I bought this land in 1983 and the previous owner had driven an old red pick-up truck from California . Some place along the way they must have parked under a mulberry tree and some of the berries must have fallen in the bed of the truck. I gave the truck to a neighbor and he towed it away with his tractor and where it was parked, the tree grew. My book tells me it could be a moutain, Texas or Mexican mulberry and sometimes it grows in a clump. What do you think ?
