Art Meets Science: Color Changing Flowers

Purple and White Petunias

Flowers are currently being developed that change color either throughout the day or on demand – a meeting of art and science. Based on circadian rhythms, your pink petunias in the morning would change to purple flowers by afternoon. Or based on watering, your petunias would change from white to pink to purple within 24 hours. Petunias in the past have played a critical role in the study of RNAi and its potential impact on the treatment of human disease (which led to a Nobel prize in 2006).  Flowers have been cultivated and bred for centuries, and this is one more way to increase man’s pleasure from plants.  

About Pam
Richard and Pam lived in the San Francisco Bay Area 14 years (1987-1999 and 2008-2011). They lived in Florida 13 years previously, until returning in July 2011 to present. They hope their photography will encourage you to get out and discover nature's beauty in your own backyard, parks, and wild places.
