Gulf or Pink Muhly grass (Muhlenbergia capillaris) is a stunning ornamental grass known for its airy, pink-purple plumes that create a cloud-like effect in the landscape. Native to eastern North America, it thrives in a variety of environments, from coastal dunes to prairies. Jean-Baptiste Lamarck first described the plant in 1791 as Stipa capillaris, but it was later reclassified by Carl Bernhard von Trinius under the genus Muhlenbergia in 1824.
This grass is named after Henry Muhlenberg, an American botanist who made significant contributions to the field of plant taxonomy. It has been widely cultivated for its resilience and beauty, particularly in xeriscaping and sustainable landscaping projects. Pink Muhly grass was even recognized as the 2012 Plant of the Year by the Garden Club of America.
Essential cultural practices:
- Prefers full sun for optimal flowering
- Thrives in well-drained, sandy, or rocky soils
- Drought-tolerant once established, requiring minimal watering
- Benefits from occasional pruning in late winter or early spring to remove old growth
- Hardy in USDA zones 6-10, tolerating heat and humidity
- Works well in mass plantings, borders, and erosion control projects
- Attracts pollinators and provides habitat for beneficial insects
One of the most fascinating aspects of Pink Muhly grass is its ability to transform landscapes with its seasonal color shifts. During summer, its foliage remains green, but in autumn, it bursts into vibrant pink hues, creating a breathtaking display. It is also salt-tolerant, making it an excellent choice for coastal gardens.
Gulf Muhly grass is a low-maintenance, drought-resistant ornamental grass that adds texture and movement to gardens. Its historical significance, adaptability, and striking appearance make it a favorite among both landscapers and gardeners.
