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

Pale dry areas across the upper leaves only

Affected tissue goes pale and then papery, and the boundary follows where the light falls rather than the shape of the leaf.

Its source names full sun, yet a leaf grown in lower light has thinner tissue than one grown in sun, and it scorches if moved into strong light in one step.

Telling it apart: Which side. Damage confined to the lit side is light; damage spread evenly is not.

Swollen, darkening leaves that come away at a touch

A leaf of the Mexican snowball that should be firm gives under light pressure and stays dented, and those beside it follow within days.

Its source describes well-drained soil. Past that, a plant built to survive drought has no mechanism for shedding the excess, and the tissue breaks down rather than simply looking unwell.

Telling it apart: Press one gently. A dehydrated leaf is leathery and springs back; a waterlogged one stays dented.

The whole plant sags between waterings

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

Soil described as well-drained still has to hold some water. Once it is dry right through, the roots have nothing to take up and the leaves lose the pressure that holds them firm.

Telling it apart: How fast it recovers. A thorough watering lifts a thirsty plant within hours; roots that are damaged do not respond.

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.
