Andropogon glomeratus (bushy bluestem) is another attractive grass that thrives in low moist areas.

Sorghastrum nutans (Indiangrass), another sod-former, is a tall (3-8 feet) yellow, prairie grass that can be quite showy and grows in almost any degree of light or moisture. Our resource, Native Plant Database, notes it favors an occasional flooding.

Speaking of our resource, the Wildflower Center webpage, you may want to search for some alternatives on your own at this site. Click on Explore Plants, then Native Plant Database. In a Combination Search, you can indicate your location and site characteristics. In addition to our suggestions, you will find a wide variety of other sedges and a few other grasses suitable for your situation. You may also use this resource to locate flowering species (herbs) to combine with the grasses for color, should you wish.

Some shade and moisture loving herbaceous specimens you might consider include Solidago juncea (early goldenrod). At 3-10 feet tall, it will keep pace with the tall grasses and adds its lovely golden plumes to the grassy mix. Add the Monarda didyma (scarlet beebalm), another tall shade-loving plant that is showy. Eupatorium purpureum (sweetscented joepyeweed) has a large pinkish flower and Eupatorium perfoliatum (common boneset) has fuzzy clusters of tiny white blossoms.

With a pond at the bottom of the slope you have an opportunity to plant practically into the water with wet loving plants. Consider the Viola cucullata (marsh blue violet), Equisetum hyemale (scouringrush horsetail), or plunge right in with the Nymphaea odorata (American white waterlily).

Oops! Mr. Smarty Plants digresses. Letʼs stick to the slope and consider how you will plant your choices. First, at our webpage, still in Explore Plants, click on Suppliers and enter your city and state. Several sources will come up for nurseries and seed companies, some of which we hope are close to Macon.
 
Next is planting the area. You may find grass plugs but seeding is more common. You could just broadcast the seeds but you risk having them wash down the hill at the next downpour. You may want to consider using an erosion-control blanket to hold those seeds where you want them. The seeds are sown under the material and grow through the  blanket matting. The roots below anchor the soil. Ask for a biodegradable material so the blanket gradually disappears leaving your lovely planted hillside.
 
Good luck!
