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