Bryophyllum fedtschenkoi, native to Madagascar, is widely sold as a house or garden plant. Its specific epithet fedtschenkoi honors botanist Boris Fedtschenko. It is a low-growing, untidy, erect to spreading ramified, perennial succulent herb.
Kalanchoe fedtschenkoi (Bryophyllum fedtschenkoi) also called 'South American Air Plant' or 'Lavender Scallops' is cultivated in the tropics and as a house plant in the temperate regions. The leaves are coloured metallic green and may turn pink or red under strong sunlight or drought conditions. The purple or reddish brown flowers are bell shaped and hang in loose clusters from upright stems in the winter. It grows in open ground at about 1.000 metres of altitude in semi-desert areas. It is widely sold as a house or garden plant that has established itself in the wild in some southern parts of the United States of America and perhaps South America too.
