The royal decrees and writings on landscape planning and trees planting of King Rama V represent his vision of Bangkok’s modern urban landscape. The objectives of planting were mainly for beautification, creating shaded area and natural environment of the city. There were varieties of both native and exotic plants, flowering and fruit trees.
