Kalanchoe houghtonii

A hybrid of Kalanchoe daigremontiana and K. delagoensis, sometimes called mother of millions. It forms plantlets along its leaf edges and has become invasive across warm parts of the world. It is easy to grow in bright sun with sparse watering. All parts are toxic to pets and livestock, and the plantlets self-sow aggressively.

Where it grows wild

The single native record is in the dry south-west of Madagascar, an area of spiny thicket and scrub on sandy or rocky ground. Where it has been introduced, it colonises disturbed, sunny, well-drained sites.

The one Madagascar record is at about 120 m near the south-west coast.
