Stolons are above ground runners, while rhizomes are under ground runners.
Both are stems that help produce plants and help warm season grasses fill in areas and recuperate after stress events. Common bermudagrass is easily established from seed. Hybrid bermudagrasses are the result of mating common bermudagrass with African bermudagrass. The result is a plant which has fine leaf texture and does not produce pollen or seed. They also have more individual shoots per square inch of turf than common bermudagrass.
