Muhlenbergia glomerata, commonly known as Spiked Muhly or Marsh Muhly, is a perennial grass native to North America, particularly found in wetlands and moist meadows of Canada and the northern United States. It typically grows up to 4 feet tall and features narrow panicles of spikelets that are purplish-green in color. This grass is most commonly found in moist habitats such as bogs, marshes, wet meadows, and along lakeshores, where it contributes to the ecological health of these areas by providing habitat and food for wildlife.

Spiked Muhly is valued for its adaptability to wet conditions and is often used in rain gardens, as a border plant in water features, or for naturalizing in wetland restoration projects. It thrives in full sun to part shade and prefers consistently moist to wet soils. While it is not particularly drought-tolerant, it can survive occasional dry spells once established. Its ability to grow in standing water makes it an excellent choice for erosion control along waterways. Spiked Muhly does not have significant disease or pest problems, but it can spread aggressively in ideal conditions, so care should be taken to manage its growth in smaller garden settings.CC BY-SA 4.0
