Chrysogonum australe

Common Names

Green And Gold, Golden Star, Golden Knee

Summary

Chrysogonum australe is a southern creeping perennial native to the Southeastern United States, forming a low, mat-forming groundcover about 2–6 inches tall. It features dark green, opposite, oval leaves with light pubescence and crenate margins, and bright yellow, daisy-like flowers on fuzzy stalks that appear in mass for much of the growing season.

Thrives in soils ranging from dry to moist, provided drainage is good, and tolerates low to medium water. It prefers dappled or morning light, with some sun possible when moisture is sufficient. Commonly used as an ornamental, low-maintenance groundcover in Southeastern gardens in partially shaded sites, it spreads by stolons or rhizomes to form a dense mat, with plants typically spaced about 12–18 inches apart when establishing. Hardy in USDA zones 7–8, and can be propagated by division or seeds.
