Geraniums are attractive, easy-to-grow flowers. They come in many different colors and are popular both in the garden and as houseplants. In the garden they will spread to cover large areas, if allowed.
Many different kind of geraniums are cultivated for specific characteristics. Each one has qualities — leaves, color or hardiness — that set it apart from the others, such as the ivy geranium, hardy geranium and zonal geranium.
All varieties of geraniums can be rooted in water. A cutting 3 or 4 inches long is dipped in rooting hormone, then placed in a small pot filled with water and perlite or another porous medium. Roots will appear after about six or eight weeks.
Rooted cuttings can be transplanted into well-drained soil once the roots are over an inch long. The plant needs sunlight and water at this point. Once it starts, it will grow into a copy of the original plant.
