Cyclamen persicum, also known as florist's cyclamen, is a perennial flowering plant prized for its heart-shaped foliage and flowers. A cool-season plant, cyclamen begins growing in the fall and blooms through the spring. Boasting attractive blooms in shades of red, pink or white, container-grown cyclamens often are given as gifts for Christmas or Valentine's Day. Caring for your indoor cyclamen is simple; getting it to rebloom the following season, however, requires a bit more effort.
Find a suitable location for the cyclamen in a temperature-controlled room of your home that is kept below 21.1 degrees C during the day and around 10 degrees C at night. Place the cyclamen within four to six feet of a sunny window that can provide it with at least six hours of bright, indirect sunlight per day. Avoid positioning your cyclamen within six feet of heaters or air vents, which can cause the plant to drop its leaves prematurely.
Water your cyclamen regularly to keep its growing medium moist, but well-drained. Pour water on the soil at the edge of the container to reduce the risk of tuber rot. Water the plant until water begins running out of the drainage holes in the bottom of the pot. Allow the top 1/2 inch of growing medium to dry before watering the cyclamen again.
Fertilise your cyclamen every three weeks from late fall to early spring with a half-strength mix of water-soluble houseplant fertiliser. Follow the instructions on the fertiliser package to avoid giving your plant too much fertiliser, which can result in more foliage, but fewer blooms.
Pull dead blossoms and leaves from your cyclamen as needed to maintain an attractive and healthy-looking plant. Removing spent flowers and foliage encourages the cyclamen to produce additional blooms.
Move the cyclamen to a cool, shady location when its foliage turns yellow and begins dropping from the plant. Continue watering the plant periodically during this dormant period to prevent the growing medium from drying out completely. Move the cyclamen back to its usual position and resume regular care in mid-September, or when it begins producing new leaves.
Cyclamen can be grown successfully outdoors in U.S Department of Agriculture plant hardiness zones 9 and 10.
