Kalanchoe daigremontiana

Formerly known as, Bryophyllum Daigremontianum, the Kalanchoe Daigremontiana is commonly called mother of thousands, alligator plant, or Mexican hat plant is a succulent plant native to Madagascar. Like other members of the genus Bryophyllum, it can propagate vegetatively from plantlets that develop between the serrations on the foliage edges (phylloclade margins). All parts of this species contain a very toxic steroid known as daigremontianin, resulting in its name. 

The Mother of Thousands plant is especially fun to care for if you are looking to experiment with propagation, as this plant can produce hundreds of tiny plantlets at a time.  Like other members of the Kalanchoe family, it is best to only deeply water when completely dry.

3-6 hours of sun per day, with protection from intense mid-day sun

Water moderately, allowing the top 3cm to dry out between watering.
