Design Tips

Star Sedge forms short lime-green mounds in early spring, with interesting star-like seed heads that form later and splay out a little bit. It’s a valuable plant that can be scattered throughout a prairie garden to give green growth during the spring when all of the warm-season plants are still dormant and brown.
