I love the use of art,from a little statue off by its self or the fountain in the centerpiece.This is all soothing to someone and it gives each person there own time when viewing all to themselves.Plants are art in itself.All you Landscape architects are creating art each design you do.When I design an outdoor space and put my pergola product up ,i try to create the same soothing space.so a meaning would be .”A visual enhancement within a space of nature”.
