Also causing a stir at this year's event was Welsh exhibition vegetable grower Medwyn Williams who secured his 11th gold medal as well as the coveted President's Award for the second time.
Meanwhile, the University of Reading ensured the importance of science to horticulture was highlighted with an exhibit outlining its work with the National Fruit Collection at Brogdale.
The NFU display was created by award-winning florist Penny Ri-ley, who led the Chelsea team. The idea behind the exhibit was to highlight the diversity and exceptional quality of produce grown in Britain to the tens of thousands of visitors to the show.
Williams returned to the show after an absence of five years. Leeks propagated from pips removed from the seed head took centre stage on his stand.
On show at the University of Reading's stand were examples of its work at Brogdale, where it is responsible for scientifically curating and maintaining the collection.
