Long time citrus grower. Before the freeze I had 35-45 citrus varieties and 60+ citrus trees.

[Yannister]

Terry knows his stuff.

Yes, 3 petal leaves.

Keffir lime has a single leaf that has a little fat section by the stem. Great seasoning by the way.

Looks like someone's freeze killed citrus grew from the rootstock. The fact the stock is fruiting means it must be 10 years or more old

[Cubera]

Makes sense, all her trees suffered damage after the last big freeze. She lost 2 other trees that had to be cut down.
Thanks Terry.
