Plants grow up to tall and have
opposite-decussate, fleshy ovate to elongated-triangular leaves which grow up to long and wide. They are green above and blotched with purple underneath. Leaf margins have spoon-shaped
bulbiliferous spurs which bear plantlets which may form roots while still attached to leaves. A plant may also develop
lateral roots on its main stalk, as high up as above the ground. A plant's upper leaves may grow large, causing its main stalk to bend downward. Then the lateral roots may enter soil and new vertical shoots may grow from the original shoot.
Kalanchoe daigremontiana can spread by both seeds and by plantlets dropped from its leaves.
Kalanchoe daigremontiana has an umbrella-like terminal
inflorescence (a compound
cyme) of small bell-shaped, grayish pink (or sometimes orange) flowers. Flowering is, however, not an annual event and occurs sporadically if at all on some shoots. Particularly in climates with distinct seasonal temperature differences, flowering is most frequently observed at the beginning of a warm season. Indoor plants, as well as balcony plants which have been moved inside to survive the cold season, begin flowering in early winter. As a succulent plant,
Kalanchoe daigremontiana can survive prolonged periods of
drought with little or no water. During growth periods with higher temperatures and increased water supply, this species requires proper nutrition, without which leaves show deficiency symptoms such as crippled growth and pustule-like lesions. The plant is not frost-hardy and typically dies in places where temperatures are below freezing. == Physiology ==
