Euphorbia virgata (Leafy spurge) is a non-native California perennial in the Euphorbiaceae family, recognized by tall habit with large crescent-shaped glands and yellow bracts.

Leafy spurge is a naturalized perennial herb found in southern North Coast, eastern Klamath Range, California Range, and North Coast Ranges in fields and pastures at elevations below 1,400 meters. Flowering from May to August, this plant produces small yellow-green flowers in distinctive umbel-like clusters with triangular-ovate bracts. Growing with erect stems 30 to 80 centimeters tall that emerge several from the base, it has a clumping growth habit with glabrous to slightly hairy stems. Its leaves are linear to lance-shaped, 2 to 6 centimeters long, with proximal leaves alternating and the uppermost leaves arranged in whorls. The fruit is a smooth, spherical capsule 3 to 4 millimeters long, containing small gray to tan seeds.

How to tell it apart

vs Croton: Euphorbia bleeds milky white latex and packs its flowers into a tiny cup (cyathium) rimmed with nectar glands; Croton has watery sap, stellate or scaly hairs, and ordinary small separate male and female flowers.; vs Stillingia: Euphorbia flowers sit in a gland-bearing cyathium; Stillingia bears its flowers in a spike with a pair of glands flanking each subtending bract and has no cyathium cup.; vs Ditaxis: Euphorbia has latex and the cyathium; Ditaxis has clear sap, 5-parted petaled male and female flowers, and 2-forked (malpighiaceous) hairs.; vs Asclepias: Both ooze milky sap, but Euphorbia's minute flowers cluster in a cyathium and ripen into a 3-lobed capsule; milkweeds have showy 5-parted flowers with a crown and paired follicles of plumed seeds.; vs Polygonum: Prostrate mat spurges leak milky sap when torn and have paired stipules with opposite leaves at the nodes; knotweeds have clear sap and a papery sheath (ocrea) wrapping each node.
