This compact, trailing houseplant is adored for its striking foliage: deep green leaves with light, parallel stripes that mimic the pattern of fine pinstripes. Its easy-going nature and ability to thrive in small spaces make it a perfect addition to any indoor garden, especially for those seeking a low-maintenance plant with plenty of personality.

Scientific Name
Peperomia tetragona (parallel peperomia, referencing the plant’s striped leaf pattern)

Previously referred to as Peperomia puteolata. Commonly called the Parallel Peperomia for its distinct leaf stripes.

Common Name(s)
Parallel Peperomia, Radiator Plant

Origin
Native to South America, specifically found in tropical regions of Brazil and Bolivia.

Light
Thrives in bright, indirect light but can adapt to medium light conditions. A splash of morning or evening sun in autumn and winter can boost growth. Avoid prolonged direct sunlight, as it may scorch the leaves.

Water
Thoroughly water once the top third of the soil has dried out. Ensure you don’t leave the plant or leaves wet, as this can cause rot. Reduce watering frequency during autumn and winter.

Humidity
Prefers moderate to higher humidity levels. Will appreciate misting, a humidity tray, or placement in humid areas like the kitchen or bathroom. Ensure adequate ventilation in less humid locations to prevent rot.

Soil
Requires a dense, well-draining potting mix. A mix designed for cacti and succulents works well. Repot every 2–3 years in spring as the plant grows.

Food
Feed every four waters during the growing season, reducing to every six or seven in autumn and winter. Pre-water the soil before applying fertiliser to protect the roots.

Temperature
Ideal range is 18–26°C. Protect from cold drafts and temperatures below 12°C in winter.

Pet-safe
Yes, but too much nibbling won’t be good for pets, small humans, or the plant itself.

Sprouts Top Tips
If your plant is in a darker location, poke the soil gently with a chopstick or similar to provide ventilation and mimic the actions of earthworms. This will help reduce the risk of root rot.

Extras
Peperomias can be propagated from a single leaf: trim off a healthy leaf, cut it in half, and place it onto soil. With a bit of patience and a warm spot, your peperomia will take root and grow into a whole new plant.
