The best time to look for mystery seeds is in the fall,
or the spring, or the summer. Occasionally in the
winter. Look anywhere for a tree you don't recognize -
this is a mystery tree. This particular tree is readily
visible in the early fall, when the leaves just begin to
fall. You will see the yellow fruits and wonder why an
orange or lemon tree is growing up here in the north.
Also, when you go to grab one of the fruits, the
thorns will rip all the flesh from your hand.
