Sea Pink is a compact, evergreen perennial native to coastal regions that forms dense, low-growing mounds of narrow, grass-like foliage topped with papery flower heads in pink, red, or white. It thrives in poor, sandy soils and rocky conditions, making it ideal for alpine gardens, rock gardens, and coastal landscapes. This hardy plant is valued for its long blooming season and tolerance of salt spray and challenging growing conditions.

Growth Stages

1

Germination

1-3 weeks

Tiny seedlings emerge with minimal cotyledons and fine, thread-like first leaves.

Keep soil moist but not waterlogged. Provide bright light. Germination occurs at 60-70°F and takes 10-20 days.

2

Seedling/Rosette Formation

4-8 weeks

Plants develop dense rosettes of narrow, grass-like foliage in tight mounds. Growth is slow initially.

Provide good drainage and avoid dampness. Begin hardening off before transplanting. Fertilize lightly if needed.

3

Vegetative Growth

4-8 weeks

Foliage mounds become fuller and denser. Plant establishes deep root system. No flowers yet.

Water moderately during dry spells. Thin seedlings or transplant as needed. Reduce watering in cooler months.

4

Flowering

8-12 weeks (spring to summer)

Dense flower heads (pompoms) appear on stiff stems above foliage in shades of pink, red, or white. Blooms are papery and long-lasting.

Deadhead spent flowers to encourage continued blooming. Avoid excessive watering. Support plants if needed in windy sites.

5

Post-Bloom/Dormancy

4-6 months

Foliage remains evergreen. Seed heads may persist. Plant enters dormancy in fall/winter.

Divide plants every 3-4 years to rejuvenate. Remove accumulated dead foliage carefully. Provide excellent drainage for winter survival.
