This unassuming little native sedge may not win any beauty contests, but it’s got that quiet charm that makes native plant enthusiasts take notice.
What Is Caribbean Island Spikesedge?

Don’t let the name fool you – while it looks like grass, it’s actually part of the sedge family (Cyperaceae), which makes it a cousin to more familiar sedges and rushes. You might also see it listed under its botanical synonyms Cyperus obtusatus or Kyllinga pungens in older gardening references.
This little plant forms low, dense mats and has that classic grass-like appearance that makes sedges so useful in landscape design. It’s the kind of plant that quietly does its job without demanding much attention – perfect for gardeners who appreciate understated natives.
