This picture is from an Italian Garden (known for their perfection.)
This is part of the garden at Sissinghurst Castle, which was actually created in the 1930s but based off of classic English gardens.
Some of the oldest gardens are Roman gardens, this one has been restored, obviously, but this just goes to show you that even way back then people found beauty and art in the biological world. They have even uncovered marvelous gardens in Pompeii. These Roman gardens are essentially the basis for all other gardens.
