A low-growing coastal perennial with fine, needle-like evergreen foliage and tight clusters of pink, red, or white flowers. Extremely hardy and drought-tolerant, ideal for rock gardens, borders, and coastal landscapes.

Why grow it

Sea thrift offers reliable, low-maintenance performance in exposed coastal sites and poor soils where many ornamentals struggle. Its fine-textured foliage and compact mounding habit provide year-round structure in rock gardens and alpine troughs, while flowering extends from spring into early summer with minimal deadheading required. Compared to cushion phlox and alpine pinks, sea thrift tolerates salt spray and windy conditions more consistently across maritime climates.

Watch out for

In areas with high summer humidity or poorly draining soils, plants may succumb to root rot or fungal issues despite their general hardiness. Older plants can become woody and lose vigor after several years, making periodic division or rejuvenation pruning worthwhile. They prefer lean soils and may become lank or flower sparsely if grown in rich, heavily amended beds.
