It was reported recently that a growing number of people in the United States were being sent package of the unidentified seeds and Doyle Crenshawn has begun using them on his plants.

He claims that they have had a spectacular effect on their growth.

Doyle told 5 News: ''Every two weeks I'd come by and put Miracle-Gro on it, and they just started growing like crazy.

''The package said it was from China and said 'studded earrings' on the outside, and we thought that was a little odd.''

Officials in the US had previously warned people not to plant the seeds as they are concerned they could pose an environmental risk.
