Peperomia argyreia aka Watermelon Pepper


Peperomia argyreia, known as the watermelon peperomia, is a species of flowering plant in the family Piperaceae, native to northern South America, including Bolivia, Brazil, Ecuador, and Venezuela. It grows to 20 cm (7.9 in) tall and broad, with asymmetrical oval green leaves, slightly fleshy, strikingly marked with curved silver stripes, and red stems. Tiny green flower spikes appear in summer and it is valued in cultivation as a houseplant at a minimum temperature of 10 °C (50 °F), in bright light but not direct sun, with the Royal Horticultural Society’s Award of Garden Merit. In India and Southeast Asia, it is found as a small, groundcover-like herb, with glossy leaves and crimson stems resembling tiny watermelons. It stands at a maximum height of 5 in (12 cm) and its flower isn't particularly fragrant or attractive. The fruits of Watermelon Peperomia have a peppery taste and have traveled one of the longest distances ever recorded for a plant, over 3000 miles to an island in the middle of the Atlantic ocean, while stuck to a bird's feet.

How to care for Watermelon Pepper


Even if you don't have a green thumb, you can successfully care for Watermelon Pepper due to its easy-going nature.


Watermelon Pepper should be watered regularly, allowing the soil to dry out between waterings.


Watermelon Pepper loves a well-draining soil. Perlite and vermiculite help with drainage, while coco coir adds organic matter, so a good potting soil mix will have all three. You can improve store-bought soil by adding some perlite to it.


To ensure optimal growth, the Watermelon Pepper prefers bright diffused light for 6-8 hours each day. Insufficient light can result in slow growth and leaf drop, so it's important to find a well-lit location for this plant. Place it near a window, within a distance of 1 meter (3 feet), to enhance its potential for thriving.


During the wintertime, it's common for Watermelon Pepper to go dormant and their growth may slow down, so waterings should be spaced out more.

Repotting the Watermelon Pepper is necessary either when it has doubled in size or once every year, whichever happens first. With fresh potting soil replenished annually, the plant will receive all the necessary nutrients, rendering the use of fertilizer unnecessary.
