About Sea plantain
Plantago maritima, known as sea plantain or strandkjempe, is a low-growing perennial herbaceous plant native to coastal areas and salt marshes. It features narrow, fleshy leaves arranged in a basal rosette and produces inconspicuous flower spikes. It is ideal for coastal gardens, rockeries, or as ground cover in salt-exposed areas, offering a natural and resilient aesthetic.
Native range
Coasts and saline areas of Europe, Asia, and North Africa
Care tips
It thrives in full sun to partial shade and tolerates both airborne and soil salinity well. Watering should be moderate, allowing the substrate to dry out slightly between waterings, as it is drought-tolerant once established. It prefers well-drained, sandy or stony soils, and can even thrive in poor soils. A common mistake is overwatering, which can lead to root rot.
