What causes flowers to change colors?
In the past I have noticed that flowers will change colors especially in colder temperatures. Knockout roses will be darker in cold temperatures and certain camellia flowers will also darken in colder weather. This is due to the fact that certain colors’ chemical composition responds to temperature.
But what causes the flowers of identical plants to be different colors? I have two hibiscus plants that are blooming in a dark and a light color. I have had these plants for years, and in fact, one of these is from a cutting of the other, and this year they are sporting different colors.
Now, the lighter color is how this hibiscus has bloomed for years. It is more of a peach color. The darker flower is definitely orange. Both of these plants are in containers, next to one another, and have been fertilized, watered, etc. the same. So, why are the flowers a different color? And why now after so many years? I could understand if both were blooming the same darker color, but not one light and one dark. And with the heat we have been experiencing, it can’t be a result of one being in a cooler temperature.
One of the mysteries of nature, I guess.
Update on the St. Swithen’s Day rain forecast: If you read my previous entry, I just wanted to keep you posted on the rain. Yes, it has rained every day since that posting. I am almost ready to believe that forty day forecast of rain.
