The rose cultivar was developed by Harkness Roses (R. Harkness & Co. Ltd) at Hitchin, Hertfordshire. The acclaimed nursery, which continues to sell roses today, was established in 1879 in Bedale, Yorkshire by brothers, John Harkness (1857-1933) and (Robert Harkness (1851-1920). Jack Harkness (1918-1994) is the grandson of the original co-founder John Harkness. The Harkness family nursery grew roses from the beginning, but did not breed roses until 1962, when Jack Harkness began managing the business.
