Tread-softly (Cnidoscolus stimulosus) is a perennial, low-growing herbaceous wildflower. Its brilliant white flowers bloom year-round. It occurs naturally in sandhills, scrub, pine and scrubby flatwoods, and ruderal and disturbed areas. It attracts many butterflies and other pollinators. It’s easy to see how tread-softly gets its common name, and its scientific name is just as telling.
