About plant names...

This salt-tolerant member of the aster family is found in saltwater marshes, tidal flats, and lagoons. It is native to the southeastern United States.

Plants: These shrubby plants form colonies. Plants are 24-48" (60-121 cm) high.

Leaves: Leaves are fleshy, opposite, gray-green, obovate, and fuzzy, with fine hairs on both sides, 2-4" (5-10 cm) long.

Flowers: Flowers are yellow, appearing July-August. A single flower appears atop each stem. Each flower has 15-30 yellow rays and brownish-yellow flowers in the central disc. The central disc contains 20-75 ray florets.

Fruits: Ray flowers fall off, leaving a central brown dome of sharp projections. A single barely noticeable 4-sided achene, shaped like a pointed tooth and ¹/₁₆-⅛" (3-4 mm) long, is produced in each flowerhead.
