Irish moss (Sagina subulata) is a low-maintenance groundcover that is perfect for use in rock gardens, between pavers, at the edges of a path, and as a low-footfall, limited area lawn substitute. This lush and low-growing evergreen perennial resembles moss, but it is part of the carnation family (Caryophyllaceae) and has much different growing requirements than moss. This is a very hardy but slow-growing plant that can take many months to fill out in the garden. How to Grow Irish Moss From Seed It is possible to sow Irish moss directly in the ground in the spring, however, because the birds like to eat the seeds, it is recommended to start Irish moss in seed flats indoors about one month before your last average frost date. Lightly press the seeds into the soil but do not cover, as they need light to germinate. Kept the flat moist at all times and at a temperature between 55 and 60 degrees Fahrenheit. Harden off the seedlings before transplanting them outdoors after the last spring frost.
