How to Grow and Care
Growing Rock Samphire in the garden is very easy. Although it is used to salty coastal soil, it will do well in any well-draining soil and has been cultivated in gardens in England for centuries.
Sow seeds indoors a few weeks before the average last frost. Transplant the seedlings outside after all chance of frost has passed.
Rock Samphire can tolerate some shade, but it will perform best in full sun. It is a good idea to dig a large hole and fill the bottom of it with gravel to make drainage easier. Allow the soil to dry out between waterings.
Harvest young leaves and stems throughout spring and summer by handpicking or cutting with scissors, similar to the harvesting of most common herb plants. See more at How to Grow and Care for a Rock Samphire (Crithmum maritimum).
Crithmum maritimum is found on the southern and western coasts of Britain and Ireland, on the Mediterranean and western coasts of Europe, including the Canary Islands, North Africa, and the Black Sea.
