The Passion Flower (Passiflora) is so called because it symbolised Christ’s suffering on the cross – that was according to Jacomo Bosio, a scholar who lived in Rome in 1609. The unique corona represented the crown of thorns, the ten sepals and petals represented the Apostles and so on.

The Passion Flower is a very good visual example of how Fibonacci numbers seem to govern so much of the world around us.
