This week's featured seeds come in some very tough packaging.
Outside is a pod enclosing several seeds. Within the pod are the seeds sealed into another layer of wrapping, which is extremely difficult to remove. In fact, this one was from a parking lot where it had been run over by cars, and the seed is still in its package.
Do you recognize what plant these seed pods are from? If you choose to, please leave a comment with your ideas.
Edit: The answer is now posted.
