Who is she? Martha Schwartz is a New York-based landscape architect with as much pizzazz as the Hitchhiker's Guide to the Galaxy planet designer Slartibartfast. Does she have formal training? Yes, she is a Harvard design graduate. Define her style. Wild and wacky with lashings of colour - she believes society has a hang-up about designs that embrace the spectrum. Another Schwartz hallmark is humour with a twist of surrealism. How does she express it? Consider her first solo design project, the Bagel Garden. In 1979, Schwartz dipped real bagels in yacht varnish before placing them on purple gravel around the front yard of her Boston townhouse. Another outrageous Schwartz design - for the Rio Shopping Centre in Atlanta, Georgia - incorporates an army of 350 gilded frogs apparently worshipping a red geodesic dome. What's her story? Born in 1950, she has more than 25 years' experience as a landscape architect and artist. Despite her madcap approach, she has won many accolades, including a fellowship from the Urban Design Institute, several design awards from the American Society of Landscape Architects and a recent honorary fellowship from the Royal Institute of British Architects. She is also an adjunct professor of landscape architecture at the Harvard University Graduate School of Design. Does the corporate world have time for her quirky style? Yes, she designed five atriums for the new Barclay's Bank (right) at Canary Wharf, London. The official description says each space 'creates a new and unique address and image for its six-storey surroundings and gives people choices for how and where they want to exist within their office building'. What else has she conjured up? '51 Garden Ornaments' in Westphalia, Germany (2001), which is pitched as a reflection of our need for an escape from the information society and features a flower-patterned chair perched on a pedestal. Other highlights include the Wadsworth Atheneum Museum of Art, in Hartford, Connecticut (1999), the Mechtenberg Land Art Gallery, Germany (1997) and many more. Much of her work is temporary. However, London's Daily Telegraph quotes her as saying: 'If you can transform a space for the public for one second, that's better than not at all.'
