Habitus

Bryophyllum delagoensis, commonly called mother of millions, devil's backbone is a succulent plant native to Madagascar . Like other members of its genus Bryophyllum, it is able to propagate vegetatively from plantlets that develop on its phylloclade margins.[2].[2] Chandelier plant is an alternative common name.[citation needed]

This species' capability for vegetative reproduction, its drought tolerance, and its popularity as a garden plant, relate to this species' becoming an invasive weed in places such as eastern Australia and many Pacific islands. In the Neotropics hummingbirds sometimes pollinate this non-native plant.[3]

Bryophyllum delagoensis is unwelcome because it displaces native plants and contains bufadienolide cardiac glycosides[4] which can cause fatal poisoning, particularly in grazing animals like cattle.[5] During 1997, 125 head of cattle died after eating this species on a travelling stock reserve near Moree, NSW.[6]

Because of the toxicity of this species and its hybrids, and especially of the flowers, it has been declared a noxious weed in New South Wales and Queensland.
