What is this?

Looks like an unripe fruit or nut from a tree. How big is it?

BRAINS! No. I do not know what it is. It looks like a hybrid, of a mango and gourd. I would bet Gourd. So you may want to take it to the nearest School as a Gift to the Science or Biology Teacher. They will figure out what it is.

Very interesting...are you going to cut it open? We once had "cucumber balls" because they tasted like tough cucumber...but as this mystery vine grew it was a cantaloupe we did not expect...just a seed from the compost! Try a local extension office, College, or farmer's market for some insight!

Hello I believe this is a Osage orange.

Please have a look here at the link below —to compare to your sample.

Hope this helps.

It's definitely Osage Orange. There was a Sept. 2000 internet post of an old Pittsburgh Post Gazette article, featuring this 'fruit", that squirrels love. It can be deadly to cattle, who have tried swallowing the fruit, and blocking their airway.

It's reputed to drive away insects.

Where do you live?did you get it in your area, outside some where? At market? Looks like Osage Orange to me too,only the seeds are edible Here's great facts on it https://www.wcpo.com/news/our-community/features/9-cool-things-about-osage-oranges

Thank you! It absolutely looks like my picture. I appreciate the time you took to help me.

we call them hedge apples in Missouri

Osage orange/hedge apple also sold as a mouse repellent in our local grocery stores; I put a couple in bowls in my pantry every fall.

It is a hedgeball from a hedge tree. You cannot eat or do anything with them that I know of. The trees make good hedge post for fence posts.

In Texas we call them crab apples. Deer like to eat them.

Yep that is the fruit from a Bodark tree otherwise known as in Osage. There are native to Texas. They were introduced through the mid west to control erosion and act as a Natural fence for livestock. The wood of the Bodark is so dense and hard once it dries It is impossible to work with.

it is beautiful ! cant wait to find out what is it
