Euphorbia ritchiei is a Kenyan caudiciform species that forms clumps of knobbly, spiralled stems rising from a swollen tuberous base, giving it a geometric, almost tessellated look even before the seasonal bracts appear. During active growth it may carry small fleshy leaves, while mature plants can also produce bright pink bracts around the cyathia, usually later in the season.
It prefers bright light to full sun, a very open mineral substrate, moderate watering only while growing, and an almost dry rest in winter. Warm temperatures around 18–28 °C suit it best, and cold plus moisture is the combination most likely to cause losses.
Like all Euphorbia, it contains caustic milky latex, so gloves and sensible handling are strongly advised around skin, eyes, pets, and children.
