Sheringham Park and rhododendrons are often referred to in the same sentence. Not surprising with 80 different species on show. Flowers first appear in December, and the show gradually builds to a climax from mid-May into June. Many plants were brought to Sheringham by plant collector Ernest Wilson in the early 20th century. The handkerchief tree, which grows at the edge of the wild garden, was found by Wilson in China. He discovered it working from a crude map on a scruffy piece of paper covering an area of 20,000 square miles with just an 'X' marking its location.
