Constance Spry (5 December 1886 - 3 January 1960) was a famous British educator, florist and author in the mid-20th century. In 1921, she was appointed headmistress of the Homerton and South Hackney Day Continuation School in east London, where she instructed teenage factory workers in cookery and dressmaking, and later flower arranging. In 1936, "Flower Decoration" created the flower arrangements for the royal weddings of the Duke of Gloucester to Lady Alice Christabel Montagu-Douglas-Scott and the more private wedding of the Duke and Duchess of Windsor in June 1937.
