According to the David Austin Site:

‘Falstaff’ bears large, shallowly cupped blooms of rich, dark crimson, which eventually turn a wonderful shade of rich purple. They are of exquisite form and quality, packed with numerous petals which interfold at the centre. This helps to create a lovely, glowing effect within an enclosed saucer of outer petals. There is a powerful Old Rose fragrance.

Named for the well-loved Shakespearean character, who was the faithful companion of Prince Hal (the future Henry V).
