Highly toxic to non-toxic - brief overview of the toxin content

Since a large number of decorative plant families are classified as succulents, this type of plant cannot generally be defined as toxic or non-toxic. The following brief overview provides information on some of the most famous succulents:

  • Thick-leaf plants (Crassulaceae), such as money tree, sedum plant or Kalanchoe: non-toxic to slightly toxic
  • Aizoaceae, such as living stones: slightly toxic in large quantities
  • Amaryllis family (Amaryllidaceae), like knight star: highly poisonous
  • Spurge family (Euphorbia), such as poinsettia: poisonous to highly poisonous
  • Arum family (Araceae), like lucky feather: poisonous to highly poisonous

Cacti are consistently non-toxic. However, the long, sharp thorns can cause skin injuries which, if left untreated, can develop into dangerous infections.
