The Watermelon Peperomia earns its name from the striking silver-and-green striped, teardrop leaves that look just like watermelon rind. It's compact, striking and easy to grow.

Light

Bright, indirect light keeps the striped pattern crisp and the plant compact.

Water & humidity

Semi-succulent, so let the top layer dry between waterings โ€” it's far more tolerant of dry than wet.

In the terrarium

Suited to open or airy terrariums. Its upright, bushy habit makes a lovely mid-height feature; avoid the saturated conditions of a sealed jar.

Tip: Wipe dust off the broad leaves occasionally so they can photosynthesise and keep their shine.

Common problems

  • Drooping stems = overwatering or roots sitting wet.
  • Small, dull leaves = too little light.

Is Watermelon Peperomia a terrarium plant?

Why are my Watermelon Peperomia leaves drooping?

Usually overwatering. Let the substrate dry down and check the roots aren't sitting in water.
