how to care
Like other succulents, Calandiva needs well-draining soil with a slightly acidic or neutral pH level. Add sand or perlite to potting soil, or buy a mix made for succulents and cacti. Plant Calandiva outdoors, about 20 to 30 cm apart. Give the plant full sun outdoors and as much sunlight as possible indoors, either in direct sunlight or indirect, bright sunlight. A lean looking plant can result from low light.
As Calandiva is a drought tolerant plant, it is better to err on the side of too little water than too much. Water the plant well every week or so, but wait until the soil is dry before watering again. 
Apply a balanced fertilizer once a month during the growing season to encourage flowering, using a liquid fertilizer for an indoor plant and a liquid or granular type for an outdoor plant.
Little pruning and pinching is all Calandiva needs to encourage flowering and create a thicker, fuller shape. Cut the tall stems that rise above the leaves after the flowers have finished blooming. Leave small new plant shoots that form at the tips of the remaining leaves if you want your plant to grow.
 
Origin
The Calandiva series was discovered in 1998 by a Swedish grower who noticed a  purple mutant Kalanchoe blossfeldiana that had 32 petals instead of 4. The plant was intensively cultivated and then introduced to gardeners in 2002.
