| + | Chrysogonum (Greek-made name, golden knee or joint). Compositae. A few composites, of which C. virginanum, Linn., is a perennial yellow-fld, plant of S. Pa. and south; sometimes cult. as a border plant. It blooms in spring or early summer on sts. which become 1 ft. high, the heads being solitary and peduncled in the axils or some of them terminal: lvs. opposite and basal, ovate and mostly obtuse, crenate. Prop. by creeping rootstocks and runners. Of little merit horticulturally. |
