How to Identify Wild Chrysanthemum? Master These Features to Recognize It Easily
I. Stems and Leaves
The stems of wild chrysanthemum are prostrate or upright. The stems and branches bear sparse hairs, with more hairs on the upper parts and on the flowering branches. The middle stem leaves are long ovate, elliptic-ovate or ovate, with pinnate shallow lobes or divisions and serrated edges, and a nearly heart-shaped or truncated base; both surfaces are almost the same color, light green, or both surfaces olive-colored after drying.
II. Flowers
The wild chrysanthemum has flower heads (capitula) 1.5-2.5 cm in diameter, mostly arranged at the tips of the stems and branches in corymbose panicles, or rarely in corymbs. The involucre has about 5 layers: the outer layer is ovate-triangular or ovate, the middle layer is ovate, and the inner layer is long elliptic. The involucral bracts are all white or brown in color, with blunt or rounded tips. The ligulate florets are yellow. The flowering period is from June to November.
