Watermelon peperomia , Peperomia argyreia plant
Peperomia argyreia, the watermelon peperomia or watermelon begonia, is a species of flowering plant in the family Piperaceae, native to northern South America, including Bolivia, Brazil, Ecuador, and Venezuela. The plant is not closely related to either watermelons or begonias. These terms relate to the shape, markings and texture of the leaves. Growing to 20 cm (7.9 in) tall and broad, it is a perennial with asymmetrical oval green leaves, slightly fleshy, strikingly marked with curved silver stripes, and red stems. Tiny green flower spikes appear in summer.
Prefers temperatures of 65-75ºF (18-24ºC), and no lower than 50ºF (10ºC).
A bright room with the plant placed in a shaded spot is ideal, without direct sunlight. In their natural habitat they reside undercover within forests with some sun and shade so we need to try and replicate this. Sitting back from a west, east or even south facing window is best.
It’s important not to water these plants too much or underwater them. Over-watering can cause rot and under-watering will make them wilt. To get watering just about right, allow the soil to dry to the touch at the top and then water thoroughly, but much less during winter.
A peat based soil is best used that drains well. 2 parts peat and 1 part perlite is a good mix.
