For more than a century, Vincent Van Gogh's series of paintings depicting overly-bushy sunflowers were thought to be the result of his alleged mental illness at work, but now could actually be realistic impressions of a genetic mutation seen in some strains of the flowers, according to a new study.

Development and morphology of insect-mimicking spots on the flower petals of a South African beetle daisy Dark spots on flower petals are common across many angiosperm plant families and occur on flowers such as some lilies, orchids, and daisies.
