Fittonia albivenis 'Jade'

Where it comes from

Six countries, not one. Kew gives the native range as Bolivia, northern Brazil, Colombia, Ecuador, Peru and Venezuela — southern tropical America.¹ Worth saying because “native to the Peruvian rainforest” is the standard line, and a 2025 genome paper repeats it.² Peru is one of six.

It is a plant of the forest floor, which turns out to be more interesting than “tolerates low light” — see below.

Naming and description

The synonymy is genuinely tangled and Kew settles it: Fittonia albivenis is the accepted name, with F. verschaffeltii and F. argyroneura both sunk into it.¹³ The RHS keeps the old names alive usefully, as two cultivar Groups — the Verschaffeltii Group for the pink-veined plants and the Argyroneura Group for the silver-veined ones, both holding an Award of Garden Merit.⁴⁵

‘Jade’ carries no registration and no patent. The RHS’s Fittonia genus page lists its complete holdings and they are those two Groups and nothing else.⁶ Justia returns eleven US plant patents for Fittonia and none is ‘Jade’⁷⁸ — and that absence means something, because ten of the eleven come from a single Dutch breeding house, so named Fittonias plainly do get patented. What I will not do is call it a trade name, because no source says so; what the searches support is that it is unregistered and unpatented, which is a narrower claim.

Fun facts

• “Tolerates low light” is the wrong description. It is a far-red specialist. A 2024 study solved this plant’s photosystem I by cryo-electron microscopy and found it red-shifted: its chloroplasts fluoresce at 753 nm against 735 nm in Arabidopsis, with “red chlorophylls” absorbing beyond the visible range.⁹ On a rainforest floor the canopy has taken the red and blue and left the far-red behind — and this plant eats what is left.
• Which means a leggy nerve plant may be responding to light quality rather than starving. Under far-red it elongates its internodes and petioles while chlorophyll falls only 7.2 per cent over twelve days.¹⁰ Stretching is not always a cry for more light.
• By the time it faints, it has already stopped working. The dramatic collapse is the turgor loss point,¹¹ and stomatal closure tracks that point rather than following it — so the plant shuts down gas exchange, and therefore photosynthesis, before the droop is visible.¹² Whether repeating it does cumulative harm has not been tested on this plant, and the page will not claim it does. But the wilt is a symptom of something that already happened, not a convenient reminder.
• The ASPCA page you want is not the obvious one. Its “Mosaic Plant” entry has a scientific-name field reading Bertolonia mosaica — a different plant in a different family, and an awkward collision, because “mosaic plant” is the RHS’s own common name for one of the two Fittonia Groups.¹³ The clean entry is “Nerve Plant”, whose field gives Fittonia verschaffeltii, a genuine synonym of this species.¹⁴ It is non-toxic.
