Kalanchoe laxiflora

Kalanchoe laxiflora, the milky widow's thrill, is a species of perennial flowering plant in the family Crassulaceae. A succulent subshrub reaching 50 cm (20 in), it is typically found growing on rocks in deserts and dry shrublands. It is native to east-central Madagascar, growing primarily in dry shrublands. As an ornamental plant, it has been introduced to many locales around the world, including Italy, Sicily, Morocco, Algeria, Zimbabwe, Mauritius, Réunion, Hawaii, the Leeward Islands, the northern Andes, and Brazil. It is becoming widely invasive as a garden escapee.
