Kalanchoe /ˌkælənˈkoʊɪ/

Common name: Kalanchoe · Flaming Katy · Widow's-thrill

Kalanchoe is a genus of about 125 species of succulents, mostly native to Madagascar and tropical Africa. The most familiar species, Kalanchoe blossfeldiana, is sold as a flowering houseplant with clusters of long-lasting blooms. Like many succulents, they prefer bright light and infrequent watering.

Fun facts

  • It is a 'short-day' plant, blooming when nights are long.
  • Florist kalanchoe can be rebloomed with weeks of long, dark nights.
  • Some species grow tiny plantlets along the edges of their leaves.
  • The name comes from a Chinese word recorded by a French botanist in the 1700s.
