The seed pod that looks like a porcupine belongs to the datura inoxia, it is a perennial with flowers that are very similar, but larger than the Moonvine annual that can be grown in the midwest.babygirl33374's rebuttal: Thank you for letting me know that. I'm pretty new to the gardening thing, but my neighbor gave me the seeds and she thought it was a moon flower. It does bloom at night to. Thanks again
