Like other members of Bryophyllum (now included in Kalanchoe[2]), it is able to propagate vegetatively from plantlets that develop on its leaf margins.

It is a robust, completely bare, biennial or more or less perennial, succulent plant that reaches heights of between 0.2 and 2 meters.

[5] Kalanchoe delagoensis is unwelcome because it displaces native plants and contains bufadienolide cardiac glycosides[6] which can cause fatal poisoning, particularly in grazing animals like cattle.

[7] During 1997, 125 head of cattle died after eating this species on a travelling stock reserve near Moree, NSW.

[8] In the Australian states of New South Wales[9] and Queensland,[10] this species and its hybrids have been declared a noxious weed.
