Sea Sandwort (Honckenya peploides) is a perennial forb or herb native to coastal areas and wetlands across the Northern Hemisphere, including regions such as Alaska, Aleutian Islands, British Columbia, Connecticut, Denmark, Finland, and others listed in its extensive range. This plant is known for being both edible and ornamental, with its leaves, shoots, and seeds all being consumable parts. Sea Sandwort thrives in light (sandy) to medium soil conditions that are either dry or moist, preferring a pH of 7–7.5. It can grow up to 0.2 meters tall and is hardy in zones 4-8, making it adaptable to various climates within its native range. One distinctive feature of this plant is its ability to tolerate coastal environments, contributing to its presence in both sandy shores and inland wetlands.

Start with Sea Sandwort as a simple, low-maintenance perennial for your garden.
A small packet of seeds or young plants, a container or garden bed, and basic gardening tools.
Plant in early spring after the last frost or in late summer for fall hardening.
Ensure soil is well-draining with a pH of 7-7.5, either in a pot with light (sandy) to medium soil or directly in the garden.
Direct sow seeds just below the surface or plant young seedlings at a spacing of about 10 cm apart.
Keep the soil consistently moist and provide light shade if planting in full sun.
Water when the top inch of soil feels dry, and mulch to retain moisture. Fertilize sparingly with a balanced fertilizer.
