Care & Maintenance: Irish Moss

Irish Moss (Sagina Subulata) - Now offering the first ever pelleted Irish Moss seed!  If you have ever tried to plant Irish Moss seed before, you know the seed is like dust and very difficult to plant.  If you do not keep the seed moist outside, it can literally blow away.  Not any more!  Outsidepride is selling the first ever pelleted Irish Moss seed to make planting easier and to help the seed hold moisture while germinating.

Some of the images above are Irish Moss started from seed. Flowering occured approximately 3 months later, but this is quite variable. In just eight weeks, the Irish moss was thick and full. Grow this luxurious, evergreen ground cover plant from Irish Moss seed. Mossy foliage grows just 1 - 2 inches tall, for lovely color between flagstones or spilling over rocks. Dense tufts of slender stems grow together to form a lush carpet of green. Small, star-shaped, white flowers cover this flowering ground cover plant from late spring until mid-summer.

The very tiny Irish Moss seeds create a moss-like, emerald-green foliage that forms a compact 1 - 2 inch tall carpet. Sagina Subulata ground cover is excellent for planting between flagstones. Grown as a lawn substitute, it creates the effect of a moss-covered meadow. Irish Moss is very soft to walk on barefoot, and it has a slightly spongy feel to it.

How to Grow Irish Moss from Seeds: Sow Irish Moss seeds in starter flats, press the tiny seeds into soil but do not cover. Kept at 64 - 72F, germination is in 14 - 21 days. Transplant into the garden 6 - 9 inches apart. Irish Moss seeds can be direct sown into the garden or in-between stones. The ground cover seed must be kept moist continuously. It will be adaptable to mostly sunny locations in cooler climates or partial shade in warmer climates. Irish Moss ground cover needs moisture retentive, gritty, well-drained soil. The plants are hardy above -30F degrees.
