I think the app was right, a Juglans regia.

Does it get walnuts? The leaves look a little too rounded at the end to me for a walnut, but if that fruit turns into a walnut, then I would say English walnut, it has fewer leaflets and they are larger and rounder than black walnut.

Definitely a variety of walnut. We have many black walnut trees and your fruit is smooth as opposed to ours which are a bit fuzzy. Inside that green fruit is the walnut and inside that is the seed which is the nut we are familiar with. English walnuts are MUCH easier to harvest. Our black walnuts require a dedication I just don't possess! Walnut trees are beautiful and if they have the space are large and gracious.

Thank you!

Pink, we've not gotten this far in the development of fruit stage yet because of the birds. This is all new to us having the fruit look like it does! So I guess in answer to your question, we've not had walnuts before, but if the birds would leave the tree alone, we might have. New territory here.

DLM, good to know about your experiences. I would not have throught that a walnut would be hidden inside the green 'wrapper'! I've not seen one in person before. It is a large tree that we have to trim every year. It grew from a snowed on trash pile from our neighbor that a bear dragged into our front yard. Spring came that year and under the trash pile was a something growing and we let it be to see what might happen.

Thanks Jinx. The green fruit really threw me off! I thought that the app must have mis-IDed it.

I guess it *is* a walnut tree, after all! Yay. I'm happy about that!

It looks like a walnut, but it is decidedly strange to have a walnut tree and not get walnuts. That is, I'm surprised that birds would be able to eat all the fruit to the point where you got no nuts.

But yes, the walnut nut grows inside of a green casing. The green fruits drop from the trees and then dry up, turn black, and split to reveal the nut.

This site has a pic of the nuts and casings in various stages of this process:

Definitely a walnut. I would lean toward an English walnut because I think black walnuts have a slightly narrower leaf. We had three huge ones when I was growing up.

maddilee, oh, that's a good informative diagram there! Yes, learn something new all the time! Thank you for sharing it.

cawaps, odd as it is, this is the most developed fruit we've had to date. We have gotten as far as the fruits getting to be almond sized, then the birds come and eat them all. Miraculous we got this one so developed. It's exciting, even though it got cut down by accident. Dh is still upset he didn't see it before he lopped off the branch.

I've shared with him what you've all said, and he's extra excited to know this is indeed a walnut tree. He's hoping we get more in the years to come, with a few lasting long enough to be ready for him to eat!

My experience with trees getting stripped is that other critters, land critters, take more fruit off trees than birds. I have 2 peach trees, an apricot, and plums -- I got exactly one peach from all those trees. The weather hasn't helped, but one peach loaded up and that was the one we got the one peach from.

Mm - I love walnuts! My aunt in WI has an English walnut tree in front of her house and several black ones in back. I don't think she's ever harvested any, tho.

How old is the tree? Some trees need to get to specific stage of maturity to fruit. I have a Macadamia tree that did nothing for years, and now produces lots of nuts.

carolb,

The tree is 10 years old. Perhaps in years to come, it will produce more and there will be enough for birds and us. I can't imagine having a macadamia tree on site! I love those.

I'd suspect squirrels not birds.

Macadamia nuts are reportedly REALLY hard to crack. True, @carolb_w_fl_coastal_9/10? What's your method?

Back on walnut trees, a friend o mine bought a house last year and was overwhelmed with walnuts that she had to clean up from the lawn. She couldn't even enjoy them, since she is allergic.

At the Tudor house I grew up (and married) in, there were a dozen or more English Walnut trees. The squirrel ate more of them than we did.

Be glad you don't have Black Walnut trees. Our house sat half way up the hill, in the middle of three acres. It had a curvy main driveway and a straight second driveway that went to the lot next door that my parents also owned. The Black Walnuts that fell in the grass did not roll very far, so if I was bored, I would roll them down the straight driveway. Even the squirrels didn't like taking the time to eat many of them.

It's true - macadamias are hard as rock and almost perfectly round - they'd make good bullets 😄

I bought one of these:

Before that I learned a clever hack from YouTube, using a slice of pool noodle and a hammer, but that got old pretty fast. The nutcracker is much more efficient.

Black Walnut trees also tend to kill trees in their vicinity. Something about a toxic sap that they give off through their roots. Most likely a defense mechanism to ensure their share of water. We have one in a corner of our yard. Too big to take down, but it has killed the trees around it.

Jojo, Black walnuts release juglone. All walnuts do to some extent, I believe. There are shrubs and plants that are resistant: Amelanchier (Serviceberry), Physocarpus opulifolius (Ninebark), many maples, fruit trees like cherries (my mother made the best sour cherry pie from our cherry tree under the walnuts), plums, and peaches. There are lots of others, too. Some azaleas as well.

The trees contain the chemical in their leaves, fruits, and roots. I have read that even their branches/twigs can release it when they fall.
