I live near a collage town where they have a big yearly festival called the 'Bois d'Arc Bash". If you don't know Bois d'Arc is yet another name for the 'horse apple' or 'osage orange'.
The Bash was started by the late, and in my opinion great, Dr. Fred Tarpley. He also wrote a book that will tell you more than you ever wanted to know about this tree. It used to be used to make living fences that were "horse high, bull strong and pig tight". Native Americans used the wood to make bows; thus the French name of 'Bois d'Arc'. The name of Dr. Tarpley's book is "Wood Eternal, the story of Osage Orange, Bois D'Ark, etc." I only hope that it might still be in print as, sadly, Dr. Tarpley passed away several years ago.
From personal experience I can tell you that it is called horse apple because horses love to eat the fruits. The things grow wild here in N. E. Texas and there is an area near here that used to be it's original 'natural range' I believe. The wood also delivers a LOT of heat when burned. When I had a wood stove and it was cold I would use regular wood during the day and add a horse apple log about 6 to 8 inches in diameter and at least a foot long to the stove near bed time. It would take a while to catch but once it did it was not advisable to open the stoves door because of the sparks it would shoot out. However, it would burn slow and hot enough all night to keep the house warm and often still be burning the next day! (Of course I am a Texan so you can take all that with a grain of salt if you wish!) I also know from painful experience that these trees have thorns but usually only on the younger branches.
I would be willing to send you some of the fruits as I have no clue how to separate the seeds out but it is spring now and all those that fell last fall have been eaten by horses, squirrels and other critters.
