Irish Moss

Irish Moss (Sagina subulata)

Irish Moss (Sagina subulata) is a low-growing, evergreen groundcover prized for its dense, carpet-like texture and soft, bright green foliage. This versatile plant adds a lush, refined appearance and an attractive focal point to garden paths, rock gardens, and shaded borders.

Distinctive Features

'Sagina subulata' forms a dense, moss-like mat of tiny, bright green foliage that creates a soft, cushiony texture in the landscape. In late spring to early summer, it produces small, star-shaped white flowers that add delicate charm to its low-growing form. Ideal for filling spaces between stepping stones, along walkways, or as an edging plant, Irish Moss thrives in cool, moist conditions. Its compact habit, growing only 1 to 2 inches tall, makes it perfect for small spaces and garden accents. The evergreen foliage remains attractive year-round, offering seasonal interest even in winter.
