Scotch Moss-Tender Perennial

Fun for fairy gardens or the edge of containers!

Full sun to part shade.
Plants reach 1 inch tall and 6 to 12 inches wide;
very low moss-like ground cover.
Growth rate: Moderate.
Evergreen groundcover spreads slowly to form a dense, very low moss-like carpet of bright neon-yellow feathery foliage. Tiny white flowers appear in late spring to summer.
Tolerant of sandy or rocky soil, Sagina needs regular moisture, but do not like drought and/or soggy wet soils
Do not plant in a hot, dry location as this shallow-rooted plant may require daily watering
