This long-lived perennial is also known as "snow squarestem." It is a very robust perennial wildflower found throughout Florida. It has very showy white flowers with black flecks. It does go dormant in the winter. When it gets leggy, it is good to prune a little. It likes part sun to full sun, moderately salt tolerant and moist to dry soil. It will reseed itself. It is heavily used by butterflies, skippers, bees, and wasps for nectar.
