Hemerocallis 'Cynthia Mary' is a late flowering Daylily cultivar produced by Lady Carew-Pole, who held a National Collection of Hemerocallis at Anthony House in Cornwall. The flower is a deep cherry red with a large amber coloured throat. Like most other daylilies, Hemerocallis 'Cynthia Mary' produces many flowers, with the flowers being held on long stems well above the leaves, growing to around 60cm tall.
