The Sybil Sassoon gardens at Houghton were opened to the public in 1996. Lady Sybil's grandson, the current marquess, developed the gardens in honour of his grandmother. In 2008, the garden was named Historic Houses Association and Christie's Garden of the Year.[1] In "the pool garden", the entwined initials "SS" are represented in the outlines of the clipped box-hedge which surrounds plantings of lavender and rosemary.[2] Sassoon died in Cheshire. Through her son George Hugh Cholmondeley, Sybil is the great-grandmother of actor Jack Huston.[citation needed]
