How to plant Irish Moss seeds

Irish Moss PR00879


Irish Moss is a fine-textured, ground hugging, slightly mounded perennial which resembles moss. Irish Moss is a terrific choice for filling in areas between flagstones, containers, or a small scale ground cover.

Plants produce tiny white flowers in spring or summer. Irish Moss needs afternoon shade, and moist, well-drained soil. Not recommended for climates that are both hot, and humid. Winter hardy to zone 5.

How to Plant Irish Moss Seeds

Sow Irish Moss seeds in cell packs or flats, press into soil but do not cover. Kept at 55-60° F., germination is in 10-25 days. Transplant into the garden 6 in. apart. Can direct sow in spring (when a light frost is still possible), or fall. However, because many birds like to eat Irish Moss seeds, we recommend starting them in flats.
