Peter Beales Roses company director Amanda Beales has died aged 45 after a long illness.
She had worked with her brother Richard, her father Peter, who died earlier this year, and her mother Joan, who died late last year, at the firm in Attleborough, Norfolk.
She had been responsible for breeding and introducing a number of well-known roses including Clarence House, St Ethelburga and Macmillan Nurse, the forerunners of the Modern Classic Rose range.
She also wrote a number of books including "Roses a Colour Guide, as well as painting roses.
Managing director and Amanda’s brother, Richard Beales, said: "This is another terrible loss to the company and to me personally, but I know that I must ensure that the legacy that my family created lives on through what was the passion for all my family - classic roses."
Amanda studied at Burlingham College of Horticulture and completed apprenticeships at Howard Nurseries and then at Peter Beales Roses.
She leaves behind a daughter, Laura, son, Alex, and partner Wes.
Her funeral will be held on August 22 at 2.30pm at St Mary’s Church in Attleborough.
