Sites with poor-drainage, can be difficult for traditional lawn grass, which generally prefers free-draining soil and sun. If the site is truly waterlogged, you may struggle to maintain a mowable lawn, even using native species. Though you may not be able to maintain turf-like grass, consider planting this low-growing, grassy rain-garden. You may not achieve perfect mowable turf, but this mix of handsom, native grass-like sedges, which are typically found by streams and in wet meadows, will produce a lush green landscape in full sun. Finished heights on this mix will be about two to five feet, but once established it can be mowed one or two times per year to keep it looking as trim and attractive as any prized lawn.
