Ficus lyrata Warb.

Where it comes from

Kew gives the native range as western and west-central tropical Africa — eleven countries: Benin, Cameroon, Gabon, Ghana, Guinea, Guinea-Bissau, Ivory Coast, Liberia, Nigeria, Sierra Leone and Togo.¹ Worth saying because the phrase that circulates, “Cameroon west to Sierra Leone”, quietly drops three of them, and Gabon is the one that matters: it puts the species across the Equator, which is why Kew’s own gloss reads “W. & W. Central” rather than just west.¹ It is a lowland rainforest plant.²

The detail almost nobody repeats is Kew’s lifeform line: “It is a hemiepiphytic tree.”¹ So it does not, in the usual case, start in the ground. A seed germinates up in the crown of another tree and the plant grows downwards to reach soil — which is what those stubby roots on the trunk are for.

Whether it goes on to strangle its host is a different question, and the answer is that nobody has documented it for this species. UF/IFAS notes it makes aerial roots but “not as many as on some other Ficus”, and one horticultural treatment describes solitary trunks with no aerial roots at all.³⁴ Calling it a strangler fig is a reasonable guess about a hemiepiphyte and not something anyone has written down.

Height in the wild is the number to be careful with. Five sources cluster around 12-16 m and Missouri Botanical Garden alone gives 18-30 m,⁵³²⁶ but every one of the lower figures describes a cultivated or garden tree and the higher one is uncited. A hemiepiphyte in West African lowland forest could plausibly reach the canopy; nobody has published a measured wild height. The honest version is “a forest tree, and the pot is what keeps it small”.

Naming and description

Otto Warburg published the name in 1894, in Botanische Jahrbücher für Systematik 20: 172; IPNI dates the publication to 16 November of that year and records Warburg’s original distribution note as “Afr. trop. occ.”¹⁷

Lyrata means lyre-shaped, and it is arguably the wrong word — a lyrate leaf is pinnately lobed with an enlarged terminal lobe, and this leaf is not lobed at all. The botanical term for its actual shape, obovate with a waist, is pandurate: fiddle-shaped. Which is the joke of the synonym. The only name POWO lists under F. lyrata is Ficus pandurata Sander (1903) — the more accurate name, and illegitimate, because Ficus pandurata Hance had been published in 1862 for something else.¹⁸ Hance’s plant is still an accepted species today: a subtropical Chinese and Indo-Chinese shrub.⁹ So the two names are both live, pointing at different plants on different continents, and “F. pandurata” still turns up on fiddle leaf fig labels — where it will lead a careful reader to the wrong plant.

The blade reaches about 45 × 30 cm, thick and leathery, dull green above, with veins deep enough to make the surface look quilted.¹⁰¹¹⁶ The RHS gives the species as an evergreen tree to 5 m or more under glass.¹¹

One correction worth making, because the hobby has it backwards. ‘Bambino’ is not a marketing name for a young plant. It is US Plant Patent PP9323, filed December 1994 by Eduard J. M. van der Knaap, and the patent says it was discovered in 1992 “as a whole plant mutation of unknown causation” among Ficus lyrata in the greenhouses of the De Wilgenlei nursery at Bleiswijk in the Netherlands. Its leaves run about 14-21 cm long against the species’ 45, and they are thicker.¹² There is a later patent for ‘BAMBINO2’ from the same breeder,¹³ the RHS carries that one with plant breeders’ rights,¹⁴ and “Little Fiddle” is Costa Farms’ name for the same plant.¹⁵ A small fiddle leaf fig is sometimes a small plant and sometimes a genuinely different one.

Fun facts

• Leaf drop after a move is arithmetic, not sulking, and the sums were done in the nursery. The mechanism is the light compensation point — the light level at which a leaf’s photosynthesis exactly pays for its own respiration. Plants grown in full sun have compensation points nearly three times higher than shade-grown ones, so in a living room their leaves cost more than they earn and get shed.¹⁶ A sun leaf cannot be converted into a shade leaf — it has two palisade layers where a shade leaf has one — so the plant has to grow replacements, which is why the drop runs for months.¹⁶ The same work found up to a 42 per cent difference in leaf loss between clones, and that acclimatising for as little as twelve weeks before sale measurably reduced it.¹⁶¹⁷ The move is not the cause; the drop in light across the move is, and its size was set before you bought the plant.
• Do not trim the big leaf off a cutting. This is the one propagation finding that names this species: UF/IFAS tested F. lyrata cuttings and found that “removing a large portion of the leaf resulted in lower root grades” — keeping the whole leaf rooted best.¹⁸ The usual advice to cut the leaf down to reduce water loss is, for this plant, backwards.
• The brown spot everyone calls Xanthomonas is probably not. UF/IFAS’s disease guide for ornamental figs carries a photograph captioned “Pseudomonas leaf spot on Ficus lyrata” — water-soaked, randomly spaced lesions. Its Xanthomonas section names only F. benjamina and F. retusa as hosts.¹⁹ Neither is a thing you can treat at home, but it is worth knowing that the confident diagnosis on the forums is attached to the wrong organism for this species.
• It fruits in cultivation and the figs are always sterile. Fig pollination is obligate and species-specific — each Ficus has its own agaonid wasp — and the wasp for this one has not travelled. Surveys in Hawai’i and in Borneo both record fruit but no viable seed.⁴²⁰ Which is why POWO’s introduced range runs to only three regions: it cannot naturalise without its pollinator.¹ I could not establish which wasp species it is — the subsection’s pollinators are in the genus Agaon, but naming a species would be a guess.
• “The ASPCA says the fiddle leaf fig is toxic” is a miscitation, and a funny one. The ASPCA page titled “Fiddle-Leaf” is Philodendron bipennifolium — an aroid, with insoluble calcium oxalates.²¹ Anyone citing it for this fig has cited a completely different plant in a different family. The ASPCA’s actual entry for the genus gives the toxic principles as the enzyme ficin and the furanocoumarin psoralen, with gastrointestinal and dermal irritation.²² NC State’s own page for F. lyrata repeats the calcium oxalate line, which contradicts NC State’s own genus page and looks like the same confusion again — this page follows the genus.¹⁰²³ The RHS is blunter than either and calls it a skin allergen: gloves when you are pruning.¹¹
