About the plant

Veltheimia bracteata is a species of plant. It belongs to the genus Veltheimia, which contains only one other species, Velthemia capensis. Veltheimia bracteata is commonly referred to as the forest lily, sand onion, or red hot poker. This pendant-shaped plant ranges in color from a yellowish pink to red. It is a winter flowering perennial plant, so is in full bloom when other flowers have withered away. Plants grow to be 12–18 inches (30–46 cm) in height.

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.
