For much of the year, Fragrant eryngo (Eryngium aromaticum) goes unnoticed among the diverse flora of Florida’s dry flatwoods, scrub and sandhills. However, when it bursts into bloom in summer through late fall, the petite white to light blue flowers can be found in abundance. Almost endemic to our state, it also ranges slightly into Alabama and Georgia.

Stems are 1-2 feet long, prostrate, and emerge from a basal rosette of dissected leaves with spiny tips. These light green stems bear alternate leaves that are even more deeply dissected than those at the base. Numerous flowerheads form at the end of each stem. Individual flowerheads are about ½ inch in diameter, globular and are surrounded by spiny bracts. With the sprawling habit of the stems, these plants stand only about 6 inches to 1 foot high.

Fragrant eryngo attracts numerous pollinators including sweat bees, thread-waisted wasps and small potter wasps. It is also a larval host for the Eastern black swallowtail butterfly.
