About the plant

Euphorbia royleana is a species of flowering plant in the family Euphorbiaceae. It is also known as Sullu spurge, and Royle's spurge. It is a succulent and almost cactus-like in appearance, although unrelated. It grows right across the Himalaya mountains from Pakistan, India, Bhutan, Myanmar, Nepal to western China. It prefers dry and rocky slopes between 1000–1500 m altitude, but has been found up to 2000 m. Flowering and fruiting is in spring to early summer and seeding is in June to October. It is used as a hedging plant in northern India and has medicinal uses. It is an outlier of an assembly of succulent tree spurges which are otherwise confined to South Africa, East Africa and Madagascar with another outlier in the caatinga of Brazil.

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.
