Sedum lineare 'Sea Urchin' is a charming, fine-textured evergreen groundcover known for its dense, spiky foliage that resembles the spines of a sea urchin. Its bright green needle-like leaves form tight mats that spread gracefully, making it ideal for edging, rock gardens, green roofs, or container plantings. This low-growing sedum adds a refined, delicate look while being tough, drought-tolerant, and virtually maintenance-free.
Its compact, mounding habit contrasts beautifully with coarser plants and adds texture year-round. In summer, small yellow star-shaped flowers dot the foliage, adding seasonal interest and attracting pollinators.
