Introduction
Peperomia has round, smooth, dark green leaves and short, somewhat brittle stems, seldom growing taller than 12 inches. Quickly growing into spreading clumps, peperomia is ideal for tropical groundcover use, as well as container culture or raised planters. It also makes a durable houseplant and will cascade over the side of a hanging basket.

Use and Management
Growing in partial to deep shade, peperomia will thrive in moist, rich, organic soils or less fertile sandy soils. Although preferring high humidity, it must have well-drained conditions to avoid stem and root rot. Plant on 12 to 18 inch centers for quick establishment as a ground cover. It is best to err on the dry side when growing peperomia.
A few available cultivars include 'Alba', young growth entirely white-yellow, marked with bright red; 'Albomarginata', grey-green leaves with silvery border; 'Albomarginata Minima', dwarf form of the preceding; 'Minima', compact plant, leaves one to two inches long; and 'Variegata', grey-green blotched green leaves with a broad, creamy-white margin.
Propagation is by cuttings which root easily or by division.
Pests and Diseases
Peperomia's main pest problem is mites.
Peperomia is susceptible to stem and root rots and leaf spot diseases.
