Coastalplain honeycombhead (Balduina angustifolia) is an annual to biennial wildflower that produces showy, golden blooms. Each flower consists of many yellow ray and disk florets, and each plant produces 20 or more flowerheads. As the plant matures, the ray florets fall off, but the disk florets remain yellow. Eventually, the disk florets dry up and form what resembles a honeycomb (hence the common name). Leaves are narrow with entire margins. They are alternately arranged. The plant spends its first year as a set of basal leaves; it will send up a stem in its second spring.
Honeycombhead typically blooms late spring or summer into fall. It occurs naturally in sandhills, scrub, dunes, and pine and scrubby flatwoods. It attracts a variety of butterflies, bees and other pollinators.
Honeycombhead is also known as yellow buttons.
