Florida scrub roseling (Callisia ornata) is a beautiful and delicate perennial wildflower in the dayflower family. Its pinkish-purple blooms are three-petaled with six stamens topped by bright yellow anthers. Its leaves are long, thin and grasslike with entire margins. They are alternately arranged and form a sheath at the base of the stem.
Florida scrub roseling typically blooms spring through autumn, but was recently spotted blooming in Brevard County. It is endemic to Florida and occurs naturally in scrub and sandhill habitats.
It is a close relative of (and its blooms look very similar to) spiderwort (Tradescantia spp.) and dayflower (Commelina spp.). And like these species, the Florida scrub roseling bloom is ephemeral, meaning it opens in the morning and closes by early afternoon.
The genus name Callisia is derived from the Greek word kallos, which means “beauty.”
Family: Commelinaceae (Dayflower or spiderwort family)
Native range: Central and southern peninsular Florida (excluding Monroe and Miami-Dade counties), as well as Gulf, Franklin and Wakulla counties in the Panhandle
