You can help restore the health of the Potomac River and the Chesapeake Bay by participating in Mason Neck State Park’s Grasses for the Masses program. Volunteers in the program grow wild celery, an important underwater grass, in their homes and then plant it at the park to help bolster aquatic grass populations. Underwater grasses are a vital part of the health of the
Potomac and the Chesapeake. They provide food for waterfowl, oxygenate the water, filter pollution, reduce erosion and provide safe spaces for newly-hatched fish.

To participate in the program, all you need to do is attend an orientation session at the park and pick up your supplies. There is a $25 charge for each Grasses Kit. You’ll grow your grasses at home, then plant them at the park on Planting Day, May 22. All supplies must be returned to the park on May 22.

Registration for the orientation programs is required, and there is a maximum of 10 persons for each orientation.

Native Grasses for our Yards

When we think of grass in our yards, the image that arises is likely to be that of turf grass. But there are many other places for grasses in our landscapes, and many other species available besides the European turf grass that is used for lawn. Grasses that are native to our region not only add beauty and texture in our gardens but also provide multiple environmental benefits.
 
This class of plants not only refers to true grasses (which tend to be sun-loving) but also to sedges (which are more often shade-loving) and rushes. Their size can range from tiny to gigantic. Clumps of taller grasses provide structural interest as well as motion and sound as the wind rustles through them. Shorter ones work as groundcovers. Some are evergreen, and all provide winter interest and seeds for the birds.
 
In shady areas with minimal foot traffic, some native grasses can be used as a substitute for conventional lawns, though this would require planting a lot of little plants at 8-10 inch intervals and a good deal of attention during establishment, not just throwing down seed. Deep soil amendment is critical on a typical compacted former lawn area which lacks good nutrition and may have alkaline soil, and it can take a few years for such lawns to get established.
 
Native grasses play a critical role in the ecosystem, providing
• Roots that are deeper than European turf grass and which do a better job at erosion control, breaking up hard soil and capturing stormwater
• Carbon sequestration
• Dense root structures that create a barrier to the spread of aggressive plants, creating pockets where more delicate plants can live
• Host plants for numerous species of butterflies, skippers, moths and others
• Food sources for birds and other wildlife
• Nesting material and cover.
Most of the plant material in a meadow consists of grasses, with colorful flowers tucked in between.
 
Several of the native grasses that are used as ornamentals are widely available in conventional nurseries, including the spectacular Pink Muhly Grass (Muhlenbergii capillaris), pictured above. (Be careful where you plant it, though – it needs good drainage!) Others can be purchased at one of the nurseries that specialize in native plants.
