Euphorbia lathyris is an annual or perennial herb that is not native to California.
There is a high risk of this plant becoming invasive in California according to Cal-IPC.
[pfaf.org] Toxicity: The sap contains a latex which is toxic on ingestion and highly irritant externally, causing photosensitive skin reactions and severe inflammation, especially on contact with eyes or open cuts. The toxicity can remain high even in dried plant material[200]. Prolonged and regular contact with the sap is inadvisable because of its carcinogenic nature[214]. The seed is also poisonous[76].
