caption_attribution_description: Kalanchoe tomentosa, or Panda Plant, is a native of Madagascar. It is a beautiful succulent plant with dense white felt-like hairs covering the entire leaf. Leaf tips have shallow notches that are marked brown. With great age they will reach about 18 inches (45 cm) in containers and as far as I know they are not poisonous to animals or humans. They are hardy in USDA zones 9-12.
context_page_description: The Crassulaceae, also known as the stonecrop family or the orpine family, are a diverse family of dicotyledon flowering plants characterized by succulent leaves and a unique form of photosynthesis, known as Crassulacean acid metabolism. Flowers generally have five floral parts. Crassulaceae are usually herbaceous but there are some subshrubs, and relatively few treelike or aquatic plants. Crassulaceae are a medium size monophyletic family in the core eudicots, among the order Saxifragales, whose diversity has made infrafamilial classification very difficult. The family includes approximately 1,400 species and 34–35 genera, depending on the circumscription of the genus Sedum, and distributed over three subfamilies. Members of the Crassulaceae are found worldwide, but mostly in the Northern Hemisphere and southern Africa, typically in dry and/or cold areas where water may be scarce. although a few are aquatic.
  Crassulaceae are mainly perennial and have economic importance as garden plants. Many members have a bizarre, intriguing appearance, and are quite hardy, typically needing only minimal care.
context_section_description: Crassuloideae is the smallest subfamily, representing a single monophyletic clade (Crassula), defined by haplostemonous androecia (characterized by a single whorl of stamens, the number of which equals the number of sepals, petals and carpels, and alternating with the petals). Although cosmopolitan in distribution, the center of diversity is southern Africa, with only the aquatic species being found more widely. It consists of two genera and about 250–300 species (Berger's other four genera (Dinacria, Pagella, Rochea, Vauanthes) having been subsumed into a larger Crassula s.l.). Crassula is morphologically diverse and up to 20 sections based on phenotypic features have been described. One of these, Tillaea, has at times been considered a separate genus. Hypagophytum is a monotypic genus:
  Crassula L. (including Tillaea L.) c. 200 spp.
  Hypagophytum A.Berger 1 sp.
