Peperomia

Common name: Peperomia · Radiator plant

Peperomia is a large genus of more than a thousand species of mostly small, compact plants native to tropical and subtropical regions worldwide. Many store water in their thick, fleshy leaves, giving them a semi-succulent character. They are prized houseplants for their decorative foliage and small footprint.

Fun facts

  • The genus contains over 1,000 species.
  • The name comes from Greek words meaning 'resembling pepper' — it is related to black pepper.
  • Most species are non-toxic, making them popular pet-safe houseplants.
  • The slender flower spikes look like rat tails and carry no petals.
