Kalanchoe blossfeldiana

Kalanchoe blossfeldiana is a herbaceous[2] and commonly cultivated house plant[3] of the genus Kalanchoe native to Madagascar. It is known by the English common names Flaming Katy, Christmas Kalanchoe, Florist Kalanchoe[4] and Madagascar widow's-thrill.[5]

Taxonomy and naming[edit]

Kalanchoe blossfeldiana is in the Kalanchoe section of the Kalanchoe genus, with a description of the plant published in 1934 (Repert. Spec. Nov. Regni Veg. 35:159).[6] With regards to the etymology of the binomial, the generic name Kalanchoe has been alleged to have originated "from the Chinese name for one of the species." [7] The Oxford English Dictionary states that it is "based on [the] Chinese gāláncài",[8] whilst the Collins English Dictionary merely restates the claim that the generic name was derived from the local Chinese name for one of the species.[9] The specific epithet blossfeldiana is in tribute to German hybridiser and botanist Robert Blossfeld, who first introduced the plant to the rest of the world in 1932.[10] The common name Christmas Kalanchoe comes from the plant's flamboyant and colourful blooms in winter.[11][12]

Description[edit]

Kalanchoe blossfeldiana is a glabrous,[11] bushy, evergreen and perennial succulent plant which (in 2–5 years)[13] can reach an ultimate height of between 30–45 cm (12-18 in.)[4] and an ultimate spread of between 10–50 cm (4-20 in.).[13] K. blossfeldiana has a round habit and a moderate plant density; its growth rate has been described as 'slow'.[2] The plant has green,[13] shiny and textured glossy foliage[4] which stays green all year round.[13] The scallop-edged and ovate leaves leaves are arranged in an opposite/subopposite fashion, are simple in type with crenate margins and an oblong shape.[2] 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.[2] 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.[4] The infloresences are born by peduncles which are higher up than the leaves and are terminal in nature.[14]

Parts of Kalanchoe blossfeldiana are poisonous if ingested.[4]

Distribution and habitat[edit]

Kalanchoe blossfeldiana is native to Madagascar, where the plant can be found growing in the relatively cool plateaus of the Tsarantanana Mountains; K. blossfeldiana in this environment grows in humus soil.[15]

Ecology[edit]

Whilst generally disease free, Kalanchoe blossfeldiana can be damaged by pest insects such as Otiorhynchus sulcatus (vine weevil) or mealybugs.[13]
