Armeria maritima
A compact, evergreen perennial forming tidy, grass-like mounds of narrow dark green foliage roughly 6 to 10 inches tall, topped in spring and early summer with round, papery flower heads in pink to rose on slender stems. It prefers full sun, tolerates lean and sandy soils, and needs good drainage with low to moderate water, performing well in coastal and saline conditions. Use it for border edging, rock gardens, parkway strips, and tidy front-of-bed massing where a neat, long-blooming cushion is wanted.
