Recently moved to a home in Mount Pleasant and the previous owner planted several of these plants around the property. We are less than 50 feet from wetlands and I’m not sure if these might be invasive. Stand 4-5 feet tall with multiple roots (possibly rhizome). Receives 5-7 hours of sunlight/ Thank you in advance
your plant is a commonly grown ornamental sedge named Cyperus alternifolius, or the umbrella sedge. It is not native here, but is said to be native to Madagascar. I do not consider it invasive, because it is a clustering sedge. They are usually grown in or near water, or as house plants.
