About

Kalanchoe pinnata, commonly known as cathedral bells, air plant, life plant, miracle leaf, and love bush, is a succulent plant native to Madagascar. It is a popular houseplant and has become naturalized in tropical and subtropical areas. The species is distinctive for the profusion of miniature plantlets that form on the margins of its leaves, a trait it has in common with some other members of Bryophyllum (now included in Kalanchoe).

How to grow it

In temperate regions, Kalanchoe pinnata is grown as an indoor ornamental plant. Like most succulents, it cannot survive hard frost and will not thrive in environments in which the temperature drops below 10 °C (50 °F). It favours well-drained soil, the roots being otherwise susceptible to rot. In the tropics, K. pinnata is grown outdoors in gardens, from which it may escape to become naturalised - often as an invasive weed.

Safety

In common with other species belonging to the Crassulaceae (including certain members of the genera Tylecodon, Cotyledon and Adromischus), Kalanchoe pinnata has been found to contain bufadienolide cardiac glycosides These can cause cardiac poisoning, particularly in grazing animals.

Bryophyllum pinnatum has been recorded in Trinidad and Tobago as being used as a traditional treatment for hypertension.

Where it grows

Kalanchoe pinnata is native to Madagascar. and has become naturalized in tropical and subtropical areas, inhabiting warm and temperate climates from sea level to 2,600 m (8,500 ft), occupying sites on rock in tropical evergreen and dry deciduous forests, as well as montane forests. It is found in parts of Asia, Africa, Australia, New Zealand, the West Indies, Bermuda, Macaronesia, the Mascarenes, Brazil, Suriname, the Galapagos Islands, Melanesia, Polynesia, and Hawaii.
