He chases the season of rebirth around the world, in a 13-week adventure that is part global exploration, part horticultural quest. However, there is always an amazing glimpse of nature at its diverse and glorious finest. From the amazing fields of daisies in South Africa to the brilliant red poppies peeking through the ruins of Greece.
