Dioecious Sedge (Carex dioica and Carex sterilis)
Dioecious Sedge refers to several species of sedges within the Carex genus, most notably Carex dioica and Carex sterilis. It is named for its dioecious nature, meaning that male and female reproductive structures are found on separate plants. It is also known as sterile sedge. It is a flowering perennial plant that can grow up to 10 inches (approximately 25 cm), though one source states that it can grow to 40cm.
