Scientific name: Pelargonium sp.
Description: Indoor geraniums are bushy shrubs with soft-wooded, much-branching, brittle stems. The most common leaf shape is circular with slightly lobed edges. Individual flower size varies, but all have one or more layers of five spoon-shaped petals. Petal color can be white or shades of pink or red.
Light: Require at least four hours a day of direct sunlight to flower well.
Temperature: Normal room temperatures. A winter rest at about 50 degrees F
Methods of propagation: Use 3- to 4-inch long tip cuttings taken in summer.
Comment: Low humidity helps prevent “black stem rot”. Pinching the growing tips of young plants encourages a bushier growth habit.
