lathyris

Lathyris, commonly referring to Euphorbia lathyris, is a tall flowering plant in the spurge family (Euphorbiaceae). It is native to southern Europe and central Asia and has become naturalized in parts of North America and other regions. The plant forms a single erect stem to about 1–2 meters in height, with a dense rosette of long, narrow, bluish-green leaves arranged opposite in pairs around the stem. Leaves can reach up to about 40 cm in length and may wrap slightly around the stem. The inflorescence consists of small, yellow-green flowers produced in terminal clusters in late spring to early summer, followed by fruit capsules containing seeds.

Lathyris is grown as an ornamental plant in some gardens for its bold vertical habit and striking foliage. It is also reputed to deter moles and other burrowers, a use that persists in folk gardening, though scientific evidence for effectiveness is limited. Because the plant self-seeds readily, it can become naturalized or invasive in suitable climates and may escape cultivation.

Toxicity and safety: Euphorbia lathyris contains a milky latex and seeds that can be toxic if ingested. Contact with the sap may irritate skin and eyes. The plant can be hazardous to pets and livestock; handling with gloves is advised and it should be kept away from children and grazing areas.
