San Francisco residents have a particularly strong liking for topiary trees, as apparent from these photographs taken by three different photographers. One is Marc Alcock, a British photographer, who after moving to San Francisco in 2010, became interested in photographing the visual differences between the two places. One of the things that struck him about San Francisco, Los Angeles and the surrounding suburbs were the houses and the unique relationship they have with plants and nature.
