Ted Hughes (English poet, 1930-1998) worked for the firm during the summer of 1955. "The job is following round the expert as he grafts expensive rose-buds onto common bushes, and doing all the trimming and tying-up-with-raffia - a back-breaking job apparently, but outside, and with roses, and with good employers." §
Jack Harkness (1918–1994) began developing new roses for the company in 1962, and improved roses' health by introducing genes from various wild rose species. Early successes were with Hybrid Teas, and then later with Floribundas.
