Caution,these fruits might be poisioness? You might want to look up on this species for more information.

I don't think osage-orange is toxic, and it's gross enough that I don't think enough of it could be eaten to do any harm...yuck !
I've taken seed from mature fruit, it IS a pain in the neck.
The best luck I"ve had is when I forgot and left a bag out all winter on my porch. The plastic bag leaked a nasty ooz (which only took a couple of years to come off the wooden floor), but the next spring I put on a pair of the blue nitril gloves and squezed through the slop sort of like separating pumpkin seeds from the pulp, but, alot nastier.
After there was a pile of more seed than yucky stuff, I put it in a sieve and rinsed it for ages under running water, then dried them on a cookie sheet.
I have quite a few seedlings going, I think they are neet little trees, but I do have to back you up on the seed gathering being a real pain-in-the-neck thing to do!
Did you know the trees were used in place of fence since they are tough, fast growing, and even cattle won't fight the thorns?
Also Native Americans made an orange dye from the roots, and I think they used the wood for bows.
One of my hobbies is wood carving, and from those circles I've seen some beautiful sculptures done from the wood!

Not poisonous, used to feed them to my horses all the time. Also, squirrels consider them a treat. Supposedly they repel roaches and other critters however.

I am interested in your mock orange seeds. I have some NC native plants alto they are not on your want list. LMK if interested. plantbug

DON`T HAVE WHAT YOU ARE LOOKING FOR BUT WOULD LIKE TO GIVE YOUR SEEDS A GOOD HOME PLMK

I've heard they're an excellent spider repellent..I heard..if you put one in each corner of your basement...no more spiders in the house. Next time I see some fruit..I'm going to do just that, as I can't stand it when the dang tarantulas try to come into the house in the fall, LOL! May just be an old wives tale, though. April
