Meet Our Trustees

Scotland’s Gardens Scheme is overseen by a Board of Trustees who oversee the charity’s financial performance and strategic vision. The trustees each bring their own expertise to the table.


David Mitchell (Chairman)

After thirty years at the Royal Botanic Garden Edinburgh, mostly as a curator, David recently retired to become a Research Associate at the RBGE. He sees his role as Chairman as ambassadorial and outreach especially highlighting the work of our volunteers and garden openers, using a collegiate approach to the organisation’s governance wherever possible. He is also Director and Curator of Muddy Feet Consultants, his own environmental education company that specialises in landscape assessment, project development, horticulture, interpretation and exhibitions. In addition to his long career as broadcaster with the BBC, STV, Channel Four and Radio Scotland, David is also a respected lecturer and tour leader leading groups for travel companies and Ivy League Universities around the globe. He believes that gardens and access to them is vital for the well being of people of all ages and backgrounds as well as for the cultural good of the nation.  Trustee and Vice Chairman of the National Trust for Scotland, he also served as Trustee of the Pitlochry Festival Theatre for 16 years. He currently lives in Edinburgh with his wife Catherine, his best friend, life long supporter and guiding light, and the ‘skinny whippet’ the infamous ‘Mr. Lowry’. In his spare time he enjoys art, antique porcelain, adding to his extensive library, playing music and cooking.

Having visited many of the amazing gardens opened on behalf of the charity over the past 40 years, he was delighted to become Honorary Treasurer of Scotland’s Gardens Scheme (SGS) in 2011. Peter oversees the financial running of the charity as well as our OSCR reporting.
