Peperomia griseoargentea aka Peperomia Wavy Gravy

Peperomia griseoargentea is an evergreen perennial from Brazil. It belongs to the pepper family, Piperaceae. Its native habitat has a wet, tropical climate. Common names include ivy peperomia and silver leaf peperomia. Gardeners grow it as a houseplant and in containers. Its small clumps suit a desk or other limited space. The silver leaves provide the main point of interest.

The plant forms an upright clump or low rosette. Short, thick stems support its fleshy leaves and store water. NC State gives a height of 0.5–0.67 feet [0.15–0.20 metres]. Its stated width is 0.42–0.58 feet [0.13–0.18 metres]. RHS gives a broader range for both height and spread. That range reaches 1.64 feet [0.5 metres]. RHS lists two to five years to reach full size. The glossy leaves have smooth edges and no hairs. Their heart-shaped blades have a rippled, silver-green surface. NC State describes dark green veins; RHS describes reddish veins. Leaves can reach about 0.2 feet [0.06 metres] long. Small green flowers grow on thin spikes.

Give this plant bright, indirect light while it grows. RHS advises partial shade in summer and fuller light in winter. Use houseplant compost or loam that lets excess water drain. RHS lists acid, neutral, and alkaline soils as suitable. Keep the soil moist without letting it stay waterlogged. Water moderately in summer and less in winter. RHS recommends soft, lukewarm water and moderate to high humidity. Feed monthly during growth with a balanced liquid fertiliser. Its UK hardiness rating is H1B, allowing summer outdoor use. NC State lists USDA zones 10 through 12.

This species works as a foliage accent in a pot. RHS also lists it for terrariums and bottle gardens. It needs little upkeep, and regular pruning is not required. Remove old flower spikes once they have finished blooming. Seeds, softwood cuttings, and leaf cuttings offer ways to propagate it. NC State describes its care as easy.

RHS reports few pest or disease problems under suitable care. NC State advises watching for mealybugs, spider mites, and aphids. Scale, fungus gnats, and whiteflies can also occur. Too much water can cause root rot. Wet leaves can develop spots, so avoid splashing them when watering. ASPCA lists this species as non-toxic to cats and dogs. Its ivy peperomia page also lists it as safe for horses. These sources do not establish any edible use.
