Frequently Asked Questions
Yes, the popular Christmas poinsettia (Euphorbia pulcherrima) is one of the most well-known species in the Euphorbia genus.
No. The genus is incredibly diverse. While many are succulent (like the African milk barrel), others are herbaceous plants, shrubs, or trees (like the candelabra tree).
The milky latex contains diterpene esters which are strong irritants to skin and mucous membranes, and can be toxic if ingested, causing severe gastrointestinal distress.
It is named after Euphorbus, the Greek physician to King Juba II of Mauretania (c. 50 BC – c. 23 AD), who is said to have used a plant of this genus medicinally.
