Did you intend to post a pic? Location could help too.

if no pic... how about at lst a location.. big city name

I am in Louisville, KY. I was just out walking in the garden and these were on my pant legs.

In my garden this would be from Circaea lutetiana. But I have no idea if that would grow in your location. Other species produce similar fruit. Can you go out and find the plant they’re coming from and give us a picture? If they’re getting on your clothes you must be walking past them.
