Description
Sea fennel (Crithmum maritimum) is a succulent coastal herb that grows on cliff faces and rocky shores, tolerating both salt spray and dryness. Its fleshy, blue‑green leaves taste spicy‑salty with a subtle anise note, reminiscent of a blend of fennel and celery. Botanically, it belongs to the Asteraceae family and is unrelated to true fennel.
Care instructions
Sea fennel prefers full sun, a warm climate, and a very well‑drained, sandy or gravelly soil. Avoid heavy, water‑logged loam. Mix sand or gravel into the potting mix to mimic its natural rocky habitat. Water sparingly, allowing the soil to dry out between waterings; excess moisture is more harmful than drought. Fertilize lightly—over‑fertilization softens the leaves and reduces flavor. In containers, it tolerates winter best in a bright, cool spot; in the garden, a light mulch of straw can protect it from extreme cold.
