- Care & Maintenance: See: Irish Moss
Irish Moss (Sagina Subulata) - Just click the first 4 pictures above to see Irish Moss seeds planted after 2 weeks, 4 weeks, and 8 weeks. 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 seeds! 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: 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.
