Peperomia rotundifolia aka Yerba Linda

Peperomia rotundifolia is an evergreen perennial in the pepper family, Piperaceae. Common names include round leaf peperomia, trailing jade, and jade necklace. It grows as an epiphyte and has a creeping habit. NC State places its native range from Mexico through tropical America. This includes the West Indies and parts of South America. The RHS also lists South Africa within its range.

This small plant forms low mats and sends out trailing stems. The RHS describes plants around 0.1 feet (0.03 metres) tall. Its size guide allows heights up to 0.33 feet (0.1 metres). Spread ranges from 0.33–1.64 feet (0.1–0.5 metres). NC State describes trails reaching 1 foot (0.3 metres) long. Growth is slow, with maturity taking two to five years. The thin, fleshy stems have a brown tint and fine hairs. Round leaves are thick, soft, and bright green. Pale green veins mark their surface. Leaves reach about 0.03 feet (0.01 metres) across.

Small yellow flowers grow on short spikes rather than broad blooms. The RHS reports flowering through all seasons of the year. NC State notes that plants seldom bloom indoors. The leaves and trailing form provide most of its display. Hanging baskets let the stems trail over the edge. Its compact form also suits homes, offices, greenhouses, and conservatories. It can serve as a small accent plant.

Give it bright light without direct sun while it grows. The RHS advises moving it into full light in winter. Use houseplant compost that stays moist but drains well. Both sources list loam and sand as suitable soils. Water moderately in summer and cut back in winter. The RHS favors lukewarm, soft water for watering. Feed monthly with balanced liquid fertilizer from spring through summer. High humidity suits it, though it tolerates normal indoor conditions. Keep it away from cold drafts. The RHS rates it H1B; NC State lists USDA zones 10–12. It needs no pruning, and summer stem cuttings offer propagation.

The RHS reports few pest or disease problems. NC State warns of mealybugs, root rot, cutting rot, and ring spots. Dry soil or low humidity can cause leaves to curl. Too much water can turn the leaves yellow. ASPCA lists it as non-toxic to cats, dogs, and horses. This safety listing does not establish that people can eat it.
