In this part of Texas we have a tree called the Bois d'Arc. Being Texans, we call it the "bowdark." Ken tells me that the wood was used for bows and arrows by the native Americans, but I don't know if that's true.
Ken is very fond of their gnarly look.
It's generally the size of a softball or larger. Guess who eats them?
Squirrels. They like to carry them up into a tree and rip them apart (somehow!) and then throw down the little parts they don't want onto the driveway, or onto YOU. (There's a theory that the squirrels get high on them, but I have no idea about that, either.) But! The little pieces are terribly sticky! So are bowdarks if they get mashed by a car wheel. And then they decay....ewww. So right now I'm on bowdark patrol!
Bowdarks are also most fun to bowl. If you have a quiet street you can bowl them down the gutter. We don't, but we like to bowl them ACROSS our street and see how high they bounce when they reach the opposite curb. Be sure you don't have any stealthy bicyclists whizzing toward you; Ken pegged a guy one time. He felt terrible!
