Irish Moss - Chondrus crispus
Irish Moss, also known as Pearlwort, is a popular choice for a gardener that wants a unique touch for their area. It grows best in light shade to full sun and in good, well-drained soil. Despite its name, Irish Moss is not actually a true moss, but a flowering plant that mimics the appearance of moss. The plant is well-known for its dense, deep green array of tiny leaves and stems that reach no more than one inch in height. Low to the ground, this creeping perennial plant serves as a low-maintenance alternative to the conventional grass lawn. From early to late spring, tiny white star-shaped flowers are widespread enough to cover the entire plant and give off a light fragrance. It’s perfect for planting along walkways, between stepping stones or even in a rock garden. The vegetation tolerates moderate foot traffic and feels like a cushy mat under one’s feet. One of the main reasons that many people opt for Irish Moss over traditional turf is due to the fact that it requires little to no maintenance aside from weeding. There's no need to mow the moss or trim it, which saves you time and effort when compared to traditional lawnsIrish moss is a springy, green plant. It is not to be confused with Chrondus Crispus, red algae of the same name that grows on the Atlantic coasts. In fact, it is not even a real moss but is part of the Carnation family. It is a spreading plant that produces tiny white blooms in late spring and summer. It can grow in lumpy formations that are easily cut out if desired. It can be used as a surprising turf replacement, for edging on paths, rock walls, and between paving stones, and as a component in decorating. One such variety, subulata 'Aurea,' or Scotch Moss, is a bright yellow-green with tiny white blooms.
