Its flowers are bright lemon-yellow and can bloom throughout the year, but late spring is usually its best bloom time. It occurs naturally in moist flatwoods, sandhills and ruderal areas. It is considered a near-endemic species as it occurs only in Florida and limited parts of southern Georgia. It is attractive to bees.

Also known as Largeflower jointweed, Sandhill wireweed (Polygonum nesomii) is a deciduous woody shrub that produces an abundance of spike-like flowering clusters. It is mostly a summer and fall bloomer, with October being its most abundant blooming time, but year-round blooms are not uncommon. Sandhill wireweed is endemic to Florida. It occurs nowhere else in the world.
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.
False rosemary (Conradina canescens) is a robust, evergreen flowering shrub that typically blooms from March through November, but can occur year-round. It occurs naturally in sand pine scrub and sandhills. Many pollinator species are attracted to false rosemary, but bees are the most prominent visitor.
