Clivias are flowering plants that are grown indoors as houseplants in most climates. Clivia flowers bloom in winter, producing dense clusters of lily-like, vibrant orange flowers. Clivia plants also have attractive, dark green leaves that make the plant lovely even when it isn't blooming. Some clivia varieties bear flowers atop 20-inch-tall stems, while other types have flowers that grow closer to the base of the plant. Clivias can grow 2 to 3 feet tall and wide and tend to be heavy, requiring a sturdy, heavier pot to keep the plant from tipping over.
Place your clivia flower in bright, indirect light, such as a sunny window with northern, eastern or western exposure. Keep the clivia away from hot, direct sunlight.
Water your clivia two or three times per week during spring and summer to keep it evenly moistened at all times. Provide water until the water drains from the bottom of the pot and be sure to allow the topmost layer of soil to dry out slightly before watering.
Feed your clivia once each month during spring and summer with a liquid 20-20-20 NPK fertilizer. Apply the fertilizer at half the normal dosage rate.
Divide and re-pot your clivia plants any time of year by pulling or cutting the plant apart into clumps that each have plenty of roots and leaves. Pot the divided clumps into organic, well-draining potting soil.
Stop fertilizing and reduce the watering frequency of your clivia flower in the fall to provide a six- to eight-week rest period. Place the clivia in a cool room with nighttime temperatures of 50 degrees Fahrenheit and water the plant when the foliage begins to wilt.
