About Kalanchoe blossfeldiana Poelln.
Kalanchoe blossfeldiana is a glabrous, bushy, evergreen, perennial succulent plant. Over 2–5 years, it reaches a final height of 30 to 45 cm (12 to 18 in) and a final spread of 10 to 50 cm (4 to 19.5 in). This species has a rounded growth habit, moderate plant density, and a documented slow growth rate. It produces green, shiny, glossy textured foliage that remains green year-round. Its leaves are ovate with scalloped edges, arranged in an opposite or subopposite pattern, and are simple with crenate margins and an oblong shape. Leaf venation is either absent or very difficult to see, and leaf blades measure 5–10 cm (2–4 in) in length. Parts of Kalanchoe blossfeldiana are poisonous when ingested. Kalanchoe blossfeldiana is native to Madagascar, where it grows on the relatively cool plateaus of the Tsarantanana Mountains in humus soil. Although it is generally disease-free, Kalanchoe blossfeldiana can be damaged by pest insects including vine weevils (Otiorhynchus sulcatus) and mealybugs. For cultivation, Kalanchoe blossfeldiana has a minimum tolerated temperature of 10 °C (50 °F). In temperate regions, it requires protection under glass during the winter months, and needs a cool, partially shaded growing location. It may be moved outdoors for the summer. In the United Kingdom, this plant has been awarded the Royal Horticultural Society's Award of Garden Merit.
