The “Hedge Apple” production in my neck of the woods is very poor this year. Yes, I removed quite lot of Hedge trees, but I do not have any shortage.
I have watched squirrels & deer (& a few cattle) eat the Hedge balls.
The milky colored sap is quite sticky & will stain clothing (ask me how I know).
Hedge balls falling from the trees have cost me some opportunities while hunting deer.
Hedge balls are a blast to shoot (on the ground) with .22 hollow points.
I'm originally from central Alabama and Osage trees were very common. I live in north Alabama now and rarely see them up here. I never considered eating one.
There are a couple hundred seeds in each "apple" and a few hundred apples on each tree, and I saw someone selling an envelope of 10 seeds for a $! on ebay a few years back! I just don't think they'd have enough buyers.
