Overview

Ficus elastica is a large perennial evergreen tree that can grow as a strangling hemiepiphyte in the wild, often developing aerial and buttress roots; in temperate regions it is commonly grown as a large indoor foliage plant.

Origin and habitat

Sources differ slightly on the boundaries of its native range, describing it as extending from southern Asia into Southeast Asia, including Nepal, Bhutan, northeastern India, Bangladesh, Myanmar, Thailand, Yunnan in China, Malaysia, and Indonesia. It occurs in hill forests, especially on cliffs and limestone mountains, and young plants may grow on other trees in natural habitats. Native to tropical Asia, it can grow in dry to moist tropical environments; it is grown outdoors as an ornamental tree in tropical and subtropical areas and commonly as an indoor plant in colder regions.

Characteristics

Sources differ on mature height, with the limited evidence suggesting about 3000–4000 cm; a single source reports a mature spread of about 100–150 cm. It is generally reported to grow quickly, with large, thick, leathery, glossy, broadly elliptic to elliptic leaves with entire margins; sources differ on leaf dimensions, and new leaves are enclosed by a sheath-like structure that falls away after they mature. Its flowers depend on a specific fig wasp for pollination and lack bright colors or strong fragrance for attracting general pollinators; flowering is rare indoors. Sources differ in describing the fruit, but characterize it as a small, yellow-green, elliptic fig that can become yellow in mature tropical conditions.

Light

Sources differ in recommending bright indirect light, partial sun, or sun; indoors, bright filtered light is suitable, while excessively strong direct summer or afternoon sun should be avoided because it can damage the leaves.

Watering

Water regularly and moderately during active growth, watering thoroughly after the surface of the medium dries while avoiding prolonged waterlogging; reduce watering in winter or during dormancy. It has some drought tolerance but grows better under moist tropical conditions.

Humidity and airflow

Ficus elastica prefers high humidity and is generally reported to need little air movement.

Temperature and dormancy

A single source reports a minimum temperature of about 12.8 °C. It is generally described as frost tender; keep above freezing.

Growing medium and mounting

For containers, use a well-drained indoor plant potting mix or a soil-based potting medium; loam across acidic, neutral, or alkaline conditions is also supported, provided it remains moist but well drained.

Feeding

Feed regularly during the growing period; a high-nitrogen fertilizer is recommended, with another source likewise recommending liquid fertilizer from spring through autumn.

Propagation

It can be propagated by cuttings or layering; air layering can involve wounding the stem, applying a rooting treatment, wrapping it with moist sphagnum moss, and separating and planting it after roots form.

Common problems

Potential pests include scale insects, mealybugs, thrips, greenhouse red spider mites, and, according to another source, aphids. It may develop honey-fungus-related disease, while poor drainage or watering management can also lead to root rot. Avoid overwatering; strong direct summer sun can scorch leaves, while excessive feeding can contribute to excessive plant size and congested roots. It is sensitive to frost and cold and is unsuited to cold drafts or strongly turbulent air; intense summer or afternoon direct sunlight can also damage its leaves.

Identification

Ficus elastica can be recognized by its large, thick, glossy leaves and the sheath-like stipules around new leaves, which often have a reddish tint. Damaged stems and branches exude sticky white latex, and mature wild plants commonly develop numerous aerial and supporting roots.
