Grasses in Masses

by Anna Mische John
Vegetation Maintenance Supervisor

Often people only think of grass as the short green stuff in a front yard or play field, but did you know that there are over 200 species of grass native to the state of Maryland? The short stuff (referred to as turf when in a mowed setting) can have utility as a play space and permeable ground cover, but from an ecological perspective, it doesn’t offer much.

Native grasses, on the other hand, support insects and birds by offering habitat. And they have ecological benefits, including soil stabilization and structure.

Ornamental bunch grasses have been used in gardens and landscapes for decades. Allowed to grow to full height and flower, they can be an interesting addition to perennial plantings. However, just like flowers and trees, some of the grasses planted for ornamental use are invasive and may escape from where they are planted, becoming established in natural areas, displacing other plants.

This spring, the vegetation maintenance team replanted six traffic-calming areas along Ritchie Avenue between Piney Branch Rd. and Oswego Ave., each featuring a single grass species with an informational label.

With this project I hope to both spotlight some of the beautiful Maryland grasses for their potential for ecological benefit, as well as offer alternatives to some of the ornamental invasive grasses (namely Miscanthus/Chinese silver grass and Pennisetum/fountain grass). Species were chosen for commercial availability, adaptability to roadside conditions, and “garden worthiness.”

I hope you will enjoy taking a tour of the grasses in masses on Ritchie Ave. Come now to see them in flower and throughout the year to see how they change with the seasons.

Want more? Continue around the traffic circle to Heffner Park to see Indian Grass (Sorghastrum nutans), this tall species was once the dominant grass of eastern tall grass prairies.
