Beach-pea thrives in sandy, well-drained coastal or garden soils with at least 6 hours of sun and tolerates some light shade. Water regularly to keep soil evenly moist, but ensure good drainage to prevent root rot. It is a nitrogen-fixing perennial that benefits neighbouring plants and requires minimal fertilisation once established.
