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

Also called African Daisy, Gerber Daisy, Gerbera Daisy, Transvaal Daisy and Veldt Daisy.

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

Edges of the leaves brown while the middle stays sound

The Barberton daisy browns at the very tips first, and the brown line creeps back along the edges over weeks. The tissue is dry and brittle, not soft.

Penn State Extension cites ASHRAE's recommended indoor range of 30% to 60% relative humidity; a heated room in winter drops below it. Air that dry pulls water from the leaf faster than the roots replace it, and the margins are furthest from the supply.

Telling it apart: Look at the pot rim and the soil surface. A white crust points at a build-up from tap water or feed rather than at the air. Penn State also reports misting and pebble trays do little to the humidity around a plant.

Flowering stops while the foliage carries on

The Barberton daisy looks well in every other respect: green, firm and growing. What is missing is the flowering.

Buds are formed only when the plant has energy to spare. Its source places it in full sun, and in less light than that the surplus that pays for flowers is missing.

Telling it apart: The spacing of the newest leaves. Stretched growth means the light is short; normal spacing points at timing or feeding.

Whitened areas where the sun falls longest

Scorched leaves on the Barberton daisy turn from pale to brown and brittle, and the damage stops where the shade of another leaf fell across it.

Its source names full sun, so the light itself is not the fault. Foliage that formed in a dimmer room is thinner than foliage grown in sun, and the side turned suddenly to strong light bleaches before it can adjust.

Telling it apart: Whether the undersides are affected. Light damages what it reaches and nothing else.

Wrinkling rather than yellowing

Posture goes before colour. A thirsty Barberton daisy looks deflated rather than diseased, and the compost has shrunk away from the side of the pot.

Water held in the cells keeps a leaf rigid. With the compost dry beyond what its source describes as well-drained, that water is used and not replaced.

Telling it apart: The weight of the pot. Light and sagging is thirst; heavy and sagging is not.

About the plant

Gerbera jamesonii is a species of flowering plant in the genus Gerbera belonging to the basal Mutisieae tribe within the large Asteraceae family. It is indigenous to South Eastern Africa and commonly known as the Barberton daisy, the Transvaal daisy, and as Barbertonse madeliefie or Rooigousblom in Afrikaans. It was the first species of Gerbera to be the subject of a scientific description, studied by J. D. Hooker in Curtis's Botanical Magazine in 1889.

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.
