Sagina subulata Irish Moss



Sagina subulata is a moss-like plant with tufts of tiny, slender stems that grow together to form a lush carpet of green. Profuse tiny, white, fragrant flowers bloom in late spring. Also called Irish Moss, it is nice between stepping stones, in containers, or used as a ground cover in small areas. A perennial, Sagina subulata is usually evergreen and will naturalize in its favored conditions, self-sowing readily.

Sagina subulata prefers bright shade and moist soil. It must have ample moisture to grow in the sun. Irish Moss may become summer dormant in hot, humid areas. It can withstand heavy foot traffic. Space on 12" centers.

We ship via UPS & USPS (the Post Office), and their ship rates are automatically generated through our site. We do not profit on shipping costs. We are working with these providers to get our customers the best rates possible.

All ship times are subject to change if extreme weather conditions are present here at the nursery or at the shipping destination.

Please note: Depending on the time of year, the foliage of the plants may be trimmed to fit into our shipping boxes. This could delay the flowering of the plant, but many perennials actually benefit from being cut back.

We are currently not able to ship to Puerto Rico, Hawaii, and outside of the US.
