Habitus

Bryophyllum delagoensis is a succulent plant native to Madagascar. In common with some other members of its genus, B. delagoensis is notable for vegetatively growing small plantlets on the distal ends of its phylloclades, leading to its common names of mother of millions,[2] and devil's backbone.[2] Chandelier plant is an alternative common name.

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.
