What to do

GI upset is most common, but cardiac monitoring is warranted for larger ingestions given the toxin family.

Toxic component and mechanism

The toxic component in Devil's Backbone is bufadienolide cardiac glycosides (less potent than oleander).

What makes this plant different

One of several Kalanchoe species sold under dramatically different common names (Devil's Backbone, Mother of Millions, Chandelier Plant) despite sharing identical cardiac glycoside chemistry — the plant's habit of producing tiny plantlets along its leaf edges (giving it the 'Mother of Millions' name) makes it prone to spreading well beyond its original pot.
