Xa Tollemache learned how to garden, and how to design gardens, at her home, Helmingham Hall in Suffolk. She set up her garden design practice in 1996, and one of the very first gardens she designed as a professional was the Evening Standard garden for the 1997 Chelsea Flower Show - for which she won a Gold Medal. She has since designed two more medal-winning gardens for Chelsea, as well as gardens all over the UK and in Europe and the US. She is currently a Member of the Council of the RHS, Chair of the Gardens Committee, a Member of the Horticulture Board and an RHS Judge.
