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

Buds form and fall before they open

The pink jasmine sets buds normally, and they yellow at the stalk and drop before they colour.

Its source places it in full sun, partial shade. A bud formed in that light and then turned away from it, or left in drying compost, is the first thing the plant gives up.

Telling it apart: When the buds dropped. Within days of a move or a dry spell is the change; buds that drop with nothing changed point at uneven watering or pests on the buds.

Dry, curled edges on leaves near a heater

Leaves on the side of the pink jasmine nearest a heater or vent brown at the edges while those on the far side stay clean.

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: Where the plant stands. Browning concentrated on the side facing a heater points at the air.

Leaves soften and curl inward

The pink jasmine hangs evenly all over, and the compost has gone pale and hard. Nothing is spotted or rotten; the plant is simply short of water.

Its source describes well-drained soil. Below that the cells lose pressure, and pressure is what holds a leaf out straight.

Telling it apart: Whether water runs straight through. Compost dried hard sheds water down the sides, which is itself a sign of drought.

Whitened areas where the sun falls longest

The pink jasmine shows pale, dry patches only where direct sun reaches, often with a sharp edge between damaged and healthy tissue.

Sun through a window on a still day heats a leaf far above the air around it. Its source describes full sun, partial shade; the glass adds the heat that does the damage.

Telling it apart: The edge of the damage. Scorch has a sharp boundary; rot and infection have a soft, spreading one.

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.
