Patricia Hewitson from Exmouth, Devon, unwittingly grew a 5ft (1,5m) tall cannabis plant from a pack of bird seeds.

She contacted BBC Radio Devon's gardening programme The Potting Shed for help identifying the plant. Gardening expert Sarah Chesters was able to identify it from a photo.

After discovering it was an illegal cannabis plant the police advised Mrs Hewitson and her husband to remove it.

Cannabis is illegal to grow without a licence, but police said no further action would be taken.
