There are six known cultivated species of clivia, which is a flowering plant native to South Africa, according to the University of Illinois Extension office. In the United States and Europe they are often kept as houseplants and suffer from a common pest called mealybugs.
Clivia Growing Conditions
As houseplants, clivias prefer bright indirect light, and they require shade if moved outside in summer. They thrive in dry soils and will develop root rot if the soil is too wet. Clivias bloom more frequently when root-bound in a small pot.
Pests and Diseases
Clivias rarely suffer from diseases, but they may attract mealybugs, which should be treated or the health of the plant may suffer.
These creatures are also called scale insects and are common pests on house plants—including clivia—when conditions are warm and moist. They are also a problem in greenhouses and subtropical climates.
The mealybugs attach themselves to crevices, plant stems and roots of clivia and feed on the plant’s sap. This can inhibit the plant’s growth and may also result in wilting or loss of leaves.
Infestations of mealybugs can be eliminated by cleaning the affected areas with a cloth or cotton swap soaked in alcohol.
