kalanchoe
Cultivation and uses;
These plants are cultivated as ornamental houseplants and rock or succulent garden plants. This plant is known to the Chinese as "10,000 purple 1,000 red" and is commonly purchased during the Lunar Calendar New Year for decorative purposes.[citation needed] They are popular because of their ease of propagation, low water requirements, and wide variety of flower colors typically borne in clusters well above the phylloclades. The section Bryophyllum—formerly an independent genus—contains species such as the "air-plant" Kalanchoe pinnata. In these plants, new individuals develop vegetatively as plantlets, also known as bulbils or gemmae, at indentations in phylloclade margins. These young plants eventually drop off and take root. No males have been found of one species of this genus which does flower and produce seeds, and it is commonly called, the Mother of Thousands; the Kalanchoe daigremontiana is thus an example of asexual reproduction.These plants are the food plant of the caterpillars of Red Pierrot butterfly. The butterfly lays its eggs on phylloclades, and after hatching, caterpillars burrow into phylloclades and eat their inside cells
