Irish 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.
