Irish Moss - Chondrus Crispus.
Irish moss, also known as Corsican pearlwort or Scot's moss, is not a moss at all. It is a member of the Caryophyllaceae family. Irish Moss is a herbaceous perennial that is a wonderfully elegant touch to any landscaping growing to more than 20 cm in length. The Irish Moss can vary in coloration ranging from greenish-yellowish, red, dark purple, purplish-brown, and can even have an emerald green color to it when the temperatures warm up. Irish moss also has pure white blooms that appear throughout its growing season. Due to the Irish moss' wide distribution, Irish Moss makes it a very versatile option for gardens in any location.
Irish moss looks similar to moss, and most people swear it is a moss until it blooms. The Irish Moss 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 an excellent 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.
Irish moss would make a great addition to any landscape.
