Bryophyllum daigremontianum requires minimal care and can tolerate dry conditions and high temperatures. It is an unusual, fast growing succulent.
It is a succulent perennial plant native to the Fiherenana River valley and Androhibolava mountains in southwest Madagascar.
It has been introduced to numerous tropical and subtropical regions, such as Florida, Puerto Rico, Hawaii, parts of the Canary Islands and Australia.
Like other members of the genus Bryophyllum, it is able to propagate vegetatively from plantlets (epiphyllous buds) that develop on the leaf edges.
The plantlets that grow on the edges of each leaf fall easily and root wherever they land.
It is commonly found growing on gravelly and sandy soils.
This succulent plant is a weed of bushland and disturbed sites such as roadsides, along fence lines, around rubbish tips and abandoned rural dwellings.
It also occurs frequently along creeks and rivers where it is spread by floodwaters.
Bryophyllum daigremontianum grows from a single unbranched stem 45-90cm (18-35 inch) tall, which carries opposite pairs of fleshy, shiny, lance-shaped leaves that are 10-25cm (4-10 inch) long.
The leaves grow at an 8° angle to the stem and are bluish green with purple blotched undersides.
The saw-toothed leaf edges curl slightly inward.
The plant dies after blooming. Flowering is, however, not an annual event and will occur sporadically if at all.
Particularly in climates with distinct seasonal temperature differences, flowering is most frequently observed at the beginning of a warm season.
Bryophyllum daigremontianum take a year or two to mature.
