Sagina subulata - Irish Moss, Sandwort: This is an excellent choice for interplanting between patio stones and rock gardens. Very tiny white flowers contrast beautifully with the dense, dark green foliage.
I can so envision an outdoor room with moss/plant covered furniture, window frames w/ window boxes on surrounding fence walls. Maybe I should try this as a mini garden. Outdoor story chair for school. Epic and moveable!
