what are zonal geraniums
Description: Zonal geraniums are bushy plants, mainly used for containers and bedding. There has been considerable breeding done, particularly for size and abundance and colors of flowers, so there is a good deal of variety. 1  Leaves: Oval leaves grow on succulent stems.2  The leaves often have zones of maroon or bronzy-green.esign Suggestions: Zonal geraniums have gotten a bad reputation by plant snobs. They've been considered garish and common. Too many of the brightly colored plants can start to look over the top, but these plants are excellent in all kinds of containers.
