Habitus

Bryophyllum delagoense is a succulent plant native to Madagascar. In common with some other members of its genus, B. delagoense is notable for vegetatively growing small plantlets on the distal ends of its phylloclades, leading to its common names of mother of thousands, 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]

Byrophyllum delagoense is unwelcome because it displaces native plants and contains bufadienolide cardiac glycosides^[4] which can cause cardiac poisoning, particularly in grazing animals.^[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.
