Kalanchoe (Kalanchoe blossfeldiana) is a dark-green succulent that grows indoors or out, in containers or in the ground. It is often referred to as Christmas kalanchoe because it blooms in winter. This decorative plant boasts striking flowers. The species name, blossfeldiana, honours Robert Blossfeld, a hybridiser who introduced it in Europe from its native Madagascar. Calandiva is a brand name; it is a cultivar, or variety of kalanchoe bred from Kalanchoe blossfeldiana. Calandiva is highly ornamental.

Kalanchoe is known for its extremely showy flowers that bloom in pink, red, yellow, white and orange. The multibranched succulent is long-blooming from winter through spring. The leaves have scalloped edges; large clusters of flowers present themselves on short stems above the foliage. Kalanchoe is often used as a houseplant but makes a good cool season bedding plant or attractive container plant. Present-day kalanchoes do not need to have the spent flowers removed.
The highly ornamental 'Calandiva' series is known for its roselike double flowers in an ever-increasing colour palette. It was discovered in 1998 by a Swedish grower who noticed a purple kalanchoe mutant that had 32 petals instead of four. The plant was intensively bred and then introduced to gardeners in 2002. The colours include white, cream, yellow, salmon, light pink, rose, lavender, red and burgundy.
These plants thrive outside in United States Department of Agriculture hardiness zones 10 through 11, where they survive temperatures to -1.11 degrees Celsius. The perennial plant slowly grows up to 1 foot tall and as wide in either part shade or part sun. It tolerates slightly alkaline, sand or acidic soil and its drought tolerance is high. Lightly fertilise the succulent once a year. If the plant is outside, protect it from frost and watch for caterpillars and mealy bugs.
The succulent is easily propagated and one of the best ways is by stem or tip cuttings. After the flower is done, find a stem with two pairs of leaves that is about three inches long. Cut the stem and lay it out to dry in the house or outside if there is no danger of frost. After two days, simply stick the stem in the planting medium; no fertiliser is required. A recommended rooting medium consists of one part peat to one part sand.
