Irish moss is a springy, green plant. It is not to be confused with Chrondus crispus,a red algae of the same name that grows on the Atlantic coasts. In fact, it is not even a true moss, but is part of the Carnation family. With a mature height of 2-4 inches tall, it is an easy choice for ground cover. Sagina sublulata 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. This plant needs partial shade to grow. It flourishes in zones 3-9 depending on the variety. One such variety, subulata 'Aurea', or Scotch Moss, is a bright yellow green with tiny white blooms. Irish Moss can be propagated by taking cuttings and placing them in the desired area. Gardeners may also acquire seeds. These should be scattered on the soil, as they need sunlight to germinate, and take about 5-6 weeks to grow. Plugs or cuttings from mature plants will spread easily and rapidly. Irish Moss is a native of Europe and thrives in sandy or clay soil, so long as it receives enough water. In the heat of summer this plant sometimes turns brown, but can be revived by cooler weather and sufficient water in the fall. Irish Moss can often used to create a 'fairy' like appearance in containers because of its tiny flowers and delicate appearance. On rock walls or between secluded garden paths, Irish Moss creates a deep green palate on which other plants display their beauty. It is a low-maintenance plant that adds a peaceful, almost magical appearance to yards and gardens.
