According to the Daily Mail, U.K horticulturalist Chris Beardshaw has conducted an experiment into the listening habits of plants. His discovery; that plants dig metal. The study came about because one of Beardshaw's horticultural students was planning to write a dissertation based on the effects of music on plants:
"We set up four glasshouses with different sorts of music in to see what happened to the plants," said Beardshaw (via Blabbermouth).
"We had one that was silent - that was a control house - and we had one that was played classical music, we had one that was played Cliff Richard and we had one that was played Black Sabbath. It was alstroemerias we were growing and we bombarded these glasshouses with sound for the life of the plant."
"We were measuring incidence of pest and disease, we were measuring inter-nodal distance, we were measuring the floriferous nature of them and that sort of thing and so the one that was grown as a control house grew really well as you'd expect."
"The one that was grown with classical music - a soft, almost a caressing of the plant when it is hit with that sort of soundwave - those grew slightly shorter because of the soundwaves bombarding them and were slightly more floriferous and there was slightly less pest and disease."
"And the ones with Black Sabbath - great big, thumping noise, rowdy music - they were the shortest, but they had the best flowers and the best resistance to pest and disease."
"The alstroemerias in the Cliff Richard house all died. Sabotage was suspected, but we couldn't prove it."
