I was going to say wild plum! We visited friends in Medford, and the wife took me out and around their property and showed me the different trees with the red and yellow wild plums. She said she always picks them and makes jam and things. I got to taste the fresh ones, heavenly!lsulenes said:I realize that Oregon is a long ways from Kansas, but at this time of year, something looking like that fruit and those leaves, would be wild plum, which does only have a pit and not multiple seeds. Cherries generally bloom in early spring and have ripened and been gone since June here except for the small wild ones. Just my take on what I'm seeing. I have no suggestion for the other one because I've never seen it.
