Also known as Corsican pearlwort or Scotch moss, Irish moss (Sagina subulata) is a perennial ground cover notable for its tight, low growth habit, emerald green foliage and pristine white flowers, which appear in the spring. It generally grows in U.S. Department of Agriculture plant hardiness zones 4 through 8. Irish moss is generally a trouble-free, durable plant, though like any plant, it is susceptible to a few pests and cultural problems.
