Answer 2

The White Rose of York is the symbol of the House of York and latterly of Yorkshire. The origins of the emblem are somewhat obscure, but it is said to have first been adopted by Edmund of Langley, the first Duke of York, in the 14th century. It represents the Virgin Mary, who was often called the "Mystical Rose of Heaven" (white being a symbol of purity).

The Red Rose of Lancaster is the symbol of the House of Lancester and county flower of Lancashire. The rose was first adopted as an heraldic device by the first Earl of Lancaster and became the emblem of Lancashire following the Battle of Bosworth Field in 1485. The rose does not form any part of the insignia of the Duchy of Lancaster, but came to be seen as an emblem of the county of Lancashire, and as such was incorporated in the coats of arms of numerous Lancashire local authorities including the county council.
