Kalanchoe beauverdii

Kalanchoe beauverdii, or Beauverd's widow's-thrill, is a climbing succulent species of Kalanchoe subg. Bryophyllum native to Madagascar. The species used to include many different forms with great variations. Now the broad-sense K. beauverdii has been treated as a series, Kalanchoe ser. Vilana, which includes four species: K. beauverdii, K. costantinii, K. guignardii, and K. scandens. The narrow-sense K. beauverdii differs from the other species of the series in its petiolate leaves.
