Irish Moss – Sagina Subulata
Irish moss looks similar to moss, and most people swear it is a moss until it blooms. The blooms have small white flowers which other mosses do not. Moss plants do not have blooms. Moss is primitive plants that never contain a bloom. This moss is thick and dense. It has bright green leaves and stems. The white blossoms are tiny and sporadically placed, but they are enough to cover the plant. This plant is a natural grower and is a good plant for a beginner. As this plant is growing, it looks similar to a clump of algae growing or a mat.
The Irish moss looks well placed throughout a rock garden or an area that does not have a lot of other plants already growing. It can tolerate some foot traffic so planting this plant near where one is walking will not be a problem. Irish moss is considered a seaweed, so cold water is best for it, and it is often used in raw food diets. It has been used in Ireland, Asia, and North America for centuries.
