Genus:Eriocaulon

Species:compressum

Family:Eriocaulaceae

This wildflower stands tall, featuring a single, rounded flower head resembling a button atop a leafless stalk. It thrives in North Carolina and throughout the Mid-Atlantic, Southeastern, and Mid-South regions, often found along roadsides, in pinelands, and near ponds. The flower stalk can reach heights of 1 to 3 feet and emerges from a cluster of typically submerged, sheathed, linear basal leaves. Preferring damp soil or shallow water, this plant can also be utilized in flower arrangements, as its dried heads retain a white hue. It flourishes in wet or moist environments, making it suitable for pond edges or as a terrarium specimen indoors.

The name of this species is derived from the Greek terms "erio," meaning "wool," and "caul(o)," meaning "a stem," which alludes to the woolly hairs located at the base of the flowering scape. The species name "compressum" translates to "flattened sideways," likely referring to the flower heads that can appear flattened when pressed.
