This is the spot where Wordsworth 's sister Dorothy was stopped in her tracks by what she believed were the most beautiful daffodils she had ever seen ; her astonishment inspired Wordsworth to write about this host of golden Daffodils in one of the best-loved poems of the English language , I Wandered Lonely as a Cloud ( 1804 ) .
Dorothy collected some of the daffodils and brought them home for Wordsworth to see .
