Planting instructions for sea blush: This plant is a winter annual, which means you can sow it in fall, and it will overwinter and have a head start in spring. I like sowing it in early October. (Early spring also works.) Make sure to give it bare soil - it will do poorly if sown into established vegetation, or where there is lots of competition from other germinating seeds. Thin, poor, rocky soil is no problem. A garden bed is fine. Cracks in between pavers is great. Full sun to part shade. Sea blush will readily self-sow if bare soil is available.
