Overview

Peperomia caperata is a low-growing, clumping evergreen herb with a rosette to mound-like habit; it may form an upright bushy clump and can also grow as an epiphyte in its native habitat. It is an evergreen perennial herb.

Origin and habitat

Peperomia caperata is native to Brazil, while some sources describe its native range more broadly as South America or Central and South America. It occurs in South American jungle environments, where it can grow as an epiphyte and in places shaded by trees. It is associated with tropical environments and is usually grown as a houseplant in temperate regions.

Characteristics

Sources differ on mature height, placing it at about 15–20 cm, while mature spread is 15–20 cm. Its growth rate is reported to be moderate. The leaves are thick and somewhat succulent, heart-shaped, and deeply wrinkled or grooved; the species is commonly dark green, while selections may be burgundy, silver, or nearly black, and 'Luna Red' has dark red, deeply grooved leaves. The very small greenish-white, cream-white, or white flowers are densely borne on slender upright spikes that may be tail-like or club-like; sources describe flowering from spring through fall, with some specifically reporting summer flowering.

Light

Bright indirect light or filtered medium light is preferred, though the plant can tolerate low light briefly; strong direct light should be avoided because it can fade the leaves or weaken the plant, while the RHS advises that light can be increased to full light in winter.

Watering

Water moderately to sparingly in a well-drained medium, allowing the surface soil or medium to dry slightly between waterings; avoid prolonged wetness and overwatering to reduce the risk of root rot, and reduce watering in winter.

Humidity and airflow

Peperomia caperata prefers high humidity. It is reported to need little air movement.

Temperature and dormancy

A single source reports an ideal temperature of about 16–24 °C and a minimum of about 15 °C, so sources are few for these temperature figures. Sources differ on the reported hardiness zone. It is generally described as frost tender; keep above freezing.

Growing medium and mounting

Use a loose, porous, well-drained medium; houseplant potting mix may be used, and sources also mention humus, gravel, and peat mixtures. The RHS reports that loam or sandy soil may be used and that soil reaction can range from acidic through neutral to alkaline.

Feeding

A balanced liquid fertilizer is reported to be applied monthly from spring through summer.

Propagation

Propagation can be done in spring or summer using leaf cuttings with petioles, leaf cuttings, or stem-tip cuttings; mature seeds can also be sown.

Common problems

Whiteflies, mealybugs, and spider mites may occur, although the RHS reports that pests are generally uncommon. Root rot, leaf spot, and gray mold may occur. Overwatering or persistently wet soil can lead to root rot; very dry soil and strong drafts are also unsuitable, while strong direct light may fade the leaves and weaken the plant. It is sensitive to frost and low temperatures and should be kept away from freezing conditions; sufficiently low temperatures make it unsuitable for general outdoor cultivation.

Identification

'Luna Red' is reported to be distinguished by dark red leaves with deep grooves; Peperomia caperata also has heart-shaped, wrinkled leaves and upright flower spikes.
