Kalanchoe blossfeldiana, also known as Flaming Katy, Christmas kalanchoe, florist kalanchoe, and Madagascar widow’s-thrill, is a commonly cultivated evergreen house plant of the genus Kalanchoe native to Madagascar. It is a glabrous, bushy, evergreen and perennial succulent plant which (in 2–5 years) can reach an ultimate height of between 30 and 45 cm (12 and 18 in) and an ultimate spread of between 10 and 50 cm (4 and 19.5 in). The plant has green, shiny and textured glossy foliage which stays green all year round. The scallop-edged and ovate leaves are arranged in an opposite/subopposite fashion, are simple in type with crenate margins and an oblong shape. The arrangement of the veins in a leaf (venation) can be absent or very hard to see; the leaf blades are 5–10 cm (2–4 in) long. K. blossfeldiana flowers in late autumn to early winter; each flower has four petals and can be one of a wide variety of colours, from the dark reds and pinks to oranges, golds and whites. K. blossfeldiana is a short-day plant, meaning that its blooming cycle is regulated by the amount of sunlight it receives each day. The plant will bloom when it is receiving approximately 10 hours of daylight and 14 hours of darkness for 6-8 weeks.
