Ficus elastica 'Melany'

Cultivar development and species origin

Ficus elastica is native from the eastern Himalaya through parts of southern China and mainland Southeast Asia to western Malesia. In warm, humid forest it can become a very large evergreen tree, send down aerial roots and begin life on another tree before rooting into the ground.

The species’ milky latex was once tapped as a source of rubber, although commercial production later shifted mainly to Hevea brasiliensis. ‘Melany’ was selected as a compact, freely branching form with relatively small leaves and close leaf spacing. Its compactness remains relative to a species that develops a substantial woody tree structure.

Care for dark rubber-plant foliage

Roots and substrate: The thick leaves of the plant postpone obvious wilting, so judge moisture from the potting mix instead of waiting for the crown to droop. Once the surface layer of an open loam-based mix has dried, water the whole root ball and drain it completely.

Light: Abundant indirect light supports compact growth with little bare stem between the leaves. Introduce mild direct sun gradually because newly delivered leaves can scorch after an abrupt increase.

Propagation: A cut just above a node can produce one or more side shoots, depending on the strength of the plant. Root younger stem cuttings, or encourage roots on a thick stem by air layering before cutting it from the plant.

Feeding: Keep the roots away from chilling temperatures and shield the plant from cold draughts. Fertilise moderately while new leaves are developing.

How to recognise and fix problems

Yellowing, dark patches and leaf drop on ‘Melany’ commonly involve excess water, low light or chilling. A heavy pot with a wet centre and soft roots points to root stress. Empty standing water and let the root zone dry partially before watering again, while protecting the root ball from cold.

Dry crisp margins and inward-curling leaves are more consistent with drought or salt accumulation. Soak a dry throughout root ball, let it drain and flush the mix if fertiliser residue has built up. Small pale new leaves suggest inadequate light, depleted roots or insufficient nutrition, so correct light and root health before feeding more heavily.

The red sheath around a developing leaf is normal. A sheath or stem that turns black, soft and spreading is not. Keep ‘Melany’ apart from the collection and keep the affected area dry while assessing the stem and roots for rot.

Thrips can scar or deform unfurling leaves; mites create stippling, and scale or mealybugs form bumps or cottony clusters. Mineral spots sit on the glossy surface and wipe away, unlike scale insects attached firmly to the tissue. Clean the leaves first, then inspect again before treating.

Ficus elastica ‘Melany’ is toxic to people and pets

• Keep this plant away from children, cats and dogs, and avoid contact with its milky sap.
• The latex contains ficin and psoralens, which can irritate the mouth, digestive tract, skin and eyes.
• Exposure may cause mouth irritation, drooling, vomiting, stomach pain or a skin rash. Contact a veterinarian or medical professional if symptoms develop or persist.

Where does the name Ficus elastica come from?

Classical Latin ficus means fig. Elastica refers to the latex once investigated as a rubber source.

Carl Linnaeus established the genus Ficus in 1753 in Species Plantarum, page 1059; Joseph Pitton de Tournefort had proposed the name.

Jens Wilken Hornemann first described Ficus elastica in 1819 in Supplementum Horti Botanici Hafniensis, page 7; William Roxburgh had proposed the name.
