Comments: Black-foot daisy is tufted and slightly shrubby. From Greek melas "black" and podos "foot" in reference to the small foot-shaped bracts subtending the ray florets which turn black when mature. Black-foot daisy is strongly drought-resistant. It is often observed with Rocky Mountain zinnia Zinnia grandiflora.
