Patricia Hewitson, 65, of Exmouth, England, said she emailed a photo of the plant to BBC Devon's "The Potting Shed" radio show after being unable to identify the 5-foot-high plant, which she said had been giving off a strong odor. Advertisement Hewitson said she first spotted the plant in July and her husband, who studied botany in college, told her not to worry about it. Host Sarah Chesters told the grandmother police were being notified of the "illegal plant," but the woman would not be facing charges since the plant was grown accidentally. Experts said the plant may have grown from a cannabis seed in a package of bird seed used by the pensioner to feed the avians in her yard. "I found it very funny," Hewitson said of the discovery. "Possibly a source of pensioner income," she joked.
