Lamium hybridum, an originating-in-Europe perennial, occurs on roadsides or in cultivated fields. Stems, with a cross-section of a square, branch well at bases, stand erect or diagonally upward, and grow to as tall as 30cm. Leaves are opposite, broadly ovate, and heart-shaped at the base, with sharp serrations cut in anew. Blades are somewhat crepey with sparse hair and long petioles on the lower part of the stem leaves. Close to the stem top portions bear inflorescences and set about 1.5cm light red-purple, labiate flowers; the corollas comprise upper and lower parts, and the tubular parts rise, with long, dense hairs. Bloom time: April-May.
