    Thank you so very much. I found this “thorn apple “ growing in my yard under a walnut tree. It was unusual so I asked a friend by sending a photo. She referred me to your institution.

  2. Patricia Slade says:

    I found this plant in the middle of my garden and had no idea what it was or how it ended up in a garden that hasn’t been added to in years. It looks healthy and stands about 2.5 feet tall. I was happy to see it will eventually flower.

  3. Marge Dembowski says:

    I found this plant in my garden and it’s extremely large. The stems are almost tree like. After reading about this plant I’m concerned for the safety of me and my pets. Please tell me how to get rid of this plant or will it die on its own and not return

    1. Eric Biggane says:

      It can not cause poisoning unless ingested so I would leave it alone. If it must be removed it should be cut back to ground level and the stump removed.

  4. Lynne barner says:

    Can it be brought in by birds

    1. Eric Biggane says:

      Birds can be responsible for spreading this plant and the seeds can stay viable for years until the perfect conditions.
