Sunflowers (original title, in French: Tournesols) are the subject of 2 series of still life paintings by the Dutch painter Vincent van Gogh. ...the second set, executed a year later in Arles, shows bouquets of sunflowers in a vase. ...Neither the third nor the fourth shows the dozen or 14 flowers indicated by the artist, but more—15 or 16.
