I had a really interesting conversation with Stephen Hendry, from Newington Nurseries, the other day. Stephen's growing the plants for the Cayman Islands exhibit in the Great Pavilion, which is going to be an out-of-the-water underwater garden. Stephen was describing some of the more unusual plants that they're using and which really have the appearance of being underwater. Which is interesting because rumour has it that at the other end of the pavilion another exhibitor is going underwater and bringing piranha's to the show...!
