Difficult One of the harder ones, and one of the reasons the diagnosis tool exists.

Toxicity is partly unassessed

  • Listed as non-toxic to cats by ASPCA.
  • Listed as non-toxic to dogs by ASPCA.
  • Not assessed for people. RHS publishes no harm statement for this plant. That is not a finding of safety: none of the sources read for this site gives an answer either way. Treat it as unknown.

How it usually goes wrong

Dry, curled edges on leaves near a heater

A yellow halo sits just inside the brown edge on the nerve plant, and new leaves often come in already tipped with brown during the heating season.

Dry air takes water from the leaf surface continuously, and the tissue at the edge is last in the queue for what the roots send up. Penn State Extension notes there is no single humidity figure that suits every indoor plant.

Telling it apart: What else in the room changed. Edges that browned when the radiators came on point at the air rather than at the watering.

Penn State ExtensionNerve plant brown leaf tips and edges: causes
New leaves are smaller than the old and further apart

Compare this year's growth on the nerve plant with last year's: new leaves are smaller, thinner and a paler green, and the gap below each one is longer.

Light is the budget every other process is paid from. Under the partial shade its source names, the plant spends down reserves and shows it in thin, pale growth.

Telling it apart: Whether it leans. A plant reaching for a window is answering a light question, and it leans before it pales.

The outer leaves turn yellow and hang

Colour goes before shape on a nerve plant. The outer leaves yellow evenly, stay soft to the touch, and the compost two inches down is still wet from the last watering.

Kept wetter than the moist but well-drained its source describes, the root tips die back. A plant with fewer working roots cannot drink, which looks from above exactly like one that has not been watered.

Telling it apart: The smell. Healthy compost smells of earth; compost that has been wet too long does not.

About the plant

Fittonia albivenis is a species of flowering plant in the family Acanthaceae, native to the rainforests of Colombia, Peru, Bolivia, Ecuador and northern Brazil. An evergreen perennial, it is notable for its dark green foliage with strongly contrasting white or red veins. It is commonly called nerve plant or mosaic plant. In temperate regions where the temperature falls below 10 °C (50 °F) it must be grown as a houseplant.

What this does not cover

The figures above are what published sources say, not measurements of the plant in your room. They say nothing about your pot size, your water, the season, or how far from the glass the plant stands, and those decide more than any figure here does.

Humidity has no species figure because no source read for this site publishes one, and the only temperature published for this plant is a cold floor. The simulator fills those gaps with general figures for its kind of plant, marked as general and listed on how we read sources. Where a toxicity row says the plant was not assessed, that is the absence of a finding and not a finding of safety.

If something is already wrong, the diagnosis tool asks about the soil, the window and the watering, which is where the answer usually is.
