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.
