How to Grow Irish Moss

IRISH MOSS Growing

​

Irish moss ~ Sagina subulata

​

This beautiful groundcover features dense tufts of slender stems which grow together to form a lush carpet of green. In spring, the mass of small, star-shaped, white flowers are a delight.
Whilst preferring some shade and good drainage it is a tough little plant but it will require water through a hot summer.

This is one of our favourites as it has an intriguing mounding effect if left unmown. Mounds may get to 75mm in height.

Imagine! Create a striking checkerboard effect between pavers.

Ideal for…
• Great as a soft alternative lawn that does not require mowing!
• A feature between rocks and stones
• Best suited to temperate climates as it does not like humidity
• In the garden bed to add a touch of cool green

Irish Moss Care Must-Knows

Irish moss grows well in average, well-drained soil. In cool climates, select a full-sun planting site. In hot Southern climates, plant Irish moss in bright shade. A spot that receives morning sun and afternoon shade is a good choice in Zones 7 and above.

Plant Irish moss in spring or early summer. Situate plants about 10 inches apart; in ideal conditions, they will grow together to form a carpet of color in a couple of seasons. Plant Irish moss closer together for faster cover. Prolonged periods of hot, humid weather are not good for Irish moss. It thrives in cool, somewhat dry environments. Don’t be surprised if it dies out in the heat of summer in humid areas.
