Kalanchoe delagoensis

Kalanchoe delagoensis, formerly known as Bryophyllum delagoense[2] and commonly called mother of millions or Chandelier plant,[3] is a succulent plant native to Madagascar. Like other members of Bryophyllum (now included in Kalanchoe[1]), it is able to propagate vegetatively from plantlets that develop on its leaf margins.

Habitus

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.[4]

Kalanchoe delagoensis is unwelcome because it displaces native plants and contains bufadienolide cardiac glycosides[5] which can cause fatal poisoning, particularly in grazing animals like cattle.[6] During 1997, 125 head of cattle died after eating this species on a travelling stock reserve near Moree, NSW.[7]

In the Australian states of New South Wales[8] and Queensland,[9] this species and its hybrids have been declared a noxious weed.
