A thanksgiving day trip up the snake river to Heller bar revealed a tree that I've never seen these parts. Osage Orange (Maclura pomifera) is a common tree on the great plains where it was historically planted as a fence row due to it's dense branching and tough thorns.
The fruit has a citrus & evergreen bough scent and a beautiful lime green color. It is common in the mid-west to bring the fruit indoors for the winter to repel spiders and insects.
I think they are beautiful lined on my kitchen window sill.
