The Pennsylvania Sedge is a hardy grass-like plant that goes by several different names including Early Sedge, Sun Sedge and Penn Sedge. It stands out among sedges because it does not require moist soil. It prefers the dry conditions and dappled shade that are found in its natural forest habitat where it often grows under oak trees, giving it another name, Oak Sedge. It will tolerate a wide range of conditions from wet to dry soil and from full sun to full shade. Pennsylvania Sedge is hardy from Zone 3 to 8. It gains between 3 and 8 inches of spread each year, making it a great choice for ground cover, especially in a dry, shady part of the garden. Pennsylvania Sedge can substitute for grass in difficult areas because it can be mowed to a height of 2 inches or left alone to create a flowing grassland. Its tiny yellow flowers come out in May and June, but they are easily overlooked, so this sedge works best as a backdrop for showier flowering plants. Although spreading will occur naturally, many gardeners choose to divide the plants each year in order to create dense stands, which are especially striking in a rock garden. A low-growing, delicate sedge, it forms loose, feathery clumps up to 8 inches tall by 8 inches wide. Its narrow (1/8-inch) leaves arch gracefully from the center of the plant; flower spikes sprout up from the mound to a height of 12 inches. The plant is semi-evergreen in regions with moderately cold winters. Birds love sedges, and the Pennsylvania Sedge is no exception. It attracts many species that feed on the seeds and use the fallen leaves to make nests. This sedge is challenging to grow from seed, so it is best to purchase bare root plants for fastest growth.
