Geraniums come in a variety of brilliant colors. In fact, the geranium can be considered one of the most colorful of garden plants, as both the flower and the leaf color can vary from plant to plant. The color of the geranium plant is genetically determined and can't be altered, so you'll need to choose your plants carefully if you have a specific color combination in mind. This article will outline the options available and discuss why the plants even have colorful flowers to begin with.
Geranium flowers come in white, pink, red, fuchsia, salmon and light purple. Some plants produce flowers that are striped with white and some plants produce flowers that have several colors in each petal. Leaf colors very from green to red, orange or yellow. Some leaves are striped and others are solid colors. Geranium flower and leaf colors are genetically determined and can't be changed through soil pH. If you pull a leaf from a geranium and start a new plant, that new plant will have the same leaf and petal color as the parent plant. Geraniums produce flowers from the spring clear until the fall. Flowers are produced in ball-like clusters on 3-inch stalks, meaning that their color is easy to see from quite a long distance away.
So, why do plants produce these colorful flowers and leaves? The answer is simple: Color attracts bees and birds. These small creatures use the color of the flowers as a sort of test, to make sure the pollen inside the flower is fresh and ready for sipping. They sip the nectar, and pick up a little pollen in the process. The pollen is then spread to other flowers. Birds and insects may not see colors in the same way we do, but it is clear that they are attracted to the bright, vibrant geranium colors.
