Natural Plants
Concept
The desire to control erosion and eliminate the need for spraying or mowing on the sloped section between the fire hall parking lot and the bike trail led to discussion about planting natural grass with a deeper root system. The demonstration site along the bike trail behind the Watertown fire station is planted in sun-loving buffalograss, a natural grass that helps with erosion control due to the depth (8 foot deep) of its root system. Buffalograss makes an excellent replacement for ordinary (high maintenance) bluegrass lawns. Little to no maintenance (water or mowing) is needed once the stand is established. Perennial forbes (wildflowers) and other specimen grasses will be added as the stand prospers.

Buffalo grass is one of many warm season (heat loving) perennial grasses (persisting for several years with new growth from roots) that grew naturally in the past. It is a versatile low-growing grass that spreads by stolons and by root and by seed. "Due to its good soil cover and drought resistance, buffalograss is frequently favored for erosion control...and for low water lawns."

Natural Plants

Photos and descriptions of some of the prairie plants:

Big Bluestem grass, a perennial warm-season tallgrass plant reaches 3-7 feet in height with up to 8’ roots. The grass produces ‘turkey foot’ spikes and blades turn rust red in the fall.

Blue grama grass is a short, warm-season perennial growing 4-18 inches tall with ‘eyebrow’ shaped seed heads. Blue grama is drought tolerant.

Buffalograss, a warm season perennial shortgrass, reproduces by above-ground stems called stolons. Leaves are hairy and curly. Buffalograss is sun-loving and drought resistant. Once established, this grass requires little to no watering or mowing.

Leadplant, a shrubby perennial, grows 1-3 feet in height with violet flowers. Leadplant grows deep-roots, draws moisture from more than 4 feet below the surface.

Little bluestem, a warm-season perennial bunchgrass, grows 1-3 feet. The color is a light silver-blue and spikey looking.
