White stopper(Eugenia axillaris) is an evergreen shrub or small tree found in coastal hammocks, strands and shell mounds in Florida’s central and southern peninsula. Its fragrant flowers bloom year-round, with peak blooming in spring and summer, attracting many types of pollinators. Fruits generally form in fall, but may persist several months. They are eaten by birds and wildlife. Humans can eat them, too — the flesh is quite sweet when ripe,  but eating the bitter seeds is not recommended. 

White stopper’s flowers are 4-petaled with many obvious stamens that give them a frilly appearance. They are born in axillary clusters. Leaves are elliptic to ovate, dark green on top and pale underneath with entire margins and reddish petioles. Young leaves may be pinkish or red. Mature leaves may be studded with black dots. Leaf arrangement is opposite. Trunk is smooth with grayish bark. Fruits are round, medium-sized (about ½–inch in diameter) fleshy berries. Immature fruits are green; mature fruit color varies from red to purplish-black.  

The common name “stopper” alludes to the plant’s historical use as a treatment for diarrhea.
