Jeff Cox explores the factors that affect flower color, particularly true blueGARDENERS THROUGH THEages have sought the true blue rose—without success. Lavender was about as close as rose breeders got to blue, when they developed 'Angel Face' in 1969.Recently, Japanese bioengi-neers got the idea of inserting the gene in violas and delphiniums that produces delphinidin, the anthocyanidin responsible for the true blue color in those genera, into the DNA of an old garden rose named 'Cardinal de Richelieu'. The result was a rose that varied from mauve to lavender to pastel violet. They bravely named it 'Applause', and florists began selling it as a "nearly blue" rose at 10 times the price of ordinary roses.
