Bryophyllum daigremontianum, commonly called mother of thousands, alligator plant, or Mexican hat plant is a succulent plant native to Madagascar. Like other members of its genus Bryophyllum, it can propagate vegetatively from plantlets that develop on its phylloclade margins. All parts of this species contain a very toxic steroid known as daigremontianin. Plants grow up to 1 m (3 ft 3 in) tall and have opposite and whorled, fleshy oblong-lanceolate phylloclades which grow up to 20 cm (6-8 inches) long and 3.2 cm (1.25 inches) wide. They are green above and blotched with purple underneath. Phylloclade margins have spoon-shaped bulbiferous spurs that bear plantlets which may form roots while still attached to phylloclades. A plant may also develop lateral roots on its main stalk, as high up as 10–15 cm above the ground. A plant's upper phylloclades may grow large, causing its main stalk to bend downward. Then the lateral roots may enter the soil and new vertical shoots may grow from the original shoot. Kalanchoe daigremontiana can spread by both seeds and by plantlets dropped from its phylloclades.
