Armeria grows best in full sun and free-draining, poor to moderately fertile soil so ideal for coastal gardens, rockeries, gravel borders, and edging paths. Water well during establishment, but once settled, it becomes drought tolerant and requires little irrigation.
Avoid rich soils or overfeeding, as this encourages weak, floppy growth and reduces flowering. Deadhead faded blooms regularly to prolong the display and maintain a tidy look.
Every few years, divide mature clumps in spring to keep them vigorous and compact. It dislikes winter wet, so ensure drainage is good—raise the planting area or add grit if necessary. In containers, use a gritty, low-fertility loam-based compost mix, such as John Innes No. 2, to mimic its natural conditions.
